Answer:
The element is Magnesium.
Explanation:
On the periodic table, elements are arranged based on atomic number and chemical similarity.
- A group on the periodic table is a vertical column that places elements with very similar chemical characteristics together. For instance, the elements in group 18 are all gases (this group is named the Noble Gases group).
- A period on the periodic table is a horizontal row that places elements that show periodic trends together. They also have very similar characteristics (same amount of subshells that house electrons).
If we look at the periodic table, we will notice that there are eighteen groups and seven periods. And, we can also see that the groups are vertical while the periods are horizontal.
Therefore, if we count two across and three down, we will see the element Mg - atomic number 12. Mg is the element symbol, not the name, so we can look and see that the name of the element is Magnesium.
