What type of ions do nonmetals naturally form?

Negative Ions

Explanation:

Nonmetals naturally form Negative Ions by gaining electrons to fill the valence shell

False (1). Reference to, or calculation of, different densities leading to

different masses (1) (2 marks)

b True (1). Density of olive oil is less than water and sea water but greater

than that of alcohol (1) (2 marks)

c False (1). Gold has a greater density than aluminium so equal masses

for both mean that gold will have a volume that is much less than that

of aluminium (about 7

1 of that of aluminium) (1) (2 marks)

d True (1). Use of mass = density × volume for both leads to the same mass;

or a similar argument (1)
