As you go down group 7, the halogens become less reactive. This is because: Decreasing reactivity, - Atomic radius increases. - Nuclear charge increases, so the nuclear attraction on the outer electrons are stronger. - Electron Shielding increases and outweighs the nuclear ...

The number of electrons which each atom can contribute to the delocalised “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium to magnesium to aluminium.
Web8 okt. 2024 · The melting and boiling points of Boron are very high as compared to those of the other elements of the group. This is due to network structure of Boron. Gallium has the lowest melting point in this group due to the weak binding forces in the system in which Ga exist as Ga 2. The elements of this group exhibit high boiling points which steadily ... WebAnswer (1 of 6): The melting point of period three elements increases from sodium to silicon and decreases from silicon to argon. In general, melting point increases across a period up to group 14, then decreases from group 14 to group 18. The melting point of group 1 and 2 metals decreases down...
