Chem Chapter 12 Review

Bonding electron is the election that is bonded to the central atom while a lone pair are the small ones bonded together at the top of the central atom

Ionic bonds are where the atoms steal electrons from one another

Covalent bonds are where they are shared

Polar covalent bonds are where the electrons are unequally shared in between the atoms

To predict formulas of compounds based on charges, look at the family charge, and then use the criss cross method

STUDY THE TABLE

As the family’s move down, electronegativity decreases

As the periods move right electronegativity increases

The further the elements on the periodic table, the more the E.N is going to be

To predict VSEPR geometry: Find the lewis structure and then use the graph to find the geometry

The more positive the charge, the higher the ionization energy

Moving across a period on the periodic table, the effective nuclear charge increases, leading to smaller atoms and ions

However, for ions with the isoelectronic, the one with the greater positive charge will be smaller.

If a molecule exhibits resonance then it has many different ways to draw its lewis configuration
