Last week, we have discussed on the Common Properties of a Group (in general).
Today, let’s take a closer look at the properties of elements from 3 very important groups that examiners like to test you:
Properties of Impt Groups in Periodic Table:
Group I (Alkali Metals)
- Soft & Silvery Metals
- Low Densities & Low MPs
- Has 1 valence electron
- Forms ions with 1+ charge by giving away 1 valence electron
- Reacts vigorously with cold water to form metal hydroxide alkaline solution & hydrogen gas
- Reacts vigorously with chlorine gas to form ionic metal chlorides
Group VII (Halogens) [Read more…] about O Level Chemistry: Periodic Table & Group Trends (I, VII & 0)
