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.

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
What is atomic numbers?
Atomic numbers are the number of protons and electrons in a atom.
What are valence electrons and what do they determine?
They determine many things. They can be used to predice hybridization, determine octet, be used to assign formal charges. The simplest answer would be for a intro to chem class, they determine the number of electrons in the atom's "outer ring"
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
Does the number of electrons an atom has defines what kind of element it is?
yes
What number of an element can be used to determine the number of electrons in an atom?
The Atomic Number of an element is the same as the number of protons in the nucleus of an atom of that element and/or the number of electrons a in neutral atom of that element.
Do electrons determine what kind of element an atom is?
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
How do you determine the number of electrons inone atom of an element?
the number of electrons of an atom is the same as it's atomic number
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
How do you determine the valence electrons of aluminium?
In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
Can the mass number be used to determine the number of electrons in an atom?
The number of electrons is the same as the number of protons, which is the atomic number of the element.
Which things determine an element's electronegativity?
the number of valence electrons in the atom's outer shell how much the valence electrons are shielded from the nucleus
How can you determine the number of valence electrons in an atom?
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
How do you determine the number of electrons?
The number of electrons is equal to the number of protons in that atom. An easy way to view that is with the Bohr Model.
What number of the outer energy level of an atom helps determine which category an element belongs in?
electrons
How can you determine the number relate to the protons and electrons of an element?
Protons are positively charged, electrons are negatively charged. Each atom has the same number of electrons as protons.
