How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
Helium with two protons and two neutrons has a atomic number of what?
Helium with two protons and two neutrons has an atomic number of 2, as the atomic number corresponds to the number of protons in an atom.
What is an atom with two neutrons protons and electrons?
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.

Why is the atom of a helium atom unchanged adding one neutron to it?
The number of protons determines the element. So when neutrons are added, there is no change in the number of protons and helium atom is unchanged.
How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
What is the Mass number of helium atom that has two protons and two neutrons?
4 because the mass number equals protons plus neutrons. Which is 4.
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.
What does an atom of 2 protons 2 neutrons and 2 electrons make?
If the atom has a balanced electrical charge, then # of protons = # of electrons, so the atom has 2 protons (Helium). The vast majority of Helium atoms have 2 neutrons.
What is the atomic number o an atom that has 2 protons and 3 neutrons?
2 (helium). With 3 neutrons it would be Helium-5 which is the most unstable radioisotope of helium.
How many protons and neutrons and electrons has helium got?
Helium has 2 protons, 2 neutrons, and 2 electrons. The atomic number of helium is 2, which indicates it has 2 protons and 2 electrons in a neutral atom.
Why is proton number of an atom of an element different from the nucleon number of an atom of an element?
The difference between proton number (which is atomic number) and nucleon number, which is the number of protons and neutrons in an atom's nucleus, is the number of neutrons in the nucleus of a given nuclide. Nucleons are the components of an atomic nucleus. We know that both protons and neutrons make up an atom's nucleus. So the number of nucleons, which is the number of protons and neutrons, minus the number of protons, will equal the number of neutrons in the atomic nucleus.
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
