| Front | What are the steps to working out a molecule's shape?shortcut method |
| Back | 1) Group of central atom2) Number of atoms around central atom3) If it is an ion, how many electrons are lost or gained4) Number of total electrons5) Number of pairs of electrons6) Number of bonding pairs7) Number of lone pairs |
| Text | Covalently bonded atoms are held together by {{c1::the electrostatic force of attraction between the positively charged nucleus and the negatively charged pair of electrons}} |
| Back Extra |
| Front | What are the properties of a molecule with 3 bonding pairs and 2 lone pairs? |
| Back | 3 + 2 = 5 electron groups
 Shape name : T ShapedBond angle : ~90 degrees ~180 degrees |
