The number of electrons is the same as the number of protons, which is the atomic number of the element.

How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an 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).
How do you determine the numbers of subatomic particles in an atom based on its identity?
Atomic number of a chemical element = Number of protons = Number of electrons Atomic mass of an isotope (mass number) - Number of protons = Number of neutrons
How you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
Can the mass number of an element be used to determine the number of electrons in an atom?
No. The mass number can be used, however, to determine the number of neutrons. Electrons can only be determined by knowing the atom's charge.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
What determine the atom mass?
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.
If a neutral atom has a mass of 12 amu and an atomic number of 5 determine the number of protons neutrons and electrons in the atom.?
Protons: 5 Neutrons: 7 Electrons: 5
What determine the mass and an atom?
Protons, neutrons and electrons
What is counted in an atom to determine mass number?
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
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.
What particule is used to determine the mass of an atom?
Protons, neutrons and electrons
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.
