Question

five similarities between alkali metals and halogens ​

Answer 1

Answer:

1. Both group form ionic compound but only Halogens for covalent bonds.

2. The Alkali metals have low densities while the Halogens have high densities.

3. The melting point and boiling point patterns are opposite for the Halogens it increases whereas for the Alkali metals it decreases.

I know only three...

Answer 2

Explanation:

1. Alkali metals and halogens are soft and reactive metals.
2. In order to form stable ions, they need to lose or gain one electron.
3. They both react with one other to form salts.
4. They follow the same trends of ionisation energy and density.
5. And the same trend of electronegativity is observed in them.
