VSEPR
What does VESPR stand for.
Valence Shell Electron Pair Repulsion
What determines the valence electrons.
The groups on the periodic table.
What do intramolecular forces do?
Hold the molecule together
What is a metallic bond?
2 metal ions formed by a shared bond
What is VSEPR used to predict?
All ionic compounds are....
Polar.
What are 3 types of bonds?
Covalent, ionic, metalli.
The forces between the molecules are?
Intermolecular forces
The strength of a metallic bond is determined by?
Number of electrons, size of the metal, charge of the metal
What is the difference between electron and molecular geometry?
Electron geometry is the shape of all electron around the central atom shared or unshared while molecular geometry is the shape of just atoms or shared pairs around the central atom
What does VESPR help us determine
The shape of the molecule.
Metallic ions are connected between....
A sea of electrons
What state has the strongest intermolecular force?
Solids
Electrons move around freely in a?
Sea of electrons
What does the shape of a molecule determine?
the function
What is polarity?
Its the physical property that can determine other properties for the compound.
What is the octet rule.
Where elements will combine or bond. So they have a complete outer energy level. (8 electrons in the outer energy level)
What are the three intermolecular forces?
London dispersion, dipole-dipole, and hydrogen bonding
What are properties of metallic bonds?
Good conductor, high melting point and boiling point, high density, malleable, and ductile
What is it called when elements combine so atoms can have a complete outer energy shell
The Octet Rule
What is the electron geometry of CF4?
Tetrahedral.
What other bonds do covalent bonds also have?
Double and Triple covalent bonds.
(Double bonds = 2 atoms shared 4 electrons)
(Triple bonds = 2 atoms share 6 electrons)
What three elements can hydrogen bond with in a hydrogen bond?
Fluorine, oxygen, and nitrogen
Examples of metallic bonds
Gold bars, aluminum foil, and copper wire
A metal and nonmetal where one atom donates an electron and the other accepts one
Ionic bond
