How many neutrons are in helium?
A helium atom typically has two neutrons. This gives helium a total of four particles in its nucleus (two protons and two neutrons), which contributes to its atomic mass of approximately 4 atomic mass units.
How many protons neutrons and electrons does the inert gas helium have?
2 protons, 2 electrons He-3 isotope has 1 neutron He-4 isotope has 2 neutrons
What is the superscript 4 for helium?
4He or He4. 4 stands for the mass number of Helium Mass number = number of protons + number of neutrons Since the atomic number or number of protons in helium is 2, the number of neutrons in He-4 is also 2.
This atom is a of helium -4?
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
What is the number of protons and neutrons in a helium isotope with an atomic mass of 6?
A helium isotope with an atomic mass of 6 would have 2 protons, as all helium atoms have 2 protons. To find the number of neutrons, subtract the number of protons from the atomic mass. So for this isotope, 6 (atomic mass) - 2 (protons) = 4 neutrons.
How many nuetrons does helium have?
Helium has two protons and two neutrons (and two electrons).
How many neutral neutrons does helium have in its nucleus?
He-4 isotope has 2 neutrons.

What makes the element 'Helium'?
The isotope helium-3 contain 2 protons and 1 neutron. The isotope helium-4 contain 2 protons and 2 neutrons.

How many nuetrons are in helium?
1 neutron in He-3 isotope. 2 neutrons in He-4 isotope (most stable)
What is helium gas mean?
Helium is a gaseous element at STP and has 2 protons, 2 electrons. He-3 isotope has 1 neutron whereas He-4 isotope has 2 neutrons.
Protons electrons and neutrons contained in helium?
2 each in the case of He-4 isotope.
What is the number of protons neutrons and electrons for Helium?
protrons=2 electrons=2 neutrons=2
