the answer is 2,8,1
One Proton One electron zero neutrons
Neutrons = Mass number (Se-80) minus Atom (or proton 34Se) number (34) = 80-34 = 46 neutrons
Hydrogen only has one proton. A Hydrogen-3 atom contains one proton and 2 nuetrons. This is because atoms of a certain element can vary in the amount of nuetrons. The're called isotopes.
Hydrogen contains 1 proton and usually no neutrons. Though this depends on the isotope. A small percentage of hydrogen contains 1 proton and 1 neutron and an even smaller amount has 1 proton and 2 neutrons. This last variety is radioactive.
This is 100% dependant on the element and the isotope of the element. Not every nucleus is the same.
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
there are 12 nuetrons in an atom of magnesium
im eleven and i know the answer the answer is 18 nuetrons
hey perhaps your question is incomplete. but if your question is what is protons and neutron relationship then a neutron plus a positive charge having mass equal to electron mass then proton forms.
there are 8 neutrons in every oxygen atom so times it by 16 is actually 128
protons and nuetrons are equal to no. of electrons present in atom
26 nuetrons, 22 electrons, and 22 protons
