Protium is the lightest and most common isotope of hydrogen.
The atomic number (Z) of hydrogen is 1, meaning it has 1 proton.
Protium specifically has a mass number (A) of 1.
The number of neutrons (N) in an atom is calculated using the formula:
$N = A - Z$
For protium:
Substituting these values into the formula:
$N = 1 - 1 = 0$
Therefore, protium contains 0 neutrons.
Protium, the common isotope of hydrogen ($^1$H), has one proton and zero neutrons.
