Lecture 3 - Atoms Flashcards
Describe the VSEPR theory
Why atoms interact with one another
When is an atom unstable
When the outer shell is not filled to its capacity
3 ways to make an atom stable
- Give
- Take
- Share
3 types of bonds:
Ionic
Covalent
Hydrogen
Which type of bond:
When two atoms of the opposite charge interact
Ionic
Which type of bond:
The intermolecular force (not intramoleculur)
Hydrogen
Which type of bond:
When atoms share electrons in their outermost shell
Covalent
What is an atom that has gained or lost electrons
Ion
Which bond breaks in water
Ionic
Which bond is the weakest
Hydrogen
What does it mean when something is polar
Sharing unequally
What does it mean when something is nonpolar
Sharing equally
Most of your proteins and sugars are what type of bond
Covalent
Most of your proteins’ and sugars’ properties are what type of bond
Hydrogen
How to find the # of protons
Look at the atomic #
How to find the # of electrons
Look at the # of protons
How to find the # of neutrons
Take the atomic mass and subtract the # of protons
Why do atoms interact with each other
To fill up their outer shell to become stable
