Correct answer
A3
Step-by-step explanation
Hydrogen has three isotopes
(A) Protium () has 0 neutron.
(B) Deutrium () has 1 neutrons.
(C) Tritium () has 2 neutrons.
Total number of neutrons in three
isotopes of hydrogen = 0 + 1 + 2 = 3
(A) Protium () has 0 neutron.
(B) Deutrium () has 1 neutrons.
(C) Tritium () has 2 neutrons.
Total number of neutrons in three
isotopes of hydrogen = 0 + 1 + 2 = 3
