Hydrogen/Electrons per shell

What are the number of neutrons in hydrogen?

For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons.

How many protons neutrons and electrons are in a hydrogen 3 atom?

Tritium is an isotope of hydrogen that is composed of one proton, two neutrons, and one electron. The symbol for tritium is 3H. The atomic number of tritium is 1 and the atomic mass of tritium is 3.

### How many electrons are in each shell of hydrogen?

1 electron
Hydrogen has 1 electron in the first shell (so one valence electron). Helium has 2 electrons — both in the first shell (so two valence electrons). Lithium has 3 electrons — 2 in the first shell, and 1 in the second shell (so one valence electron).

Does deuterium have neutrons?

The nucleus of deuterium, called a deuteron, contains one proton and one neutron (mass number = 2), whereas the far more common hydrogen isotope, protium, has no neutrons in the nucleus. The most common use for deuterium is in nuclear resonance spectroscopy.

What is the number of neutrons in hydrogen?

Most hydrogen atoms have no neutron. However, rare isotopes of hydrogen, called deuterium and tritium , have one and two neutrons each, respectively.

## What is the number of electrons in hydrogen?

Hydrogen can have any number of electrons and still be hydrogen. To be electrically neutral, it must have one electron. With two electrons, as H-, it exists as the hydride ion. With no electrons, as a bare nucleus, it exists as the H+ ion.

How many protons does hydrogen have?

Therefore, a hydrogen molecule has two protons, and 2 electrons (which form the bond between hydrogen atoms). In acidic solutions, hydrogen is found as the H+ ion (1 proton, 0 electrons), and is sequestered by water molecules to form the hydronium ion (H3O+).

What atom has 6 protons 6 neutrons and 6 electrons?

all isotopes of carbon atoms have 6 electrons and 6 protons, which is why the atomic number of carbon is 6. a carbon-12 atom has 6 protons, 6 neutrons, and 6 electrons, so its mass number is 12 and its atomic number is 6.
