Lithium number of neutrons and electrons
WebAs indicated on the periodic table, the atomic mass of Lithium is 7. Therefore, the number of proton in Lithium = 3 Atomic Mass of the Lithium = 7 The atomic mass of an element = Number of Proton + Number of Neutron Number of Neutron = Atomic mass of an element – Number of protons of the element Number of Neutron = 7 – 3 Web3 jul. 2024 · An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion. The number of neutrons doesn't come into play since they are electrically neutral. Changing the number of neutrons determines the isotope.
