How many particles in a hydrogen atom?

Answer 1

The most common isotope of hydrogen has one proton, and one electron.

The most common isotope of hydrogen has one proton, and one electron.

The most common isotope of hydrogen has one proton, and one electron.

The most common isotope of hydrogen has one proton, and one electron.

Answer 2

The most common isotope of hydrogen contains one each of proton and electron and no neutron per atom. This is the only stable atom with no neutrons. The second most common isotope of hydrogen, which is sometimes given the special name "deuterium", contains one each of proton, electron, and neutron. A radioactive isotope of hydrogen with the special name "tritium" contains one each of proton and electron together with two neutrons.

Answer 3

Hydrogen's atomic number is 1. Thus, it has 1 proton and 1 electron to keep it neutral. Hydrogen's most common isotope is 1H, thus an atom of hydrogen has no neutrons. That means the total number of subatomic particles in hydrogen is 2.

Answer 4

A hydrogen atom consists of one proton, one electron, and no neutrons. So, there are a total of two particles in a hydrogen atom.

Answer 5

how many particles are in the nucleus of an hydrogen atom

Answer 6

Basically two, one electron and one proton - but those are now known to be made of other particles.

Answer 7

In the most common isotope of hydrogen, only one particle; in its next most common and only other stable isotope, 2; and in its radioactive isotope, 3.

Answer 8

There is one proton and one electron in the atom of hydrogen-1 isotope.

Answer 9

1H: 1 proton and 1 electron

2H: 1 proton and 1 electron, 1 neutron

3H: 1 proton and 1 electron, 2 neutrons

Answer 10

The most common isotope of hydrogen has one proton, and one electron.
