Chapter 5 Flashcards
Why do elements bond
To lower their potential energy
What is an Ionic Bond
The electrostatic force of attraction between 2 oppositely charged ions
Do metals have a low IE or High IE
Low
Do non-metals have a low IE or High IE
High
What states are ionic bonds
Solids
What states are covalent bonds
Gassed and some are liquid and solid
How is the solubility of ionic bonds
Soluble in water
How is the solubility of covalent bond
Insoluble in water
How do U make an Ionic bonds
1 element donates all electrons
Make it an ion
Metals give all electrons to non metals
What is a covalent bond
Both elements share electrons
What happens when the electronegatively difference is less than 0.5 and more than 0.5
Less - considered npcb
More- considered pcb
What is the VSEPR Theory
Valence shell electron pair repulsion
What’s Non-Polar molecules
No pull
All npcb
What are Polar Molecules
Polar covalent bond
Has to have a pull
What 2 types of elements need to bond to form a
Ionic bond
Covalent bond
Metallic bond
Ionic bond - metal and non metal
Covalent bond - non metals
Metallic bond - metals
What is an intramolecular bond
And what are examples of them
Bonds that are used to make one molecule
- ionic
- covalent
What Is an intermolecular bond
Bond that is used to hold together many molecules
- hydrogen
- dipole
- Van Der Waals
What is a VDW Force bond?
Van Der Waals
Non polar molecule
What is a Dipole-Dipole force
Slightly + and - molecule being attracted to another end Polar Molecule (PM)
What is a Hydrogen Bond
Special type of dipole-dipole bond Polar Molecule (PM) Contains Hydrogen
