Verified step by step guidance1
Recall that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of lithium, which represents the number of protons in the nucleus of a lithium atom.
Look up the atomic number of lithium on the periodic table; lithium has an atomic number of 3.
Since the atom is neutral, the number of electrons equals the number of protons, so lithium has 3 electrons.
Therefore, the total number of electrons in a neutral lithium atom is 3.
