2. Ion - Wikipedia

   en.wikipedia.org/wiki/Ion

   An ion (/ ˈaɪ.ɒn, - ən /) [1] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons ...

   Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.

4. Chemical reaction - Wikipedia

   en.wikipedia.org/wiki/Chemical_reaction

   Chemical reaction. A thermite reaction using iron (III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake. A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [ 1 ] When chemical reactions occur, the atoms are rearranged and the ...

5. Ionization - Wikipedia

   en.wikipedia.org/wiki/Ionization

   Ionization can result from the loss of an electron after collisions with subatomic particles, collisions with other atoms, molecules, electrons, positrons, [1] protons, antiprotons [2] and ions, [3][4][5][6][7][8][9] or through the interaction with electromagnetic radiation. Heterolytic bond cleavage and heterolytic substitution reactions can ...

6. List of chemistry mnemonics - Wikipedia

   en.wikipedia.org/wiki/List_of_chemistry_mnemonics

   Cations are positively (+) charged ions while anions are negatively (−) charged. This can be remembered with the help of the following mnemonics. Cats have paws ⇔ Cations are pawsitive. [23] Ca+ion: The letter t in cation looks like a + (plus) sign. [24] An anion is a negative ion. (An egative ion ⇒ Anion). [25]
