And.. how is the behavior of isotope different? PLZ HELP! ASAP!

    An isotope is a version of an atom. So lets say you have an atom of carbon. You can also have an isotope of carbon, which will have a different amount of electrons. It is still carbon, but it has a different charge. So you may see it represented as C-2, or C-1. It still has the same amount of protons though so its still carbon.

    An isotope is an atom with a different number of neutrons, but the same number of electrons and protons. Usually, isotopes aren’t all too different, although their atomic mass is one amu less or more

    An atom is a single instance of some basic element, for example hydrogen. An isotope is also a single instance of some basic element, but with a different number of neutrons than the “normal” kind. For example, most hydrogen has a single proton in its nucleus. Deuterium (a hydrogen isotope) has one proton and one neutron in the nucleus. Tritium (another hydrogen isotope) has one proton and two neutrons in the nucleus.

    An atom is an isotope of a particular element. Isotopes are atoms of an element that have different numbers of neutrons in their nuclei. For example : the element hydrogen has 3 different isotopes – simple hydrogen has one proton in its nucleus that is orbited by one electron. The second isotope is called deuterium – it has one neutron and one proton in it’s nucleus orbited by one electron. The third isotope is tritium – it has two neutrons and one proton in its nucleus orbited by one electron. By the way hydrogen is the only element with different names assigned to it’s isotopes.
    The different isotopes all react chemically in the same manner. Some isotopes of an element may be radioactive and undergo radioactive decay forming other elements releasing energy. The isotopes will have different masses and therefore properties that depend upon mass (density) will be different
