Web29 aug. 2024 · A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion. Advertisement How many valence electrons does Li+ have? Lithium possess one valence electron. The atomic number of … WebLithium has an atomic number of 3. So for an atom to be known as a lithium atom, it must have 3 protons. For example, if an atom has 4 protons, it will no longer be lithium, but will instead be beryllium. Any atom that doesn’t have 3 protons is not lithium .
