atoms of the same element w/different #s of neutrons are called isotopes. in order to know how many neutrons in an atom you must be told. the mass number tells you how much mass t 13、he atom has. since p+ and n0 are the heavy parts, mass # = # of p+s + n0s.question: if...
Isotopes - isotope: atoms of the same element that have different numbers of neutrons - Carbon, as found in nature, is a mixture of isotopes, including atoms of carbon-12, carbon-13, and small amounts of carbon-14. Isotopes atomic weight - The atomic weight of an element is the weighted...
Atoms of the same element may have different numbers of neutrons. Atoms with extra or missing neutrons are called isotopes. An atom’s mass number is the number of protons plus neutrons. Different isotopes of an element have different mass numbers. Atomic number of this neutral atom = 6. ...
Isotopes are atoms of the same element with different numbers of neutrons. The isotopes of hydrogen are represented as: 1 2 3 H H H . 1 1 1 Isobars are atoms with the same mass number but different atomic numbers. As a result, isobars are different elements. Isotopes are more commonly...
