Is the atomic mass on the top or bottom
Witryna22 mar 2024 · The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the table below, which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Witryna6 lis 2024 · In general, the largest atoms are at the bottom left side of the periodic table. Atomic Radius Versus Ionic Radius The atomic and ionic radius is the same for atoms of neutral elements, such as argon, krypton, and neon. However, many atoms of elements are more stable than atomic ions.
