Refer to the Periodic Table to find an element's atomic number. This gives the proton number of that element, as well as the number of electrons (assuming the atom is neutral). For example, carbon has an atomic number of 6, which means it has six protons, and - when neutral - 6 electrons, as well.

Helium-6 has two protons and electrons and four neutrons.
Which particles determine the net charge of an atom or ion and how do you calculate that charge?
The net charge of an atom or ion is determined by the balance of protons and electrons. Protons, which have a positive charge, and electrons, which have a negative charge, contribute to the overall charge of the atom. To calculate the net charge, subtract the number of electrons from the number of protons: ( \text{Net Charge} = \text{Protons} - \text{Electrons} ). If an atom has more protons than electrons, it is positively charged (cation), while more electrons than protons result in a negative charge (anion).
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
How do you calculate proton neutrons and electrons in Na?
11 protons and 12 neutrons
How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?
Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
How you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass number?
the atomic mass number is the number of protons/electrons in an atom
How do you calculate ionic charge?
If the amount of protons and electrons are unequal than subtract the biggest minus smallest number. Ex: An atom has 4 protons and 3 electron. You subtract 4-3 to get 1. So the charge will be +!. I hope this helped.
