Question 3

What are periods?

Answer 3

Rows of the period table.

Question 4

What are groups?

Answer 4

Columns of the periodic table.

Question 5

What are characteristics of alkali metals?

Answer 5

Found in period 1 of the periodic table (except hydrogen).
Have one electron in their outermost layer of electrons.
Easily ionized.
Silvery, soft, and not dense.
Low melting points.
Incredibly reactive.

Question 6

What are characteristics of alkaline earth metals?

Answer 6

An oxidation number of +2 which makes them very reactive
Not found freely in nature
Two electrons in their outer shell
High melting points
Low density

Question 7

What are characteristics of halogens?

Answer 7

Halogens are nonmetals in group 17 of the periodic table.
Down the group, atom size increases.
The more down the group the higher the boiling points
Halogens have high effective nuclear charge
Halogens can be harmful or lethal to biological organisms in sufficient quantities.

Question 8

What are characteristics of noble gases?

Answer 8

Noble gases are found in the 18th group
Noble gases are colourless.
Odorless.
Tasteless.
Nonflammable gases under standard conditions.
In the periodic table, the noble gases are arranged according to their boiling point.
Noble gases are widely used in different fields, from incandescent lighting to excimer lasers
