positive charge in the atom
atomic number
Its atomic number - how many protons it has.
they represent the number of protons the element has and what is their charge
The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
The atomic number of an element also represents the number of protons in that element.
The mass number represents the total number of protons plus neutrons.
The number of protons and electrons of the atom in a neutral state.
The sum of Protons and neutrons
The atomic number of an element represents the number of protons in each atom of the element.
The atomic number represents the number of protons in the nucleusNumber of protons in nucleus.Number of electrons in the clouds around the nucleus (when not ionized).
The numbers on the periodic table represent the atomic number, which is the number of protons in an atom's nucleus. The letters represent the chemical symbol of each element.
The number of protons (the same as atomic number) is specific for all isotopes.
