Answer 1

The electron configurations are provided for lithium, fluorine, carbon, argon, sulfur, nickel, rubidium, and xenon. The elements corresponding to the given electron configurations are identified as fluorine, calcium, tellurium, and bromine.

Step-by-step explanation:

Electron Configuration of Selected Elements

The complete electron configuration for the given elements is as follows:

Lithium (Li): 1s² 2s¹

Fluorine (F): 1s² 2s² 2p⁵

Carbon (C): 1s² 2s² 2p²

Argon (Ar): 1s² 2s² 2p⁶ 3s² 3p⁶

Sulfur (S): 1s² 2s² 2p⁶ 3s² 3p⁴

Nickel (Ni): 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s²

Rubidium (Rb): 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s¹

Xenon (Xe): 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶

Identification of Elements Based on Electron Configurations

The elements represented by each electron configuration are:

a. 1s² 2s² 2p⁵ is Fluorine (F).

b. 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² is Calcium (Ca).

c. 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁴ is Tellurium (Te).

d. 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵ is Bromine (Br).

Answer 2

Step-by-step explanation:

Answer 1:

Lithium : 1s2 2s1 Fluorine: 1s2 2s2 2p5 Carbon: 1s2 2s2 2p2

Argon : 1s2 2s2 2p6 3s2 3p6 Sulphur: 1s2 2s2 2p6 3s2 3p4

Nickel: 1s2 2s2 2p6 3s2 3p6 3d8 4s2 Rubidium: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s1 Xenon: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6

Answer 2: A. Fluorine B. Calcium

C. It is Tellurium if this was the exact electronic configuration 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p4 you intend to write, if not, no element has such electonic configuration.

D. Bromine but the correct electronic configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p5
