|
What is a bohr Diagram?
|
The arrangement of subatomic particles in atoms and ions.
|
|
What is a full Bohr Diagram called?
|
A stable octet. The first shell can hold only 2 electrons, the second can hold a maximumu of 8.
|
|
The outside shell of a Bohr Diagram is called...?
|
A valence shell.
Electrons within this shell are hence called valence electrons. |
|
What is an Ionic Compound?
|
A compound which contains a positive ion and a negative ion
(usually a positive metal and a negative non-metal). |
|
What is Ionic Bonding?
|
When the metal atoms lose eletrons:
forming cations; (i.e. Aluminum forms a 3+ cation as a result of losing three electrons). |
|
What is an Anion?
|
When a non-metal atom gains electrons.
(Tip: Common ions are shown in the corner of the element's box. For multivalent metals: The most common charge is shown first). |
|
What is a covalent compound?
|
When the atoms of a non-metal share electrons with other non-metal atoms.
|
|
What is a covalent bond?
|
When a covalent compound is formed; the remaining unpaired electron will pair together and form a covalent bond.
|
|
