Ionic Vs. Covalent
A metal and a non-metal element.
What elements make up an Ionic bond?
To be stable and fill their valence electron shells
Why do elements bond?
The rule that all elements follow for their valence electrons in their Lewis Structures except for Hydrogen
What is the octet rule?
BeH2
What is an example of a linear shape?
3D arrangements of molecules in space.
What is molecular geometry?
A non-metal and a non-metal element.

type of bond: NaCl (difference in EN of <1.7)
What is an ionic bond?
Number of electrons Hydrogen will get in Lewis Structures
What is 2 electrons?
H2O
What is an example of a bent shape?
Lone pairs and bonds are the central atom
What does the shape of the molecule depend on?
Hydrogen and a non-metal element.
What elements make up a polar covalent bond?
Shares electrons between elements.
What do covalent bonds do?
Number of electrons stored/shared in a double bond

BF3
What is an example of a trigonal planar shape?
The model that is used in chemistry to predict the geometry of individual molecules from the number of electron pairs around the central atoms
What is the VSEPR theory?
Elements are sharing electrons equally
What elements make up a non-polar covalent bond?
difference in EN between: 0.3 to 1.6
What is the electronegativity difference for polar covalent bonds?
Shows how valence electrons are arranged among atoms in a molecule.
