Answer:

The particle theory states that the particles of a substance spread out as they gain energy when heated. Thus, the particles take up more space, which means that the density of the substance decreases. It is almost always true that, for each pure sub stance (for example, gold), the density of its solid state is greater than the density

Learning Task 3: Answer the following

murzikaleks [220]

Explanation:

Picture A which shows an overall negative charge represents an anion. Anion are formed when an atom gains an electron. In doing that, the total number of electrons (negative charge) is greater than the number of protons (positive charge), hence it would have an overall negative charge.

Picture B which shows a neutral charge represents a neutral atom. In an atom, the number of electrons equals the number of protons.

Picture C which shows an overall positive charge represents a cation. Cation are formed when an atom loses an electron. In doing that, the total number of electrons (negative charge) is less than the number of protons (positive charge), hence it would have an overall positive charge.
