What is the electron configuration for Ar2?

Answer 1

potassium; doing the chem homework? :) Maroulis woot.

Answer 2

The electron configuration for Ar is 1s2 2s2 2p6 3s2 3p6

Answer 3

1s^2 2s^2 2p^6 3s^2 3p^6 Note: The "^" symbol means the the following number is in the form of a superscript.

Answer 4

Argon (Ar) is a noble gas and is stable. So it does not form Ar2- anion. The hypothetical Ar2- anion will have 20electronswith the configuration[Ne]3s23p64s2

Answer 5

2p6

A=3+R=3(2P)=8

Answer 6

18
