- Metals plus a non metal makes solids
- All metals expect mercury form solids
- Non metals plus a non metal makes solid, liquid and gases
- Noble gases cannot be found in nature
- Ionic compounds is metals plus a non metal
- Molecular compounds is a non metal plus a non metal
- Bohr models show all the valence shells
- Valence shells is the shells
- Octet is the outer valence shell
- Octet rule is when atoms want to gain or lose electrons to gain a full valence shell
- Groups are vertical
- Periods are horizontal
- Atomic number is how much electrons
- Groups show the valence electrons
- Electron dot diagrams are also called lewis dot diagrams
- Lewis dot diagrams only show the number of valence electrons
- Ionic bonding occurs between metals and non metals
- Group 18 is not reactive
- Group one is very reactive
- Lone pairs are two electrons
- Ionic bonds is when metals lose their electrons to complete the valence shells of a non metal
- Metallic bonds occur within metals
- Transition metals lose different numbers of electrons to form ions
- Formation reactions with square brackets only happen with ionic bonds
- Covalent bonding is also called molecular bonds
- Molecular bonds share electrons to complete valence shells
- Molecular bonding has two non metals
- Molecules are non metals
- Boron has three valence electrons and will complete at 6
- Berylium has two valence electrons and will fill with 4
- When drawing out molecular bonds make sure all of them have octets
- Metal loses electrons, non metal gains electrons
- The negative ion is called anion
- Resonance structures is data that shows there is more than one lewis dot diagram
- When drawing out molecular bonds if it has a charge add or subtract the electrons and add the charge and square brackets when drawing out
- Coordinate covalent bonds is when an atom gives both electrons to form a bond
- Metalic bonds have a delocated electrons which allows metals to be good conductors
- Electronegativity is the relative measure of an atoms ability to attract the shared electrons in a chemical bond
- As electronegativity increases the size of the atom decreases
- Non polar covalent has a charge of 0
