Helium has the atomic number 2 and is the second most abundant substance in the universe.
The atomic number of Helium is 2 because there are 2 protons and 2 electrons.
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
The atomic number of an atom is determined by the number of protons it has.
The atomic number of an atom is the number of protons in its nucleus.
The number of protons is the atomic number.
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.

The atomic number of an atom is its number of protons. For instance, a hydrogen atom has an atomic number of one, meaning there is one proton in one hydrogen atom. Also, as there are the same number of protons as there are electrons in a neutral atom, the atomic number can also be thought of as the number of electrons in an atom, as long as the atom's neutral.
The atomic number of an atom is determined by the number of protons it has.
The atomic number of an atom is the number of protons in its nucleus.
The atomic number of an atom is the number of protons in its nucleus.
Atomic number is the number of protons in a neutral atom
The atomic number of an atom is equivalent to the number of protons in its nucleus.
An atom's atomic number is the number of protons within the single atom of an element
The number of protons is the atomic number.
