[Ar] 3d3 4s2
Or, expanded:
1s2 2s2 2p6 3s2 3p6 3d3 4s2
The bipositive ion of strontium takes the electron configuration of xenon.
Atoms can have as many electron shells as they need. The first electron shell can only contain 2 electrons but the rest can contain 8. Electron arrangement patterns down a group : the # of complete electrons shells increases by 1. The # of group is the same as the # of electrons in the outer shell. (ex. Group 2 there will be 2 electrons in the outer shell) Electron arrangement patterns across a period : the # of complete electron shells stays the same. The # of electrons increases by 1 each time. When a new period starts, that's when a new shell is added. Hope this was helpful :)
The electric field is stronger near the electron and becomes weaker as the distance from the electron increases.

An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
