How the properties of a compound and the properties of its component compare
The properties of compounds are different from the properties of the elements that form them because elements in a compound combine and become an entirely different substance with its own unique properties.
What are compounds?A compound is described as a material formed by chemically bonding two or more chemical elements.
When elements combine in a any specific ratio, compounds are formed. These compounds are totally different from the elements that compose them.
As these elements combine to form compounds, the individual properties of the combining elements are no longer observed. Only the properties of the compound formed is now observed.
In conclusion, we can say that the physical properties of any compound are often quite different to the physical properties of the elements that made them up.

according to dr. al-khalili, why were scientists interested in atomic theory in the mid nineteenth century?
Scientists interested in atomic theory in the mid nineteenth century because of steam.
The scientific theory known as "atomic theory" states that atoms are the basic building blocks of matter. Atomism, a prehistoric intellectual movement, is where the atomic hypothesis had its start. This notion held that if a lump of stuff were divided into ever-smaller parts, one would ultimately reach a point where the smaller components could not be divided any further. These fictitious fundamental elements of substance were given the Greek term atomos, which means "uncut," by the ancient thinkers.
John Dalton, a chemist, observed that, in the early 1800s, chemical compounds appeared to mix and decompose into other substances in weight proportions that suggested that each chemical element is ultimately composed of minute, indivisible particles of constant weight.

the substance oxidized causes the other substance to be reduced and is called the: group of answer choices reducing agent oxidizing agent private agent the oxidizer
The oxidised substance reduces the other substance and is known as reducing agent.
what is reducing agent ?
A reducing agent is a chemical species that "donates" an electrons to an electron receiver (called the oxidising agent, oxidant, oxidizer, or electron acceptor). Earth metals, formic acid, oxalic acid, and sulfite compounds are examples of common reducing agents.
Reducers contain additional electrons in their pre-reaction states (that is, they are themselves reduced), whereas oxidizers lack electrons (that is, they are by themselves oxidized). This is often stated in terms of their oxidation states. The oxidation state of an agent specifies the degree of electron loss, with the higher the oxidation state having fewer electrons.

What's the difference between an ionic bond and a covalent bond? an electric current is trying to move through an atom. How do protons and electrons impact the movement of electricity?.
The main difference between an ionic bond and a covalent bond is that electrons are transferred in an ionic bond, whereas electrons are shared in a covalent bond.
Ionic bond is formed by donating or transferring the electron by one atom to the another. The atoms which takes part in ionic bond have different electronegativity values. The nature of a bond is polar in the ionic bond as bond is formed between oppositely charged ions.
Covalent bond in the compound is formed by sharing of electrons between two atoms. If the electrons are equally shared, then the nature of a bond is polar covalent bond. The polar covalent bond is formed due to electrons are more attracted to one atom than another.
