6s^2 6p^6
4f^14 5d^10 6s^2 6p^3
6p^3
6s^2 6p^3

Answers

Answer 1

The correct electron configuration for the valence electrons of Bi (bismuth) in the ground state is: [tex]6s^2 6p^3[/tex] .

In the periodic table, bismuth (Bi) is located in Group 15 or Group VA. The electron configuration describes how the electrons are distributed in different energy levels or orbitals of an atom.

Bismuth has a total of 83 electrons. The electron configuration starts with the lowest energy level and fills up to higher energy levels. The first energy level (n = 1) can hold a maximum of 2 electrons, the second energy level (n = 2) can hold a maximum of 8 electrons, and so on.

For bismuth, the electron configuration is:[tex]1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^14 5d^10 6p^3.[/tex]

The valence electrons are the outermost electrons in an atom, and they play a crucial role in determining the chemical properties of an element. In the case of bismuth, the valence electrons are in the 6s and 6p orbitals. The[tex]6s^2[/tex] portion represents the 6s subshell, which can hold a maximum of 2 electrons, and the [tex]6p^3[/tex]portion represents the 6p subshell, which can hold a maximum of 6 electrons.

The valence electron configuration of [tex]6s^2 6p^3[/tex] indicates that bismuth has 2 valence electrons in the 6s orbital and 3 valence electrons in the 6p orbital. These valence electrons are involved in the bonding and chemical reactions of bismuth with other elements.

Understanding the electron configuration is important in studying the chemical behavior and properties of elements, as it provides insights into the arrangement and interactions of electrons in an atom.

If we evenly distribute the 1000 pages among four PNs, then the computation time can be reduced to 1000/4 or 250D (due to parallel scanning). On the other hand, if one of the PN has more data (data skew), 30% of the total data size, the overall computation time increases to 1000x0.3 or 300D. 1. (25 pts.) We have a shared-nothing system with four processing nodes (PNs). The Grace algorithm is used to join two relations R and S as discussed in class. Each relation has 1,000,000 tuples stored in 10,000 pages. We make the following assumptions: o The two operand relations are initially evenly distributed among the four PNs. o Data skew does not occur (i.e., the workload is balanced throughout the computation). o 2-Phase join is used to join the bucket pairs. Probing the hash table to find the matches incurs negligible computation time. o Read or write a page takes D time units. o Communication time is negligible. Estimate the computation time (i.e., response time) for this join operation. 2. (25 pts.) Consider the same join operation described in Q 1, but with a data skew problem. The Hash Phase results in PN1 having 40% of the total data from each of the operand relations. Estimate the computation time of this join operation using Grace algorithm. 3. (25 pts.) We apply TIJ to join two relations R and S, each with 1,000,000 tuples stored in 10,000 pages. Initially, PN1 has 40% of the R and S tuples. PN2, PN3, and PN4 each has 20% of the total tuples. Estimate the computation time of this join operation. 4. (25 pts.)
