Close; Mass # is the number of protons + the number of neutrons.
Not completely, the Atomic Mass also includes the number of neutrons and the mass equivalent of the binding energy.
Protons does determine atomic number. atomic number equals to protons. how many protons in a single atom.
No, the atomic number tells you the number of protons. The mass number tells you the number of nucleons (protons + neutrons).
Yes, these numbers are equal.
The atomic number is the number of protons that the element has.
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
It depends on what atom it is...If it is a Hydrogen atom, it is 1If 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.
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
The atomic number is the number of protons that the element has.
The Atomic number tells you the number of protons in the nucleus of atoms of that element.
That would be the Atomic number. It tells you how many protons are contained in the nucleus of an atom. No two elements could share this number.
The number of protons is also the same as the atomic number.
An elements atomic number is important because it tells you how many protons are in the nucleus of the atom, and how many electrons are orbiting the nucleus in the ground state.

Its atomic number.
atomic number
The atomic number tells you the number of protons in the nucleus of an atom of the associated element.
The atomic number refers to how many protons in the nucleus and thus how many electrons are in orbit.
