Verified step by step guidance1
Recall that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of lithium (Li) from the periodic table, which represents the number of protons in the nucleus.
Note that the atomic number of lithium is 3, meaning it has 3 protons.
Since the atom is neutral, the number of electrons must also be 3 to balance the positive charge of the protons.
Therefore, a neutral lithium atom contains 3 electrons.
