2Thank You

Yogita Ingle 6 years, 3 months ago

Corrosion of some metals is an advantage-
Example: corrosion of aluminium is useful. Corrosion of Aluminium occurs when the metal is exposed to oxygen, according to the following reaction :
4 Al(s) + 3 O₂ (g) → 2 Al₂O₃(s)
Thus a protective layer of aluminium oxide is formed on the surface of the metal, which renders the metal passive and prevents its further corrosion.

How does metallic character change in moving from top to bottom in modern periodic table

Posted by Nitin Kumar 6 years, 3 months ago

CBSE > Class 10 > Science

3 answers

Suryansh Agarwal 6 years, 3 months ago

On going top to bottom in a periodic table the metallic character of elements increases. This is because the atomic radii decreases which further decreases the effective nuclear charge on valence electrons and the electrons can be lost more easily just by providing a measurable amount of energy.

Gaurav Seth 6 years, 3 months ago

Hydrogenation is the process of converting vegetable oil to vegetable ghee. During hydrogenation, vegetable oils are reacted with hydrogen gas at about 60°C. A nickel catalyst is used to speed up the reaction. The double bonds are converted to single bonds in the reaction. In this way, unsaturated fats can be made into saturated fats i.e. oil is converted into fats.
