Chapter 2.2 - Classification Of Matter Flashcards
Alloys
Mixture containing metals (which are hard)
Chemical species
All the particles of matter
Allotrops

Organic compound
Any compound that has carbon and hydrogen atoms (may have other types of atoms as well)
Binary compound
Composed of only 2 elements
Ion
Is a charged atom or group of atoms
Ionic compounds
Consist of positively and negatively charged ions held together by their opposite electrical charges
Ionic crystal lattices
A long range, symmetrical packing (ionic compounds)
Ionic bond
The attraction/bond between oppositely charged ions
Covalent bond
A shared pair of electrons that holds two atoms together
Molecule
A neutral group of covalently bonded atoms
Molecular compounds
Compounds consisting of molecules
Acid
A compound that has one or more H+ ions bonded to an anion (HCl, H2SO4, H3PO4)
Base
Hydroxides (OH - NaOH, Ca(OH)2, Al(OH)3)
Salt
Any ionic compound other than a hydroxide
