An Atom
The Mg atom has more electron than the Mg+2 ion.
Sr
NO!!!! Mg( magnesium is an ATOM. However, Mg^(2+) is an ION ( cation). NB When a neutrally charged an element is an ATOM. When its gains or loses electrons it becomes an ION.

Magnesium is in the s block. It has 24 protons in a atom.

This is about magnesium element. Mg atom contains 12 protons.

Mg2+
There are 9 atoms present in one molecule of Mg(NO3)2.
Mg. I is a non-metal and Si and Ge are metalloids.
Mg is the symbol for the element magnesium and could be used to represent a neutral atom of magnesium. Mg2- does not occur, but Mg2+ does, and is the symbol of a magnesium ion, which is a magnesium atom that has lost two electrons.
well Mg is an element ( I Magnesium) and O is oxygen hence MgO is definitely a molecule not an atom ...

A neutral magnesium atom has 12 protons ans 12 electrons.
