Help me define some chemistry words please!

[From: ] [author: ] [Date: 11-11-22] [Hit: ]
Ion: Any atom or molecule having a positive or negative charge.Anion: Any atom or molecule carying a negative charge. (HO^-1, hydroxide is an example.)Dianion: Any molecule carying 2 negative charges, each on a different atom.......
the most common visible wavelengths of the spectrum (ie. light)

Sodium Hydroxide: NaOH (caustic soda, lye)

Hydrogen Peroxide: HOOH (water with an extra oxygen inserted.

Chemical decomposition: The chemical process by which an unstable substance breaks down into simpler substances.
Hydrogen Peroxide slowly decomposes into Water and Oxygen. 2 H2O2 ---> 2 H2O + O2

Hemoglobin: The protein complex in blood responsible for carrying O2 to the cells of living organisms.

Ion: Any atom or molecule having a positive or negative charge.

Anion: Any atom or molecule carying a negative charge. (HO^-1, hydroxide is an example.)

Dianion: Any molecule carying 2 negative charges, each on a different atom. (1-^O2CCO2^-1, called Oxalate, is an
example.)

Excited state: An atom or molecule in which one or more electrons are kicked up to a higher orbital or energy level.

Energy level: Any of certain fixed levels which electrons can occupy.

Oxidizer: A substance capable of raising another substance to a higher oxidation state. Oxygen, in the presence of
water, will cause Iron to rust. In this reaction Iron is oxidized from the 0 state to the +3 state, while Oxygen is
reduced from the 0 state to the -2 state. The oxidizer is usually called the oxidant, while the other substance is
called the reductant.

-
Electron- a negatively charged subatomic particle found outside the atomic nucleus; it is in all atoms.
Ground State-the lowest-energy, or most stable, state.
Ion-electrically charged atom that can be positively or negatively charged, depending on whether electrons are lost (positive) or gained (negative) by the atoms.
anion- negatively charged ion.
excited state-a higher energy state than the ground state...less stable.
