The atoms of the elements in the same group have the same number of valence electrons.
This means that they react with other elements in a similar way.
For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil.
Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
same amount of charge
number of valence electrons
They are the same
The Periodic Table of Elements
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
number of valence electrons
Such atoms belong to a group in the periodic table of elements.

The Periodic Table of Elements
they are all part of the Periodic Table:)
An atom's "group" is its column position in the Periodic Table of the Elements. Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level.
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
Only chemical elements are placed in the periodic table; cations are positive charged atoms.
they are both in the group 14 on the periodic table of elements
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
number of valence electrons
Such atoms belong to a group in the periodic table of elements.
All the Group 14 elements has 4 electrons in its outer energy level.
