What are 2 differences between ionic and covalent bonds?
Ionic - - transfers electron, creates componds, and involves a metal AND a nonmetal
Covalent - - shares electrons, creates moleucles, and involves 2 NONmetals
What is the difference between a structural and molecular formula?
Molecular - - shows which atoms are involved with ratios
Structural - - shows how atoms are arranged in space
What are elements trying to achieve when they create bonds?
Noble gas configurations
