2b
8th – Lesson 1.2
Name: ____________________________________
Period: ____
Predict the properties and interactions of given elements using the periodic
table of the elements. (DOK 2)
SWBAT explain the periodic table and its values as well as the significance of
the number of protons in an atom.
Unit 4 – Chemistry: Periodic Table
Daily Question: What is everything around us made up of?
Key Points on the Periodic Table:
1. The number of protons is an atom determines the identity of the atom.
a. All atoms with 1 proton will be hydrogen atoms.
b. All atoms with 6 protons will be carbon atoms.
c. The number of protons in an atom changes very rarely and only with certain
substances.
2. Each different type of atom is shown on the periodic table.
a. There are 118 different types of atoms, each shown on the periodic table.
b. It was created in 1869 by a Russian scientist named Dmitri Mendeleev.
3. A substance that is only made up of one type of atom = element
a. There are 118 different elements.

one atom of this element.
Element Name: Each
element has a unique
name
Atomic Mass: This shows us
what the mass of the
atom is (how heavy it is). It
is measured in atomic
mass units.
4. The atomic mass is equal to the number of protons and neutrons that make up the atom.
a. To determine the number of neutrons in an atom, subtract the atomic number from the
atomic mass.
