It depends on what atom it is...
If it is a Hydrogen atom, it is 1
If it is a Helium atom, it is 2

Find the element you want on the Periodic Table of Elements, and there should be two numbers by that element. The smaller of the two numbers tells you the number of protons that the element has.
The atomic number is equal to the number of protons in an atom's nucleus.
The atomic number of an atom is equivalent to the number of protons in the nucleus of the atom.
The mass number is used to calculate the number of protons and neutrons in an atom. It is the sum of the protons and neutrons in the nucleus of an atom.
The number of protons in the atom's nucleus determines the element that the atom belongs to. This number is known as the atomic number and is unique to each element. By identifying the number of protons in an atom, we can determine its elemental identity.
number of protons in their nucleus.
The number of protons in an atom's nucleus is the Atomic number.
The number of protons in an atom's nucleus determines its chemical identity.
The number of protons in a nucleus depends on which element it is. ( The number of protons is the decider as to which element it is. ) The number of electrons in an atom is the same as the number of protons in the nucleus, but none of the electrons are in the nucleus. Rather, they orbit around the nucleus like planets round a star.
The number of protons in the atomic nucleus is equal to atomic number.
The atomic number is equal to the number of protons in an atom's nucleus.
The atomic number of silver is 47, which means it has 47 protons in its nucleus.
The number of protons in the nucleus of an atom.
The number of protons in the nucleus is the same as the atomic number.
The number of protons in an elements nucleus is the same number at the atomic number.
A nucleus contain protons and neutrons. A nucleus can hold more protons - the number is equal to atomic number.
atomic number is the number of protons
The number of protons.
