The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the Atomic Mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.
If the atom is neutral, the number of electrons is the same as the atomic number. If the atom is an ion, the number of electrons is the atomic number minus the charge on the ion; this means negatively charged ions have more electrons than their corresponding neutral atoms and positively charge ions have fewer electrons than their corresponding neutral atoms.
because an atomic number is the same as the number of electrons in an atom (not ion)
the Atomic Mass number is the number of protons/electrons in an atom
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
the number of protons in an atom and the number of electrons in an atom

the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the atomic mass number is the number of protons/electrons in an atom
The number of electrons is the same as the number of protons or the atomic number. If the element is an ion of e.g O+2, you would take away 2 from the atomic number and if it is O-2, you would add two electrons
Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
you look at either the atomic number or the number of electrons. That's the number of protons.
you can find electrons by subtract the atomic number and atomic mass.
