Periodic Table, Trends, & Elements

Groups and periods

• Groups are the vertical columns on the periodic table.

• Periods are the horizontal rows.

• Elements in the same group will have the same characteristics because they have the same # of valence e-.

• Those elements in the same periods (rows) will have the same number of electron energy levels.

Multiple Choice

The properties of Carbon are expected to be similar to those of ...

• phosphorus

• silicon

• boron

• aluminum

Group Names

• Group 1 = Alkali Metals

• Group 2 = Alkaline Earth Metals

• Groups 3-12 = Transition Metals

• Group 17= Halogens

• Group 18= Noble Gases

Multiple Choice

What group is known as the Halogens?

• Group 2

• Group 18

• Group 17

Valence Electrons

These are the electrons on the outer most shell. Remember, the group number tells you how many valence electron an element has.

Multiple Choice

What group on the periodic table contains elements with a stable outer shell?

• 18

• 13

• 2

• 1

Other important information:

• Covalent bonds happen between NONMETALS only!

• Ionic bonds happen between a metal and nonmetal.

• Metals are on the left side of the periodic table, while nonmetals are on the right side.

Multiple Choice

• covalent

• Ionic

Multiple Choice
