Question

Arrange the following as per the instructions given in the brackets:-​

Answer 1

1. we know that along the period from left to right the ionization energy increasing but from up to down of a group of periodic table the ionization energy decreasing.So the order is, Li>Na>K.As they are lie in a group of no.1.

2. This also is same because, around the period the electronegativity is increasing but in a group the electronegativity is decreasing due to the high number of orbital.So the order is,F>Cl>Br.

3. We also know that along the period the atomic size is decreasing but along the group from up to down the atomic size is increasing due to the high number of orbital.So the order is Na>Si>S.

4.along the period, the metallic character is same with the atomic size or the radius of a atom. show so it is increasing along the the group and decreasing along the period.So the order is K<Rb<Cs.

Hope you understand.
