The Mass Number.
what is the sum of protons and neutrons??
mass number
They both have a weight of one.
Boron has 5 protons and 5 electrons Boron has two stable isotopes, one with 5 neutrons and 6 neutrons.
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.

Mass number!:)
A silver atom has 47 protons and 61 neutrons.
the nucleus
They both have a weight of one.
16 protons, 16 electons, 20 neutons
Protons and neutrons contain quarks and gluons; electron is a fundamental paticle.
They have little bit simillar mass. But there are no charge on neutrons.
Isotopes
in the nucleus of an atom
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
Boron has 5 protons and 5 electrons Boron has two stable isotopes, one with 5 neutrons and 6 neutrons.
Protons and neutrons are located in the nucleus of an atom. The protons have a positive charge, while neutrons have no charge (they are neutral). The nucleus, containing protons and neutrons, is at the center of an atom and is surrounded by electrons.
Protons and Neutons, I believe.. Because dont electrons revolve around the nucleus or something?
