What is the electron configuration when the valence electrons are removed from each of the elements listed in the chart? A.1s22s22p63s2

B.1s22s22p6

C.1s22s2

D.1s22s22p63s1

A. 1s²2s²

B. 1s²

C. 1s²

D. 1s²2s²2p⁶

Explanation:

The valency electron is the outer electron of an element. The valency electron resides in the outermost region of the shell.

Using the general configuration for the first 20 elements 2 8 8 2 the valency electrons can be identified.

A. 1s²2s²2p⁶3s² . The valency electron here are 2p⁶ and 3s² . Removing the valency electron we have 1s²2s²

B. 1s² 2s² 2p⁶. After removing the valency electron the configuration will be 1s².

C.1s²2s². After removing the valency electron the configuration will be 1s²

D.1s²2s²2p⁶3s¹. Removing the valency electron the electron configuration will be 1s²2s²2p⁶

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

the correct answer to this question is 2
