The element it is hydrogen has 1 proton, helium 2, by changing protons you change what element it is.
mass
The number of protons in an atom's nucleus determines its chemical identity.
Number of protons or the atomic number of an atom determines what is the element.
The number of Protons in the nucleus determines the atom's Atomic number.
The mass number is the sum of neutrons and protons in the nucleus of an isotope.
The number of protons in each nucleus of an atom of the element.
The number of protons.
Is the number of protons in an atom determines its atomic number
The number of protons in an atom's nucleus determines its chemical identity.
The number of protons in the nucleus determines the identity of the element.
The number of protons.
Its atomic number. In other words the number of positive protons in the nucleus of each atom and the number of negative electrons surrounding the nucleus of each atom.
Number of protons or the atomic number of an atom determines what is the element.
The number of Protons in the nucleus determines the atom's Atomic number.
The atomic number, which is the number of protons in the nucleus, determines what kind of atom it is.
The number of protons in the nucleus of the atom.
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
