actually it never changes as in 16 the group all the elements have 4 valence electrons in outermost shell so they can neither accept nor lose the electns
The metals have tendency to lose electrons. The elements of group-1,2 and 13 have tendency to form cations.
Barium (Ba) is located in Group 2 of the periodic table, which is known as the alkaline earth metals. It has two valence electrons in its outermost shell. These valence electrons are responsible for Barium's chemical properties and its tendency to form compounds.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
the vertical column is called group in the periodic table.

Bromine has the greatest tendency to attract electrons among the elements listed. This is because it is a halogen and located in group 17 of the periodic table, meaning it has a high electron affinity and tends to gain electrons to achieve a stable electron configuration.

Though the no. of valence electrons remain same in a group,but the distance between the nucleus and outermost shell increases as we move down the group and hence lesser energy is required to release the valence electron.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
It is easier to take electrons away from chlorine because it is in Group 17 of the periodic table with a higher electronegativity value compared to calcium in Group 2. Chlorine has a greater tendency to gain electrons to achieve a stable electron configuration.
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
Elements with high electronegativities are typically found in Group 17, the halogens, and in Group 16, the chalcogens, of the periodic table. These elements have a tendency to attract electrons towards themselves in a chemical bond.
Electronegativity is the tendency of an atom in a compound to attract electrons towards itself. It is a measure of an atom's ability to form bonds with other atoms by attracting shared electrons. Electronegativity values range from 0 to 4. Electronegativity increases from left to right across a period and decreases down a group on the periodic table.
