The Periodic Table has metals, nonmetals, and metalloids

Metals are on the left side of the stair-step (The stair step is the zig zag pattern of elements between the metals and nonmetals. The elements in the step are metalloids) There's only 1 nonmetal on the metal side and that is Hydrogen which is the the first block. Metals are shiny, and have malleability, ductility, and are good conductors.

metals are on the left side of the stair-step
Iron is a metal and is Fe on the Periodic Table

Next is Nonmetals are on the right side of the stair-step There's only 1 nonmetal on the metal that is on the metal side and that is Hydrogen. Nonmetals are elements that lack the physical and chemical properties of metals and are generally poor conductors of heat and electricity.

These are can of Nitrogen, which is a nonmetal and a gas, Nitrogen is N on the Periodic Table
The picture above is the atoms structure

Atoms are made up of Protons, Electrons, and Neutrons. The protons and neutrons are in the nucleus of the atom, and the electrons are in the electron cloud of the atom.

Protons have a positive charge, and are equal to the number of electrons in that atom

Electrons have a negative charge, and are equal to the number of protons in that atom

Neutrons have a neutral charge, they're not positive nor negative

The Reactivity of the elements on the periodic table decreases as you go right. And as you go down the Groups the reactivity increases.

Group 1 is the most reactive group and Group 18 is the least reactive group.

The Periodic Table is separated into Columns (Groups or Family) and Rows (Periods). Columns are the vertical ones, and Rows are the horizontal ones. Columns have the same number of valence electrons, and Rows have the same number of energy shells/rings.

There are 18 Columns (Groups) , and there are 7 Rows on the Periodic Table.

The Groups of the Periodic Table:

Group 1: The Alkali Metals

Group 2: The Alkaline Metals

Group 3-12: The Transition Metals

Group 13: The Boron Family

Group 14: The Carbon Family

Group 15: The Nitrogen Family

Group 16: The Oxygen Family

Group 17: The Halogens

Group 18: The Noble Gases

On the Periodic Table each element has an Atomic Number, Atomic Mass, and a Mass Number.

The Atomic Number tells use of many Protons and Electrons that are in that element.

The Atomic Mass tells use the number of Protons and Neutrons that are in that element

The Mass Number is the Atomic Mass rounded

Atomic number = # of Protons and Electrons

Atomic mass = # of Protons + Neutrons

You know the number of electrons in that element because the number of electrons equals the number of protons

The model above shows & labels an atom. You can see the Electron Cloud and the Nucleus. The picture above has 4 Valence Electrons, they (Valence Electrons) are the electrons in the outer energy shell/ring

The picture above shows the pattern for drawing an atom

When you are trying to Balance Chemical Equations you have to make sure both sides of the equation is equal.

You should list the elements in the same order on both sides of the equation.

The reactants are on the left side of the arrow and the products are on the right side of the arrow in the equation. Reactants are the stuff that's going into the chemical reaction, and the Product(s) are the results of the chemical reaction.

The background is an example of the stuff I just explained and how to balance a chemical equation

The 5 signs of a chemical change:

The substance is Bubbling

Change in Color

Change in Odor

Gas is formed

Precipitate is formed
