Metallic character decreases from left to right in a period.

1.      Metallic character decreases from left to right in a period.

Ans.

i.                    Atoms of metals tend to lose electrons, whereas those of non – metals tend to gain them.

ii.                  In a period, as we go from left to right, atomic number increases, increasing the number of electrons and protons.

iii.                These additional electrons are placed in the same outer shell and are strongly attracted towards the positively – charged nucleus.
iv.         This strong attraction does not allow loss of electrons, causing metallic character to decrease from left to right in a period.
