4 protons and about 5 neutrons
Each atom has a unique combination of protons, neutrons, and electrons.
Protons: 10 Neutrons: 10
"Used" is the wrong term to be used in this case. An atom is MADE up of protons,neutrons and electrons. Also, the number of protons or neutrons present in an atom depends on which atom is it or of which element it is.
An oxygen atom has 8 protons and usually 8 neutrons, resulting in an atomic mass of 16.
An atom of potassium has 19 protons, 19 electrons, and typically 20 neutrons.
The atomic weight minus the number of protons = the atom's neutrons.
14 protons
17 Protons 18 Neutrons
Carbon 12 has 6 protons and 6 neutrons.
4 protons 4 electrons 5 neutrons
The phosphorus atom has 15 protons and electrons and 16 neutrons.
it depends on what type of atom you are analyzing
