1.
[2]
2.
(c) Plastic and stainless steel are synthetic materials. What is meant by
synthetic?
[1]

Two properties of heating metal

1.high melting points.

2.malleable

What is meant by synthetic?

1.made of artificial material, not natural items, synthetic is made up of chemical synthesis. (synthetic compound, synthetic drug, synthetic material)

Explanation:

1.They are solid (with the exception of mercury, Hg, a liquid).

2 They are malleable (they can be easily hammered into very thin sheets).

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
