WebSep 6, 2024 · An isotope is an atom that has a few extra (or missing) neutrons, and therefore a different atomic mass. Isotopes are usually written like this: Z A X Here, X is the element symbol, Z is the atomic number, and A is the atomic mass. The number of neutrons in the isotope is just # neutrons = A − Z Example: Complete the following table: WebThe fundamental cause of these patterns is atoms' electron configurations. Atoms with an equal number of positively charged protons and negatively charged electrons are only included in the periodic table together with isotopes, which are atoms with the same number of protons but differing quantities of neutrons.
