What is the protons neutrons and electrons of helium?

Answer 1

The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.

See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.

Answer 2

Helium has two protons. If the atom is neutral, it will therefore also have two electrons. The number of neutrons, of course, depend on the isotope; the most common isotope, helium-4, has two neutrons. Another helium isotope, helium-3, has only 1 neutron.

Answer 3

Answer

Helium 3 isotope: 2 protons, 1 neutron, 2 electrons

Helium 4 isotope: 2 protons, 2 neutrons, 2 electrons

Also, for plato, the answer is: two protons, two electrons, and two neutrons

Answer 4

Helium has 2 protons, 2 neutrons and two electrons.

Answer 5

2 each for the most stable isotope of Helium (He-4)

Answer 6

protons are 2 electrons are 2 and neutrons are 2

Answer 7

Helium 3 has 2 protons and electrons and 1 neutron.
Helium 4 has 2 protons and electrons and 2 neutrons.

Answer 8

Helium has 2 protons, 2 neutrons, and 2 electrons.

Answer 9

2 protons, 2 electrons and 2 neutrons
