|
What is an orbital? |
A region of space, within an energy level in which an electron with given energy is found. |
|
|
What is an ionic bond? |
A metal (anion) and a non metal (cation) when the metal steals electrons. |
|
|
What is a covalent bond? |
Two non metals sharing electrons. |
|
|
What makes a polar molecule polar? |
The negative charge of electrons is not evenly distributed among the atoms. |
|
|
What are intramolecular forces? |
The relatively strong bonds or forces of attraction and repulsion within a molecule. |
|
|
What are intermolecular forces? |
The relatively weak forces within different molecules. |
|
|
What are dipole-dipole forces? |
A force that occurs between different polar molecules. It is the attraction between - and + sides. The force is an intermolecular force. |
|
|
What are London forces? |
Weakest van der walls force that occurs in all molecules. Is is an intermolecular force. |
|
|
If two molecules have the same forces but one has 36 electrons and one has 54, which will have a higher boiling point? |
The one with 54 (the higher ammount) of electrons. |
|
|
If two different molecules both have 70 electrons, what could explain one molecule having a higher boiling point than the other? |
The molecule with the higher boiling point has more intermolecular forces. |
|
|
What is hydrogen bonding? |
Simultanius attraction of a hydrogen nucleus (proton) that is covalently bonded to a very electronegative atom. |
|
|
What molecules are involved in hydrogen binding? |
H-F H-O H-N |
|
