when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or Atomic Mass...that is if you add protons to electrons you have your atomic mass.
What else can I help you with?
How atomic mass describes the number of protons in the nucleus of an atom?
Atomic mass is the total of the number of protons PLUS the number of neutrons.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
What particles make up the mass of an atom?
The number of protons
The number of protons and neutrons in an atom?
Depends on the atom. The atomic number will give you the number of protons. The atomic weight will give you approximately the number of protons and neutrons combined.
Which pair below describes isotopes of the same element Aan atom with 6 protons and 8 neutrons - an atom with 8 protons an 6 neutrons Ban atom with 6 protons and 6 neutrons - an atom with 6 p?
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.
How atomic mass describes the number of protons in the nucleus of an atom?
Atomic mass is the total of the number of protons PLUS the number of neutrons.
What is the sum of protons and neutrons in an atom?
Mass number!:)
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
What is the sum of protons neutrons in an atom?
Mass number = Protons+Neutrons
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
What particles make up the mass of an atom?
The number of protons
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
