om's nucleus and, in a neutral atom, it also equals the number of electrons surrounding the nucleus. How do you determine the number of neutrons in an atom? Subtract the atomic number from the atomic mass (rounded to the nearest whole number): neutrons = atomic mass - ato
gativity quantifies an atom's ability to attract shared electrons; it varies across the periodic table. Polarity depends on both bond polarity and molecular geometry, influencing a molecule’s physical and chemical properties. Determining whether a molecule is
