Why helium is an element?

Helium is an element because it contains only one atom in its simplest form.


What is the mass of a single atom of helium?

The atomic mass of Helium is 4.002602. The atomic mass is the combined number of protons and neutrons in the atom.


How many electrons and prtons are in Helium?

Helium is a non metal element. There are 2 electrons in a single atom.


After a single subatomic particle is removed from an atom of helium the helium atom becomes an atom of hydrogen What subatomic particle was removed?

A single proton was most likely removed from the helium atom to result in an atom of hydrogen. Helium typically has two protons, so removing one proton would leave one, transforming it into hydrogen, which has one proton.


Is helium atom an aersol?

No, a helium atom is not an aerosol. An aerosol is a suspension of fine solid particles or liquid droplets in a gas. Helium, on the other hand, is a noble gas that exists as a single atom and is not a suspension of particles in a gas.


How many electrons shells does a helium atom have?

The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.


Is helium a single atomdiatomic moleculesmolecules formula unit?

Helium is a single atom element. It exists as individual atoms and does not form diatomic molecules, molecules, or formula units.


What does the mass number in helium represent?

The mass number in helium represents the total number of protons and neutrons in the nucleus of a helium atom. It is used to determine the mass of the atom and differentiate between different isotopes of helium.


How many electrons does an atom of helium have atomic?

Helium atom has 2 electrons.


How many electrons does heliuim have?

Helium is a non metal element. There are 4 electrons in a single atom.


Is helium element or compound?

Helium is an element. It is a noble gas with the atomic number 2 and is the second lightest element in the periodic table. Helium exists as single atoms and does not form compounds with other elements.


Element. All helium atoms have 2 protons. What is the atomic number of helium?

The only atom that contains one proton is the hydrogen atom, also called protium. It is neutrally charged with a single proton at its nucleus, and a single electron orbiting. It is possible that you are asking about the isotope of hydrogen called tritium. Tritium is a radioactive isotope of hydrogen that contains a single proton and two neutrons.
