List the energy levels for the orbital configuration of vanadium (v) atomic number 23.

n=1,2,3,4

Explanation:

The electronic configuration of vandanium is

1s2 2s2 2p6 3s2 3p6 3d3 4s2

There are two electrons in n=1, eight electrons in n=2, eleven electrons in n=3 and two electrons in n=4

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
