The property that is NOT true for halogens (group 7 elements) is "Conduct electricity". Halogens are poor conductors of electricity. Here's why:

1. Halogens are non-metals: Non-metals are generally poor conductors of heat and electricity. This is because they lack free electrons that can move and carry an electric charge.

2. State at room temperature: Halogens can be found in all three states of matter at room temperature (solid, liquid, and gas). However, none of these states conduct electricity well.

3. Electron configuration: Halogens have seven electrons in their outermost shell. They tend to gain an electron to achieve a stable electron configuration, rather than lose or share electrons to conduct electricity.

So, while halogens do have low density, low melting points, and their reactivity decreases down the group, they do not conduct electricity well.
