What Used to find the number of neutrons?
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
Where do you find the isotopes in an atom?
The isotope of an atom is dependant on the number of neutrons in the atom's nucleus eg normal carbon has 6 neutrons and 6 protons but the isotope of carbon has 8 neutrons and 6 protons
What particles make up the mass of an atom?
The number of protons
How do you find the mass number given the proton electrons and atomic number but not the neutrons?
The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.
How do yo find an atoms mass number?
Mass number is the number of protons and neutrons in the nucleus of atom.
How do you find the neutrons for an atom?
Neutrons = Mass number - Number of Protons
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
How do you find out how many neutrons a atom has?
Mass number = Atomic number (or number of protons) + Number of neutrons
What Used to find the number of neutrons?
To find the number of neutrons in an atom you subtract the atomic mass fromthe mass number
How do you figures out how many neutrons are in an an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
Where do you find the isotopes in an atom?
The isotope of an atom is dependant on the number of neutrons in the atom's nucleus eg normal carbon has 6 neutrons and 6 protons but the isotope of carbon has 8 neutrons and 6 protons
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.

What particles make up the mass of an atom?
The number of protons
How do you find the number of neutrons in an atom if that number is not told to you?
if you arent given the atomic numbert for an element - where could you find it?
