Atoms and Elements Mini-Quiz
Put your name date and class period at the top
right of a half-sheet of paper
 Number down the left, 1-10 skip a line between
each.
 If the statement is true, answer true.
 If the statement is false, correct the underlined
word to make it true.

Atoms are made up of protons, neutrons and
electrons.
Protons and neutrons have an electric charge.
Electrons and protons are found in the nucleus of
an atom.
If you change the number of neutrons in the
center of an atom, you change the type of
element.
The atomic number is equal to the number of
protons and electrons in an atom.
Quiz 6-10
If the statement is false, correct the underlined word to make it true

.
All elements, except Hydrogen, have two
electrons in the first energy level.
Chemical symbols can be one, two or three
letters.
The first letter of a chemical symbol is always
capitalized.
Elements at the bottom of the periodic table are
heavier than elements at the top.
The electrons in an atom are attracted to the
nucleus because of the neutrons.
Notes on the periodic table.
Get out your periodic table.
 Follow along as I show you how the periodic
table is organized on the overhead.
 I will post a pdf of the overhead notes on the
wiki this afternoon.
 For now, make sure you copy what I write so
that if you have questions you can come see
me.

Periodic table notes



By mid-1800’s 60
elements were known.
There was a lot of
information about these
elements, but it was not
organized.
1869- Russian scientist
Dmitri Mendeleev made a
chart of the know
elements.
We have added elements
to his chart as we
discovered more.
The current periodic table
Element arrangement
In the periodic table, the elements are
arranged in order of their atomic numbers
 Except for a few, atomic numbers are in the
same order as atomic masses.


The lightest element has the lowest atomic
number, the heaviest element has the
highest atomic number
• Hydrogen has an atomic number of 1, Aluminum
has an atomic number of 13. Aluminum is
heavier than Hydrogen.
Rows = “PERIOD”
Each row across the periodic table is
called a period.
 All the elements listed in a row belong
to the same period.


How many periods are in the modern
periodic table?
Column = “GROUP” or
“FAMILY”

Each column in the periodic table is
called a group, or family.
All of the elements in a group have
many similar properties.
 Each group is identified by a number.

• For example, the column of elements at the
left side of the table is Group 1.
Metals and Nonmetals
Elements can be divided into two types
 A heavy step-like line can be used to divide
the two.


Metals
• There are more metals
• Metals are on the left

Nonmetals
• Fewer non metals
• Nonmetals are on the right.

Day 4
DRQ: Use the periodic table to list a metal, a metalloid and a nonmetal
each with five outer-level electrons.
Activities:
 DRQ\Review DRQ
 Groups/Cooperative learning – Our own periodic table
 Using the atoms created on Tuesday and Wednesday, make a
periodic table in our room on the wall.
 In groups, complete any elements that are missing.
Closure: Checking Concepts Questions 1-10 page 294
Homework: Using your notes from 10-1 to 10-3 and the notes from
today, create a study guide about atoms, elements and the periodic
table. Complete the Reviewing Vocabulary on page 293
