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.
What else can I help you with?
Which of the has an electric charge?
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
What will an alpha particle change into when it absorbs two electrons?
When an alpha particle absorbs two electrons, it will become a helium atom. This is because an alpha particle is essentially a helium nucleus consisting of two protons and two neutrons, and by also gaining two electrons, it will form a stable helium atom with two protons, two neutrons, and two electrons.
What are the main subatomic particles located in the atom?
protons, neutrons, electrons.protons, neutrons, electrons.protons, neutrons, electrons.protons, neutrons, electrons.
Where are protons neutrons and electrons located?
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
Are gold and helium both made of subatomic particles?
Yes, both gold and helium are made of subatomic particles. Gold is composed of atoms containing protons, neutrons, and electrons, while helium is a noble gas made up of atoms with two protons, two neutrons, and two electrons.
