The elements of the periodic table that belong to the same group (each column) have similar physical and chemical properties. This is because they have the same number of electrons in their last electronic layer.
Example of electronic configuration of elements of GROUP IA:
Hydrogen: 1s ^ 1
Lithium: 1s ^ 2 2s ^ 1
Answer:
B- The polarity of the molecules and hydrogen bonding between molecules.
