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 ( ...

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

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

As you go down the group: the metals become more reactive. This is due to ... -the melting and boiling points of the metals decrease. Other general ...

The boiling points of the elements in Group 7 tend to increase as you go down the group because the molecules get larger and the intermolecular forces get ...

Melting point increases as it takes more energy to overcome the electrostatic forces of attraction between positive ions and delocalised electrons.

This causes the melting point of the metals to reduce as you go down the group. For the same reason the first and second ionisation energies also decrease going ...

The boiling point of the halogens increases as you go down the group. The halogens exist as diatomic molecules, with both atoms sharing an electron to ...

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 you go down the group, ionisation energy decreases because there are more electron shells and shielding increases, therefore the outer electron is further ...
