Metals & Non-Metals

Question 1

what type of ions do metals form

Answer 1

positive ions (cations)

Question 2

what type of ions do non-metals form?

Answer 2

negative ions (anions)

Question 3

three general properties of metals:

Answer 3

Good conductors of heat

Sonorous (produce a ringing sound when struck)

Malleable

Question 4

Metals are very strong, as the ions are held together by metallic bonds.

They also tend to be malleable, which means they can bend without breaking.

Non-metals, in contrast, break easily, and so are said to be ______

Answer 4

brittle

Question 5

Many transition metals can be used as catalysts. What is the definition of a catalyst?

Answer 5

A substance that can speed up a chemical reaction without being used up

Question 6

transition metals

Answer 6

Transition metals share the same properties as metals, however, they have their own section of the periodic table between groups 2 and 3. These metals can form more than one type of ion that form different coloured solutions.

Question 7

why are metals towards the bottom of the table more reactive?

Answer 7

elements far down the table have lots of shells so the outermost shell is really far from the nucleus so the nucleus can’t hold on to those electrons in place so strongly so the atom will lose them more easily and form a positive ion. they are more likely to lose their electrons during a reaction
