Ionic Vs. Covalent
A metal and a non-metal element.
What elements make up an Ionic bond?
To gain potentially energy and stability.
Why do elements bond?
Octect Rule.
What is the rule that all elements follow for Lewis Structures except for hydrogen and boron?
BeH2
What is an example of a linear shape?
3D arrangements of molecules in space.
What is the definition of molecular geometry?
A non-metal and a non-metal element.
What elements make up a polar covalent bond?
1.7 and above
What is the electronegativity difference for an ionic bond?
2 electrons
How many electrons will Hydrogen get in Lewis Structures?
H2O
What is an example of a bent shape?
Bond types and molecular geometry.
What do the properties of molecules 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?
6 electrons
How many electrons will Boron need in Lewis Structures?
BF3
What is an example of a trigonal planar shape?
VSEPR Theory.
What is the model that is used in chemistry to predict the geometry of individual molecules from the number of electron pairs around the central atoms?
Elements are diatomic.
0.3 to 1.6
Shows how valence electrons are arranged among atoms in a molecule.
What is the purpose of Lewis Structures?
NH3
What is an example of a trigonal pyramidal shape?
2:1 and 2:2
What is the ratio of bonded to non-bonded pairs in a bent molecular geometric shape?
A metal gives electrons to a non-metal. The metal loses electrons and the non-metals gains electrons.
What is the process of an Ionic bond?
0.0 to 0.2
What is the electronegativity difference for non-polar covalent bonds?
2 shared electrons
What is the line in between elements in Lewis Structures?
SO4
What is an example of a tetrahedral shape?
4:0
What is the bonded and non bonded ratio of a tetrahedral shape?
