|
Why do atoms want to form chemical bonds? |
To reach a lower energy state, making them more stable, by having a full outer shell/ring. |
|
|
What is a valence electron? |
the electrons that are located in the outer electron ring and involved in bonding |
|
|
What is the octet rule? |
atoms tend to gain, lose or share electrons to get a full outer shell with 8 valence electrons |
|
|
How many electrons fit on the first ring of an atom? |
two (2) |
|
|
What is an Ionic Bond? |
The bond that involves positive and negative ions where electrons are transferred. |
|
|
What elements are involved in an Ionic Bond? |
Metals & Nonmetals |
|
|
What elements are involved in a Covalent Bond? |
Only nonmetals |
|
|
What elements are involved in a Metallic Bond? |
Only metals |
|
|
What is a Metallic Bond? |
A bond between metals where they change into positive ions after donating valence electrons to the group, creating a "sea of electrons". |
|
|
What is a Covalent Bond? |
A bond where electrons are shared between non-metals |
|
|
What is a Lewis Dot Structure? |
A way of representing the valence electrons available for bonding around the symbol for an atom or molecule. |
|
|
In an Ionic bond, what type of elements gain electrons? |
Nonmetals |
|
|
In an Ionic bond, which type of elements lose electrons? |
Metals |
|
|
