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 mass number represents the total number of protons plus neutrons.
The number of protons and electrons of the atom in a neutral state.
either mass or protons the top is the atomic number it shows how many protons the bottom number is the atomic mass also the weight
The number of protons (the same as atomic number) is specific for all isotopes.
The numbers on Mendeleev's periodic table represent the atomic number of each element, which is the number of protons in the nucleus of an atom. This number determines the element's identity and its placement in the periodic table.
The atomic mass number represents the total number of protons and neutrons in an atom's nucleus. It does not include the electrons because their mass is negligible compared to protons and neutrons.
The are two isotopes having a different number of neutrons but the same number of protons.
Atomic numbers represent the number of protons in an atom's nucleus. It also defines the element, as each element has a unique atomic number.
