- Chemical Bonding
- Ionic Bonding
- Electrons are transferred from one atom to another
- Non-metals + metals
- Ionic Compounds
- Made up of positive and negatively charged ions
- Have high melting and boiling points
- Electrically neutral
- sum of positive charged = sum of negative charges
- overall charge is 0
- sum of positive charged = sum of negative charges
- ionic bond attracts in all directions
- Covalent Bonding
- Electrons are shared between atoms
- occurs because the atoms in the compound both seek to gain electrons
- Occur in compounds consisting of non-metals
- an electron pair occupies the space between the two atoms
- negatively charged electrons are attracted to the positive charges if both nuclei
- directional attraction - only between the two atoms involved
- Dative Covalent Bond
- a shared pair of electrons in which both electrons come from the same atom
- Electrons are shared between atoms
- Dative Covalent Bond
- a shared pair of electrons in which both electrons come from the same atom
- Ionic Bonding
- Gained an electron = negative
- Non-metal ion = negative
- Oppositely charged ions are formed
- Ionic Bonding

- Made up of positive and negatively charged ions
- Have high melting and boiling points
- Electrically neutral
- sum of positive charged = sum of negative charges
- overall charge is 0
- sum of positive charged = sum of negative charges
- ionic bond attracts in all directions
- oppositely charged ions are attracted to each other by electrostatic forces
- creates ionic bond
- Ionic Bonding
- Non-metals of Groups 5-4 gain electrons- form negative ions
