Here are the answers for A and B.
Answer:
(a) 80% are metals.
(b) (1.) Metals are malleable and ductile. (2.) Metals are dense.
Step-by-step explanation:
(a) If you look at the picture, there are faint lines dividing the circle into ten parts. Metals take up 8 sections and non-metals take up 2. This means that the number of metals on the periodic table takes up 80% and non-metals take up 20%.
(b) There are many physical properties of metals, but two of them are that metals are malleable & ductile (these relate to how metal can be shaped) and that metals are dense (density = mass ÷ volume).
