Valence electrons &
Lewis Dot Diagrams
Valence electrons: are electrons that are
the furthest from the nucleus and are
also transferred or shared during
There is a pattern across the periodic
table that the valence electrons follow:

Writing Chemical Formulas
For Ionic Compounds
(metal + Non metal)
Chemical formulas: are made of the
chemical symbols of the elements that the
compound is made of.
The overall charge of ionic (metal + non
metal) compounds are neutral.
Each element has an
The Periodic Table
And its Trends.
Ionization energy: the amount of energy
required to transfer the valence (furthest
from the nucleus) electrons to another atom.
Electro negativity: is an elements ability
to attract electrons once the element has
Phase of matter
The students will learn what the phases of
matter are, the changes they go through,
how energy is involved and how to collect
and graph data while matter is going
through a phase change.
There are 4 phases of matter: solid
Polyatomic ions and
The transition metals are the block of
metals in the middle of the P. table that
dont belong to any of the families.
These metals can often have several
oxidation numbers, which gives them
Ion exchanging (Predicting Products).
Predicting Products: of a chemical
equation can be done if you are given the
formulas of the products.
You can do this by following these steps:
1.) First assign the oxidation to all of
the elements that are products.
The observations of a flame test and
acid test that are ran on the reactants and
the products of a double replacement
reaction can be used to determine the
identity of the products.
M. Defect: Is a theory that the mass of any
nucleus of an atom is less than the sum of the
Protons + Neutrons.
The mass of a Proton (1.00728 AMU) is not
equal to the mass of a Neutron(1.00866
Therefore the mass of one carbon atom (6
Acids are classified into two main
categories: Binary and Ternary.
Binary acids: are acids that are made of
two elements. Since all acids have
hydrogen in them, binary acids have
hydrogen and some non metal in them.
You can name acids by doin
Acids, Bases and
Acids: are solutions that are corrosive, sticky
to the touch and usually taste sour.
Bases are solutions that are also corrosive,
slippery to the touch and usually taste bitter.
Example: any kind of soap
