The Periodic Table

Question 1

What is electrical conductivity?

Answer 1

If an element is capable of conducting electricity.

Question 2

What are the oxides of metals?

Answer 2

metal oxides - they are basic

Question 3

What are the oxides of non-metals?

Answer 3

acidic or neutral

Question 4

What are metals?

Answer 4

elements that can conduct electricity and form basic oxides.

Question 5

What are oxides?

Answer 5

Compounds that form with one or more oxygen atoms. (eg. CO2)

Question 6

What are non-metals?

Answer 6

elements that don’t conduct electricity and form acidic/neutral oxides.

Question 7

Why do elements in the same group have similar chemical properties?

Answer 7

because they have the same number of valence electrons which determines and elements chemical behaviour.

Question 8

What are valence electrons?

Answer 8

loose/unpaired electrons on the outermost shell

Question 9

Why don’t the noble gases react?

Answer 9

they have a full outermost shell so they are stable and don’t need to bond (attractions/reactions)

Question 10

What group are the noble gases in?

Answer 10

group 0
