Group 2 elements or alkaline earth metals.
A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
The elements in the last column of the periodic table, known as the noble gases, are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). These elements are gases at room temperature and have full outer electron shells, making them stable and unreactive.
First off, there is no "salt" on the periodic table of the elements. Salt is a compound. However, you may be talking about "sodium". If that's the case, sodium is NOT in the same column as oxygen in the periodic table. Sodium is in the first column while oxygen is in the sixteenth column.
a family is a column of elements a period is a row of elements
The group in the second column of the periodic table is Group 2, also known as the alkaline earth metals. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium.
Alkaline earth metals are placed in second column. The elements have 2 valence electrons.

A group in the periodic table is a column of elements that share similar chemical properties due to having the same number of electrons in their outer energy level. Groups are vertical columns and are numbered from 1 to 18.
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
