In a metallic solid, the forces of attraction are between the mobile valence electrons and the positively charged nuclei. So, the correct answer is D. Positively charged nuclei.

Here's why:

1. In a metallic solid, atoms are arranged in a closely packed repeating pattern.

2. Each atom in a metallic solid loses its valence electrons, which are the electrons in the outermost shell of an atom that are involved in chemical reactions.

3. These valence electrons are free to move throughout the entire structure, forming a 'sea' of electrons. This is often referred to as 'electron sea model'.

4. The positively charged nuclei (the central part of an atom that includes protons and neutrons) of the metal atoms are embedded in this 'sea' of delocalized electrons.

5. The forces of attraction between these free electrons and the positively charged nuclei hold the atoms together in a metallic solid. This type of bond is known as a metallic bond.

So, the forces of attraction in a metallic solid are not between the atoms (A), neutrons (B), or negative ions (C), but between the mobile valence electrons and the positively charged nuclei (D).
