Subtract the number of protons from the elemental mass number for the isotope of the element given to find the number of neutrons.
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
Electrons, protons, and nuetrons. electrons are outside the nucleus, and protons and nuetrons are inside the nucleus.
In the nucleus.
mass number = protons + nuetrons
26 nuetrons, 22 electrons, and 22 protons
19 protons,21 neutrons
In the nucleas
They are colourless
protons and neutrons
Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons.
there are 12 protons in an atom of magnesium:-)
