How atoms become ionized Radioactive decay Splitting the atom Additional resources Bibliography Atoms are the basis of the elements. There are 118 known elements in the Periodic Table, 92 of which occur naturally, and each is based on a different atom. The word "atom" comes from the ...
What's so good about ions? They're very important in many chemical reactions. For example, ordinary table salt (which has the chemical name sodium chloride) is made when ions of sodium join together with ions made from chlorine (which are called chloride ions). A sodium ion is made when...
Neutral atoms are relatively stable because of their lack of charge. Ionization refers to the process of neutral atoms gaining or losing electrons to become ions. Ions are rarely separate from each other; they are attracted to ions of the opposite charge. Compounds Chemical compounds contain at l...
Ions are atoms (or groups of atoms) with an electrostatic charge.

When an atom loses an electron to become a cation (e.g.Be -> Be2+,Li -> Li+),the atomic radius,AKA size,decreases - this makes sense because now the proton:electron ratio has increased so the 'pull' on each electron is stronger.The reverse applies for atom -> anion (F -> F-)...
It is the smallest constituent unit of matter that possess the properties of the chemical element. Atoms don’t exist independently, instead, they form ions and molecules which further combine in large numbers to form matter that we see, feel and touch. ...
