A look at the Lithium atom Atomic Number 11 3 Li Na Atomic Symbol Lithium Atom Sodium Name Lithium 22.99 (23) Atomic Mass 6.941 (7) Atomic Number = Number of Protons = 3 Atomic Mass - Atomic Number = Number of Neutrons 7 - 3 = 4 Number of Protons = Number of Electrons = 3 11
Slide 12: A look at the Lithium Ion
A look at the Lithium Ion Ions With ions it’s all about the Atoms with “missing” or “extra” electrons. An ion can have electrons. positive charge when it Li is missing electrons, or it Lithium atom can have negative 3 protons charge when it acquired 4 neutrons 3 electrons extra electrons! Li+ Lithiu
