2 Facts

2.1 Interesting Facts

At room temperature Sodium metal is very soft as it can be chopped down into pieces with butter knife.
The most common compound of Sodium is NaCl (Salt).

Zinc metal found (obtain) in many forms like granules, foil, dust and in a powder form.
After iron, Zinc metal the second most abundant element in the earth crust.

3 Uses

3.1 Uses & Benefits

In some nuclear reactors sodium is used as a heat exchanger.
Compound of Sodium metals called Salt (Sodium chloride) is used in Food.

It has corrosion resistance and hence it is used to plate other metals.
Its alloys are very useful; Nichrome alloy is used in the hot coil of toasters and electric oven.
