When an atom bonds to another atom, it is trying to fill its
What happens during ionic bonding?
Electrons are transferred (gained/lost) between atoms, one because positive, other negative becomes attracted.
Ionic bonds are between METAL and NONMETAL
Compounds with 2 ions bonded are called anion
What is an ion?
Atom or group of atoms with a charge
How are ionic bonds held together?
In an ionic bond the cation
loses an electron making them positively charged.
In an ionic bond the anion
gains an electron making them negatively charged
The cation is the metal and is named
The anion is the nonmetal and is named
What is an oxidation number?
The charge on an atom, it gets its number by gaining or losing electrons.
When do you use Roman Numerals?
When the metal (cation) is in the p,d,f block
What is the octet rule?
Atoms gain,lose, share, electrons in order to have 8 electrons
What is a poly-atomic ion?
A group of nonmetals covalently bonded together that act in the outer shell
What happens during covalent bonding?
Electrons are shared.
Covalent bonds are between
Two non metals
What are the two types of covalent
Diatomic elements and polar covalent
List the 7 Diatomic elements.
Hydrogen (H2) Nitrogen (N2) Oxygen (O2) Fluorine (F2) Chlorine (Cl2) Iodine (I2) Bromine (Br2)
Explain polar covalent molecules
One atom in the molecule is more electronegative than the other atoms, pulls covalent bonds close, makes side of molecule more negative other side more positive
List the covalent bond types in order from weakest to strongest
Which group forms single covalent bonds when the molecule is diatomic?
Double covalent bonds?
Triple covalent bonds?
The overall charge of a compound should be
Mercury (I) Bromide
Di phosphorus pentoxide
Lead (II) Phosphate IONIC
Di Sulfur Trioxide COVALENT
Chlorine Tetra Flouride IONIC
TIN (IV) Bromide IONIC
Zinc (II) Nitrate
Lead (II) Nitrite
Tin (IV) Sulfide
Copper (II) Sulfate
Iron (III) Carbonate
