Lithium atom atomic number
WebThree numbers surround the element symbol: the mass number ( A), electrical charge (no number is displayed if the atom is neutral), and the atomic number ( Z). Investigate : Watch how the numbers change as you add or remove parti cles. A. ... How many electrons are in a neutral atom of lithium? 0. B. How many neutrons are in an atom of Mg-25? C. WebThis number is the atomic number of the element and we give it the symbol Z. For example, lithium atoms contain 3 protons. The atomic number of lithium is 3. Any atom that has 3 protons must be a lithium atom. Putting it in symbols: We can show this information about an atom using its symbol and atomic number:
