Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, contribute very little to the overall mass of atoms.Atoms and Isotopes Atoms of the same element have the same number of protons. All copper atoms have 29 protons. All helium atoms ...
c. neutrons and electrons. d. protons and electrons. Atomic structure: All atoms, as you might be aware, are composed of protons, neutrons, and electrons. Protons and neutrons make up the nucleus of the atom, and electrons ...
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the num...
All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus. Answer and Explanation: Learn more about this topic: ...
Electrons (+ and -), Protons, Neutrons, Mesotrons and Cosmic Rays
Some of the most common subatomic particles are photons, protons, electrons, neutrons, neutrino, anti-neutrino, and postiron. Each of these has its own purpose. For instance, photons are the packets of energy in electromagnetic radiation. Another is that a neutron is part of most ...
