Answer 5

Families or groups

Question 6

Elements in the same family or group share common ______________.

Answer 6

Characteristics or properties. Also, they share the same number of valence electrons.

Question 8

The family of elements that is in group 18 (the last column on the right.) They do not react with other elements (inert) because they have all 8 of their valence electrons. He, Ne, Ar, Kr

Answer 8

Noble gases

Question 9

The family of elements that make up group 17. They are very reactive because they have 7 valence electrons and need one more to be stable.

Answer 9

Halogens

Question 9

The family of elements that are on the zigzag to the right of the periodic table. They have some properties of metals and some properties of non metals.

Answer 9

Metalloids

Question 10

The family of elements that make up most of the periodic table. Most of them are good conductors of heat and electricity. They have a shiny luster, are solid, ductile (can be stretched into wire), malleable (can be pounded into shape).

Answer 10

Metals

Question 12

The family of elements that are on the right side of the periodic table and lack the properties of metals. Many of these are gases at room temperature. Dull, brittle, poor conductors of heat and electricity.

Answer 12

Nonmetals
