A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. This quiz is incomplete! To play this quiz, please finish editing it.

39.0983 atomic mass units: Number of Protons: 19: Number of Neutrons: 20: Number of Electrons: 19: Melting Point: The symbol K comes from the Latin word kalium, Protons (the atomic number) and neutrons both contribute to the atomic mass. If you therefore subtract the number of protons (19) from the atomic mass (39), you are left with the number of neutrons (=20). How many neutrons do potassium 39 and potassium 40 have? Each isotope has 19 protons and 19 electrons, but the number of neutrons vary Symbol: K Atomic Number: 19 Atomic Mass: 39.0983 amu Melting Point: 63.65 °C (336.8 K, 146.57 °F) Boiling Point: 774.0 °C (1047.15 K, 1425.2 °F) Number of Protons/Electrons: 19 Number of Neutrons: 20 Classification: Alkali Metal Crystal Structure: Cubic Density @ 293 K: 0.862 g/cm 3 Color: silvery Atomic Structure How many neutrons are present in an atom of K that has mass number = 39? mass number = number of protons + number of neutrons number of neutrons = = = change Isotopes • Not all atoms of the same element contain the same number of _____ (remember number of protons determines the identity of elements, NOT the number of neutrons).
