Oxygen has:
8 neutrons
8 protons
(8 electrons)
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
protons and nuetrons are equal to no. of electrons present in atom
19 protons,21 neutrons
26 nuetrons, 22 electrons, and 22 protons
Neutral oxygen has 8 protons and 8 electrons. It's most common isotope is 16O. Thus oxygen usually has 16 - 8 = 8 neutrons.
there are 12 protons in an atom of magnesium:-)
2 of each
5 protons 8 neutrons try it
8 neutrons
12 , 12 , 12
An atom with 8 protons will have an atomic number of 8. Checking the periodic table, we see this element is oxygen. The isotope of oxygen with 8 neutrons is 16O.
20 protons, 20 electrons, and usually 20 neutrons
