The life span of atomic hydrogen is :
A
Fraction of one sec.
B
One year
C
One hour
D
One day
Detailed Solution
Atomic hydrogen (free H atoms) is produced by passing hydrogen through an electric arc or by dissociating $H_2$ at very high temperature.
H atoms are very reactive and quickly recombine to form $H_2$ molecules, releasing a large amount of energy ($H + H \rightarrow H_2$, about 436 kJ/mol). This is used in the atomic hydrogen torch.
So the life span of atomic hydrogen is only a fraction of a second.
