Answer:

Since the most common isotope of #Li# is #""^7Li#, 92.5% abundant, there would likely be 4 neutrons in the single nculeus.

The atomic number (#Z#) of Li is 3 (i.e. so all Li nuclei contains 3 protons). There are several common isotopes with #""^7Li# the most common at 92.5% abundance. The average atomic mass of Li is 6.941 g, so it makes sense that this isotope is widespread.
