The reason for similar properties among the elements is due to the resemblance in the
electronic configuration of all the elements of a family.
For example :- Each element of Alkali metals family has 1 electron in their outermost shell.
Hence, they all have similar properties
similar chemical properties and characteristics
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
similar chemical properties and characteristics
They all have similar chemical properties.
Elements in the same group have similar electronic configurations. For example, all elements in Group 1 contain 1 unpaired electron located in an S orbital. It's the electronic configuration of atoms (and to a lesser degree, their size and charge) which dictate their chemical properties. Nuclear properties, on the other hand are dictated largely by the atoms size and number of protons and neutrons. Chemists, for the most part, aren't interested in these.
similar chemical properties and characteristics
Elements from a family have similar chemical properties.
Both elements, sodium (Na) and potassium (K) lie in the Group 1 column of the Periodic Table , which contains the members of the Alkali Metals family. Members within a family, or column, of elements tend to have similar chemical properties.
They have similar chemical properties.
similar chemical properties and characteristics
The chemical elements in a group have similar properties.
Elements with similar properties occur within the groups(columns) on the periodic table.Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.

Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
