Answer:
Atoms of metals tend to lose electrons, whereas those of non – metals tend to gain them.
In a period, as we go from left to right, atomic number increases, increasing the number of electrons and protons.
These additional electrons are placed in the same outer shell and are strongly attracted towards the positively – charged nucleus.
This strong attraction does not allow the loss of electrons, causing the metallic character to decrease from left to right in a period.
This strong attraction does not allow the loss of electrons, causing the metallic character to decrease from left to right in a period.
In case of the group, when we down the group the size of an atom of elements increases.
The strength of the bond is inversely proportional to the size of an atom.
Hence, because of larger size, the strength of bond decreases down the group.
