Periodic Table
Unit 2 lesson 1

SWBAT:describe how the modern periodic table is organized by atomic number and grouped by element properties.

Groups are Vertical and they tell you the Valence Electrons of the element.

Periods are Horizontal and they tell you the orbital they contain. .

Multiple Choice

Which Group/Familly is the most stable and why?

Alkaline metals (Group 1) because they only have 1 VE which means they don't have enough energy

Halogens (Group 17)

Because number 7 means stability and fullness

Noble gases (Group 18)

Because elements have a full valence electron shell.

Multiple Choice

Lithium (Li) is found in which group and Period?

Group 2, Period 1

Group 1, Period 3

Group 2, Period 2

Group 1, Period 2
