Introduction to Hydrogen

Give the gene...

Question

Give the general group study of hydrogen with reference to

(i) valence electrons (ii) burning

(iii) reducing power.

Open in App

Solution

Hydrogen
The atomic number is 1
The number of electron = 1
The number of protons = 1
The valency = +1
Being electronegative ( electron deficient ) it is a good reducing agent. it forms dihydrogen oxide also know as water hydrogen burns with a pop sound.
