What is an ionic bond? Name two substances that would bond ionically and what they would form.
|
When one atom gives away an electron to another atom.
Example: Sodium and Chlorine to form Sodium Chloride or Table Salt |
|
|
What is a covalent bond? Name two substances that would bond covalently and what they would form.
|
A covalent bond is when two atoms share electrons.
Example: Lithium (1 electron) + Florine (7 electrons) = Lithium Fluoride |
|
|
What is a chemical bond?
|
A chemical bond is a non contact force holding atoms together in a combined state
|
|
|
What is an isotope? Why are they important?
|
An element that has the same number of protons but a different number of neutrons in the nucleus. Important because the number of protons determines the Atomic Number
