Consider the following neutral electron configurations in which n has a constant value. which configuration would belong to the element with the most negative electron affinity, eea? view available hint(s) consider the following neutral electron configurations in which n has a constant value. which configuration would belong to the element with the most negative electron affinity, a. 5s2 b. 5s25p2 c. 5s25p5 d. 5s25p6

"c" is the element with the most negative electron affinity.

Explanation:

We can obtain the following information from the electron configuration:

Period: Is the level in which the differential electron is in.

Group: Is the sum of all electrons in the last level.

Knowing their ubication in the periodic table, we can classify them as metals, nonmetals or noble gases.

a. 5s²            P: 5    G: IIA (2) Metal

b. 5s²5p²      P: 5    G: 2 + 2 = IVA (14) Nonmetal

c. 5s²5p⁵      P: 5    G: 2 + 5 = VIIA (17) Nonmetal

d. 5s²5p⁶      P: 5    G: 2 + 6 = VIIIA (18) Noble gas

Noble metals have a low tendency to gain electrons so their electron affinity is neglectable. For elements in the same period, the electron affinity gets more negative from left to right. Therefore, "c" is the element with the most negative electron affinity.

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

b.false that your answer
