How can the number of neutrons in the necleus of an atom be determined?

The number of protons in an atom gives you the elemental identity of that atom, and it represents that element's atomic number. Also in an atom, the number of protons plus the number of nuetrons gives you the atomic mass of that atom. If you have the atomic mass and the atomic number of an atom, you then subtract the atomic number from the atomic mass to get the neutron count. It's pretty simple math…

The atomic number of an atom is the same as the number of what?

It is the number of protons in the nucleus of an atom that determines its atomic number. The proton count sets the atomic number and gives each atom its chemical identity.

This neutron or electron or proton gives an atom its atomic number?

The number of protons gives the atomic number. The number of electrons are equal to the number protons unless the atom is ionized. The number of neutrons determines which isotope you have. Hope that helps

How are the mass number and the atomic number of an elment different?

How much protons are in oxygen?

A atom's atomic number gives its number of protons. Oxygen's atomic number is 8. Thus, it has 8 protons.

How many protons do lutetium have?

An element's atomic number gives its number of protons. Lutetium's atomic number is 71. Thus, it has 71 protons.

Phosphorus has an atomic mass of 31 and an atomic number of 15 the number of neutrons must be?

Mass number = no. of protons + neutrons Atomic number = no. of protons Thus (mass number - atomic number) gives you no. of neutrons. Therefore for phosphorus, the number of neutrons would be 16.

If an atom has the atomic number of 4 and the atomic mass of 9.012 how many electrons will it have?

Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
