Naming and Properties of Compounds Quest

monatomic ion

singular atom with a positive or negative charge from the loss or gain of (a) valence electron(s)

polyatomic ion

contain more than one atom, but behaves like a monatomic ion

valence electron

electron in the outermost energy level

ionic bond

combination of cation and anion

binary compound

two elements

bond

forces that hold one atom to another in a compound

metallic bond

bonds between atoms in a metal; ions held together in a crystalline lattice in a “sea of mobile electrons”

ion

charged particle

ionic bond

formed when electrons are transferred between atoms

covalent bond

sharing electrons because both elements have high electronegativities

properties of metallic bonds

• high melting and boiling points

• hard

• solid when conductive

• liquid

• aqueous

• generally odorless

• insoluble

• generally solid at room temperature

properties of ionic bonds

• high melting and boiling points

• hard

• liquid

• aqueous

• generally odorless

• soluble generally solid at room temperature

properties of covalent bonds

• low melting and boiling points

• soft

• generally odorless

• in/soluble

• solid, liquid, or gas at room temperature
