Title: How do I figure out the number of neutrons of an element? Post by: lfbella on Sep 8, 2012 The number of protons and electrons are the same. Therefore, I take the atomic weight, round to the nearest whole number and subtract the number of protons (atomic number) to get neutrons. Is this correct?

You Take the Atomic Number(right corner) and subtract it from the Atomic Mass. For Example, i had yttrium the atomic number was 39 and the mass was 89. the proton and electron is 39 and neutron was 50,(89-39) im 11 in 6th grade i had to learn this and yes thats right |
