bonds - ionic covalent metallic

metal ions

lose electrons

nonmetal ions

gain electrons

stable electronic structure

when atoms gain or lose electrons to get a full outer shell

ionic bond

metal and nonmetal

cation

positive ion

anion

negative ion

electrostatic force

a force of attraction between opposite charges

ions high melting and boiling points

strong attraction between ions

ions conductivity

dont conduct when solid but conduct when in solution

ions solubility

many are soluble

ions structure

ionic lattice

covalent bond

pair of electrons is shared between two atoms

molecule

made up of two atoms held together by covalent bonds

compound

made up of atoms of more than 1 elements chemically joined together

simple molecular (covalent) low melting and boiling points

weak intermolecular forces

simple molecular (covalent) solubility

some are soluble

simple molecular (covalent) conductivity

most dont conduct

polymers

complex molecules made from simple molecules

giant covalent high melting and boiling points

giant lattice

allotropes

made of the same atom but have different structures

fullerene

molecules made up of carbon

metallic conductivity

delocalised electrons carry electrical charge

metallic high melting and boiling points

strong metallic bond between a positive metal ion and delocalised negative electron

metallic solubility
