Valence Electrons
How do we determine valence electrons?
The group number determines the number of valence electrons.
The electrons are shared with covalent bonds.
What is a polar molecule?
Polar molecules are molecules that have both positive and negative ends.
What are the 3 intermolecular forces?
London dispersion, dipole-dipole, and hydrogen bonding
What is Mrs. Brown's favorite college?
A&M
How many valence electrons does Na have?
1
What is a covalent bond?
A bond between 2 non metals.
What is a nonpolar molecule?
Nonpolar molecules have the same charge all the way through.
What is a hydrogen bond?
Hydrogen bonds are between hydrogen and an electronegative element
Who is Sydni's favorite singer?
Harry Styles
How many valence electrons does Cl have?
7
What happens to electrons in ionic bonds?
The electrons are transferred.
When do we draw partial charges and the dipole arrow?
With polar compounds
How do melting/boiling points and intermolecular forces correlate?
The stronger the intermolecular force, the higher the melting/ boiling point is because it takes more heat to break the bonds.
Who is Mrs. Brown's favorite scientist?
Marie Curie
How many valence electrons does K have?
1
What is an ionic bond?
Ionic bonds are between a metal and a non metal.
To which element does a dipole arrow point to?
The most electronegative element
How do physical states and intermolecular forces correlate?
The force, if strong enough, will pull particles together, which can change the physical state.
What type of snake is Severus?
King snake
How many valence electrons does Te have?
6
What happens to the electrons in metallic bonds?
The electrons form an electron sea.
What is an example of a polar molecule?
H2O
