what are chemical reactions? | they occur when bonds are forned or broken causing substances to recombine into diff./new substances |
what is a compound? | is a substance that is a composed of atoms of 2 or more diff. elements that are chemically combined. |
when willatoms ateempt to become stable? | they will react and form bonds that form compound to try to become stable |
what is an ionic bond? | the attractive force between 2 ions or opposite charges. |
how do ionic bonds form? | the gain or loss in electrons. has an electrical charge! |
what is a covalent bond? | a chemical bond that shares electrons between atoms. |
