Excepting beryllium, the others mentioned elements produce basic solutions when are dissolved in water.
by their atomic number
the periodic table has all the elments
They are only two Mercury and Bromine.
Technetium (43), Promethium (61), and all the transuranic elements are synthetic.
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
The noble gases viz., helium, neon, argon, krypton, xenon, radon
A "family" of elements means the vertical columns in the periodic table. If you look above the periodic table, there will be numbers for each row, numbered from 1 to 18. Each "family" is a column.
