hi
The outer electron in the electronic configuration give idea of the group in the Modern Periodic Table & also period.
The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.

The element Magnesium has two charges. The element Magnesium has two charges.
Shouldn't you do the homework yourself. Teach your teacher!

Germanium in the 4th period has 4 valence electrons.It has electronic configuration of 2 8 18 4.
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
The element is titanium and is in 4th period, group 4.
ns1, where n is the number of the period in which the element is present
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
Depending on the editor of the periodic table: name, symbol, atomic number, density, electron configuration, group, period, melting point, boiling point etc.
The element Mg is in the 3rd period of the periodic table.
The inert gas in Period 2 is the element Neon(Ne). Its electron configuration is 2-8.
The element Magnesium has two charges. The element Magnesium has two charges.
