Atomic Number - correct answer-The number of protons in the nucleus of an atom. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same. Hydrogen = 1, Carbon = 6, Oxygen = 8 (located on top of element of periodic table) Mass Number - correct answer-# of neurons + # of protons = mass number (located on bottom of periodic table) Isotopes - correct answer-Let's say an atom is missing a neutron or has an ...
