The atomic number is...an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines the place of the element in the periodic table...and the mass number is...an integer that approximates the mass of an isotope and designates the number of nucleons in the nucleus.
an atomic number is a number that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and thats what determines where it goes on the periodic table. Well on the other hand the mass number that represents the mass of an isotope and designates the number of nucleons in the nucleus.
The atomic number is a number by which the element is ordered in the periodic table. It is also how the elements are grouped. The mass number is how much neutrons there is in the atom.
The atomic number is the number of protons in the nucleus. The mass number is the number closest to the atomic weight of an atom. It is also the amount of neucleons in the nucleus. Wow, we learn something new every day.
Well the atomic # represents the number of electrons that normally surround the nucleus, or the # of protons or positively charges in a given amount. The mass # represents the integer nearest value to the atomic weight of an atom and therew are an equal amount of neucleons in the nucleus of the atom. So the atomic # is the electrons around the nucleus and the mass # is the nucleons in the nucleus.
