Periodic Table

Metals- Metal elements

Nonmetals- nonmetal elements

Metalloids- Both metal and nonmetal

Protons, Neutrons, and Electrons

Protons- Positive charge

Neutrons- No charge

Electrons- Negative charge

Father of the Periodic Table was Dmitri Mendeleev

Reactivity- The reactivity of the elements depends on the number of electrons in the outermost shell

Phosphorous is the least reactive one.

Fluorine is the most reactive non metal

18 Groups on the periodic table

The Alkali Metals group 1,

The Alkaline earth Metals Groups 2,

Transition metals group 3-12

Boron family group 13

Carbon family group 14

Nitrogen family group 15

Oxygen family group 16

Halogens group 17

Noble gases group 18

Atomic number, Atomic Mass and Mass Number

Atomic Number = Number of protons

Atomic Mass = Number of protons and neutron

I know the number of electrons because it is the same as the number of protons


Electron Cloud

Valence Electrons are associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

2,8,8,8,8….. Means only two atoms can go into the first ring then 8 in the rest of them

Balancing Electrons

Protons are on the left of the arrow products are on the right

Chemical & Physical Properties

A physical property is a characteristic of a substance that can be observed without changing it into another substance.

A chemical property is a characteristic of a substance that describes its ability to change into a different substance.

Color change

Gas (bubbles)

Unexpected Temperature change

Formation of a precipitation

A solid produced when two liquids chemical combined
