Chapter 8
Whats the difference between chemical formula and structural formula?
Chemical / water h20
Structural / h- 0 - h
The differences between molecular and ionic
Molecular- Low boiling point, gas/liquid room temp
ionic- High boiling point, High melting point
Some things to watch for when creating a double, triple or coordinate covalent bond are.
How many electrons, and correct number to make otect.
Determing factors of accurate model shape of a molecule is
Number of electrons, are there any unshared pairs
Single covalent bond- has two electrons and one bond.
Double covalent bond- Has four electrons and two bonds
Triple covalent bond- Has 6 electrons and three bodnds
Coordinate covalent bond- When one atom contributes both bonding electrons.
Polar bond- Electrons are shared unewually in a bond.
Diatomic molecule- a molecule consisting of two atoms
poly atomic ions- More than 2 elements together to form a molecule with a charge Example- NH4 is positive and PO4-3 is negative
polar bonds- unequal sharing determined by the subtraction of electro negative values
The cause of a bent shaped molecule is- unshared pairs of electrons or force- vsepr replleing force
9 Different shaped of ZSEPR are- Linear triatomic, trigonal planar, bent triatomic, pyramidal, tetrahedral, Trigonal bipyramidal, octahedral, squar planar, t-shaped.
