Atoms
Element
Atomic mass
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
-
Atomic number
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
-
-
-
-
a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.
Isototpes
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
-
Ions
-
-
Anions
a negatively charged ion, i.e. one that would be attracted to the anode in electrolysis.
Nucleus
the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
-
-
protons
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.
-
-
neutrons
a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
