An atom contains protons, neutrons, andelectrons. The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively charged electrons are attracted to the positively charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth...
Structure of Atoms Three main particles form every atom. Protons and neutrons cluster in the nucleus at the center of the atom. Electrons form a spinning cloud around the nucleus. Protons and neutrons make up the mass of atoms. Electrons, miniscule compared to the protons and neutrons, ...
Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The heavier theatom, the more protons (andneutrons) it contains. Hydrogen, which is the lightest element, has a nucleus made from a single proton. The heaviest element in the Periodic Table, which ...

A stable subatomic particle that has a positive electric charge and is part of the nucleus of an atom. Its charge is opposite to that of an electron but is equal in magnitude. A proton's mass is 1,836 times that of an electron. See more atatom. ...
Protons and neutrons make up the nucleus and electrons orbit them in a cloud.Answer and Explanation: The mass number is not the number of protons. The mass number is the number of protons added to the number of neutrons. The mass number can be found......
