Answer: Neon is not reactive (full valence shell)
Explanation:
Neon is a noble gas and has a stable structure (8 valence electrons) -therefore, is not very reactive.
What Element am I?
I have 6 Valence Electrons.
I am in the third row.
My atomic mass is less than Selenium , but it is more than Oxygen. I need the answer ASAP
Answer:
The correct answer is - sulfur.
Explanation:
In the periodic table, there are 18 groups and 7 rows or periods arranged according to their atomic number or electronic configuration. In the question, it is mentioned that the desired element atomic mass is less than the atomic mass of the selenium which is 78.96, and more than oxygen which is 15.99 with 6 electron valence and present in the third row.
As it has 6 valency of electron it must be in the 16 group of the table that comprises the 6 valency and as it is located in the 3rd row it must be sulfur that also has an atomic mass between selenium and oxygen.

If you shine the world’s brightest flashlight at a black hole, will the light shine through the black hole, or will the black hole consume the light?
yes the flaslight would beconsumed by the black hole. So yeah
Explanation:
Answer:
if you were to aim a powerful-enough flashlight at the Moon right now, the light would reach it in a little more than a second—maybe before you got to the end of this sentence. . If you aimed your flashlight in its direction, toward the constellation Sagittarius, the light would arrive there sometime around the year 3600.

Every spring has an equilibrium position. Which statements describe a spring at its equilibrium position ? Check all that apply.
The spring constant is zero.
The elastic potential energy is at a maximum.
The elastic potential energy is zero
The displacement of the spring is at a maximum.
The net force acting on the spring is zero.
Answer:
The elastic potential energy is zero.
The net force acting on the spring is zero.
The statements correct about the equilibrium position of Spring has been that the elastic potential energy and the net force acting on the spring has been zero at the equilibrium position. Thus statements C and E are correct.
The spring displacement can be described by Hooke's law. According to Hooke's law, the force required for the stretching and compression of the spring has been dependent on the spring stretch, and the spring constant.
The spring constant has been a non-zero quantity. Thus statement A is incorrect.The elastic potential energy of the spring has been the energy stored in the spring. At the equilibrium position, the elastic potential energy of the spring has been zero, as there has been the total kinetic energy.Thus statement B is incorrect, and C is correct.
The displacement of the spring at equilibrium position has been zero. Thus statement D is incorrect.The net force acting on the spring has been zero at the equilibrium position. Thus statement E is correct.For more information about the spring equilibrium position, refer to the link:

What would happen if you tried to break down a sample of sulfur?
Answer:
You can't actually break down pure sulfur because it is a element but with peroxide it would break down but only very slowly.
Explanation:
Sulfur forms different compounds with metals and non-metals also.When a sulfur sample is breakdown, there occurs a chemical change and the decomposed products such as sulphided forms.
What is sulfur?Sulfur is 16th element in the periodic table. It is a non metal and classified into the 16th group called oxygen family. Other group members of sulfur are thus, oxygen, tellurium, polonium and selenium.
Sulfur forms mostly covalent compounds by sharing its electrons with non-metals such as hydrogen, oxygen, nitrogen and some ionic compounds with metals such as iron, cobalt, nickel etc.
When a chemical change occurs, there will be a bond making or bond breaking and results in the formation of new products or the decomposition of the initial product into its constituents.
Sulfur produce a foul smell and when a sulfur sample is broken, it will form odour full sulphide ions or sulphates. For example in the case of metal sulphides, if broken the broken parts cannot be distinguished from the initial if it is chemically tested.

In mid-summer, a family assembled a patio set for their deck. Most of the assembling
was done by placing metal screws into plastic holes. The furniture was stable
throughout the summer. However, when the weather turned cold in the late fall, the
family noticed that the chairs and table became wobbly. Which statement best
explains what happened?
1. Plastic has greater thermal expansion than metal does.
2. Both plastic and metal contract when warm and expand when cold.
3. The metal screws contracted more than the plastic did when they became cold.
4. The metal screws contracted less than the plastic did when they became cold
Answer:
The metal screws contracted more than the plastic did when they became cold.
Explanation:
The metal screws contracted more than the plastic did when they became cold. Thus option 3 is correct.
What is metal?Metal is defined as a class of substances distinguished by high electrical and thermal conductivity, as well as malleability, ductility, and high light reflectivity.
It can also be defined as a material having a high electrical conductivity, luster, and malleability that rapidly loses electrons to produce positive ions (cations).
Metals are classified based on their place on the Periodic Table.
Plastic is defined as a diverse spectrum of synthetic or semi-synthetic materials containing polymers as a primary component.
Thus, the metal screws contracted more than the plastic did when they became cold. Thus option 3 is correct.

Is a salad a example of heterogeneous mixture?
Answer: Yes
Explanation: A heterogeneous mixture is a mixture that is different thoroughly.
Answer:
Yes!
Explanation:
A heterogeneous mixture does not have a uniform composition, unlike a homogeneous mixture. This means the mixture can easily be separated (by physical means). A salad has many different components such as lettuce, tomatoes, etc. that are easily distinguishable, making it heterogeneous.

What most likely led to a change in the widely accepted theory of evolution? new experiments involving genes and evolution experiments with Darwin's original hypotheses changes that Mendel made to his laws of genes studies of evolution without Mendel's laws
Incomplete question. Full question reads;
Darwin developed the theory of evolution to explain why there are so many different kinds of living things. He could easily observe that offspring of any animals were slightly different from their parents and that this could allow for big changes over thousands of years. He did not know that genes caused the differences. Genes are now very important in the modern theory of evolution.
What most likely led to a change in the widely accepted theory of evolution?
Answer:
new experiments involving genes and evolution
Explanation:
Indeed, the original theory of evolution has experienced several changes in its acceptance because of its imperfect and wrong assumptions not based on generally acceptable scientific facts,
Hence, new experiments involving genes and evolution has led to a change (disagreements and few agreements) in the widely accepted theory of evolution.

An element has two naturally occurring isotopes. One is 10.013 amu and is 19.9% abundant. The other is 11.01 amu and is 80.1% abundant. What is the average atomic mass? What element is it?
Answer:
10.81, Boron
Explanation:
I love the explanation Khan Academy gives.
The average atomic mass of the element is 10.811 u.
What is Average Atomic Mass ?
The average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element.
Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei.
Hence, differ in relative atomic mass but not in chemical properties; in particular, a bform of an element.
Therefore, The average atomic mass of the element is 10.811 u.

What identifies an atom as iron atom?
Answer:
Explanation:
An atom is composed of three particles -- protons, neutrons and electrons. The number of protons is the defining characteristic of an element, and this number also tells you how many electrons are present in a neutral atom. Therefore, iron -- with an atomic number of 26 -- has 26 protons and electrons.
