metallic nature increases as one moves down a group


The metallic character of elements depends on atomic size and nuclear charge.
greater the atomic size, the farther the outermost orbit so nuclear pull exerted on it is less and the atom can lose electrons easily thus becoming metallic.
the greater the nuclear charge more the nuclear pull which makes it difficult to lose electrons.
on moving down a group the atomic size increases and the nuclear charge also increases, but the increased atomic size overcomes the nuclear charge and is more effective and thus tendency to lose electrons easily increases .
