What particles make up the mass of an atom?
The number of protons
How is electrons and mass number related?
The mass number represents the total number of protons and neutrons in an atom. Electrons have a very small mass compared to protons and neutrons, so they are usually not included in the mass number calculation. However, the mass of electrons does contribute slightly to the overall mass of an atom.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
Is atomic number the same as mass number?
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.

Where is most of the mass of an atom contain?
in the nucleus of an atom -proton and neutrons , electrons in the orbit has the negligible mass.
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.

How many electrons does an atom has?
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
Does fluorine contain 10 electrons?
No, fluorine contains 9 electrons. It has an atomic number of 9, which corresponds to the number of protons and electrons in a neutral fluorine atom.
Do protons and neutrons contain all of an atom's mass?
Excepting the mass of electrons (but this mass is very small)

What do the atomic number and the mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
