What is an atom that has more protons than electrons? Atoms: Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...

Nucleosynthesis is the creation of new atomic nuclei, the centers of atoms that are made up of protons and neutrons. Nucleosynthesis first occurred within a few minutes of theBig Bang. At that time, a quark-gluonplasma, a soup of particles known asquarks and gluons, condensed into protons an...
Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). Positron An elementary particle having the same mass and magnitude of charge as an electron but exhibiting a positive charge; the antiparticle...
