As the number of electron shells increases down the group, and consequently the atomic radii get bigger, the attraction between the nuclei and outer shell ( ...

As we go down group I, the ions have larger shells and the distance between the bonding electrons and positive nucleus decreases.

Going down group 1 the period number increases. This means the number of shells increases, leading to a decrease in electrostatic attraction.

This is due to the increased number of electron shells which means the outer electron is further from the nucleus so it is more easily lost. -the melting and ...

As you go across the period, the atomic radii decreases. This is due to an increased positive charge of the nucleus (increased electronegativity) pulling the ...

Due to the size of the atoms increasing, the strength of the metallic bonds between atoms of the element decreases going down the group. This is because the sea ...

The number of electrons increases in each element going down the group, this leads to an increase in temporary dipoles which can be set up.

The melting points and boiling points of the halogens increase as you go down the group. This is because larger molecules within the same group experience ...

As the group is descended the reactions become more vigorous in nature. One contributing factor to this is the decreasing ionisation energy of group 1. Не найдено: melting | Нужно включить: melting

This is because the atomic radius increases from Florine to Iodine and electronegativity decreases from Florine to Iodine.
