Isotopes are the atoms of the same element with same atomic number but different massnumber. Isotopes of same element have same chemical properties due to same number of electrons. Atomic number of an atom is the number of electrons / protons in it and mass number is the sum of protons and neutrons 17 (i) Hydrogen has 3 isotopes H, D and T. Number of electrons and neutrons in T will be |
|
Answer» Isotopes of any given ELEMENT all CONTAIN the same number of protons, so they have the same ATOMIC number (for EXAMPLE, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers. |

Isotopes are the atoms of the same element with same atomic number but different massnumber. Isotopes of same element have same chemical properties due to same number ofelectrons. Atomic number of an atom is the number of electrons / protons in it and massnumber is the sum of protons and neutrons |
|
Answer» Answer: All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. For example, all carbon atoms have six protons, and most have six neutrons as WELL. But some carbon atoms have seven or eight neutrons INSTEAD of the usual six. Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical PROPERTIES. That's because they have the same numbers of protons and electrons. An Example: Hydrogen Isotopes Hydrogen is an example of an element that has isotopes. Three isotopes of hydrogen are modeled in Figure 5.8.1 . Most hydrogen atoms have just one proton and one electron and lack a neutron. These atoms are just called hydrogen. Some hydrogen atoms have one neutron as well. These atoms are the isotope named DEUTERIUM. Other hydrogen atoms have two neutrons. These atoms are the isotope named tritium. The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3). Figure 5.8.1 : The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3). (CC SA-BY 3.0; |
