How many electrons are in a neutral atom? - KnowledgeBurrow
Web10 jul. 2024 · How many electrons are in Li? The atomic number of lithium (Li) is 3. Therefore its atoms contain 3 protons. A neutral atom has equal numbers of protons and electrons, so a neutral Li atom also has 3 electrons. What is lithium’s atomic number? WebAnswer (1 of 3): Lithium element number 3 in the periodic table of elements, meaning it has 3 protons in its nucleus. Therefore a Li-atom also has to have 3 electrons surrounding the nucleus. Li-ion has a charge of +1 so it has given up one electron. Therefore, the total number of electrons is 2. grafton ps improvement
