A element has 12 electrons. Is it a metal or non-metal, what type of bonds does it form and what is its electronic configuration when it forms bonds?

An element with an atomic number 12 has 12 electrons. The
electronic configuration is 1s2, 2s2, 2p6, 3s2. Now this element has two electrons in excess of
the closest Nobel gas. The electrons in the 3rd shell take part in all chemical reactions of the
element.

The element has metallic
properties.

The ions formed by the atoms of the element are
positively charged and they have two positive charges as two electrons are lost when it reacts
with other elements. If the element has a symbol A, the ions are denoted as
A2+.

It forms ionic bonds with other
elements.
