SCIENCE (PERIODIC TABLE)

Question 1

Properties of metals

Answer 1

-malleable
-ductile
-good conductors of heat and electricity
-can be polished to produce a high shine
-solid at room temperature

Question 2

Properties of non-metals

Answer 2

-brittle
-cannot be bent into shape
-usually melts at lower temperatures
-poor conductors of electricity
-cannot be polished to give a shine like metals

Question 3

What elements in the same group have in common with each other

Answer 3

They have similar properties because they have the same number of valence electrons

Question 4

How to identify the location (group and period) of an element

Answer 4

Group: valence electrons
Period: number of shells
