Ions

Crystal Lattice

3-D arrangement of particles in a solid ionic compound

How are positive and negative ions formed?

Ions are formed when an atome either loses or gains an electron. A positive ion is formed when an element, typically a metal loses 1 or more electrons. A negative ion is formed when an element, typically a nonmetal gains 1 or more electrons

how does electron configuration relate to ion information

Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.

Give two examples of ionic compounds

NaCl, CaF2

metallic bond

a bond between two metals

Cation

a positively charged ion

Monatomic Ion

an ion consisting of a single element

Electrolyte

an ionic compound is solution that can conduct electricity

Ionic Bond

chemical bond that forms from a transfer of electrons

delocalized electron

electrons that are freely move from atom to atom throughout a metal

Lattice Energy

energy required to separate one mole of the ions of an ionic compound

Chemical Bond

force that holds two atoms together

Anion

negatively charged ion

oxidation number

the charge of an ion

what is a chemical bond

the force that holds two atoms together

Formula Unit

the lowest possible ratio of elements in an ionic compound (ex: MgO, not Mg2O2)

Polyatomic Ion

two or more atoms that act as a single unit and carry a charge

Ionic Compound

when a metal donates one or more electrons to a nonmetal
