QUESTION:
Group the following electron configurations in pairs that would represent similar chemical properties of their atoms: (a) 1s 2 2s 2 2p5 (b) 1s 2 2s 1 (c) 1s 2 2s 2 2p6 (d) 1s 2 2s 2 2p6 3s 2 3p5 (e) 1s 2 2s 2 2p6 3s 2 3p6 4s 1 (f) 1s 2 2s 2 2p6 3s 2 3p6 4s 2 3d104p6
ANSWER:Step 1 of 4
Elements belonging to the same group will show similar chemical property. This is identified by the subshell in which the last electron enters.
If two elements have the same number of electrons in the valence subshell they belong to same group and show similar chemical property.
