Whats is an isotope?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons. The number of protons in a nucleus determines the element’s atomic number on the Periodic Table. For example, carbon has six protons and is atomic number 6.
What is an isotope Class 9?
Isotopes: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.
What are isotopes class 10th?
Isotopes are atoms of different masses of the same element. By having different numbers of neutrons in their nuclei they get these different masses. However, they are the same type of atom, because they have the same number of protons in their nuclei.
What is an isotope kid definition?
An isotope is one of two or more types of atoms of a chemical element with the same number of protons but with different numbers of neutrons and therefore different atomic masses. The isotopes of an element occupy the same position in the periodic table.
What are isotopes give Example Class 11?
In other words, isotopes are variants of elements that differ in their nucleon numbers due to a difference in the total number of neutrons in their respective nuclei. For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.
What is isotope and isobar with example?
Isotopes:- Same atomic number but different mass number. Example- C−12,C−14. Isobars:- Isobars are atoms of different elements having same mass number. These have equal number of nucleons but different number of protons, neutrons and electrons.
What is an isotope definition for dummies?
Atoms in a chemical element that have different numbers of neutrons than protons and electrons are called isotopes. The atoms in a particular element have an identical number of protons and electrons but can have varying numbers of neutrons.
What are the most common uses for isotopes?
List of Medical Isotopes Produced in Reactors and Their Uses: Iridium-192. Iridium-192 is used in prostate cancer and is a strong beta emitter. Lead-212. Lead-212 is used to treat breast cancer, melanoma, and also ovarian cancer through alpha radioimmunotherapy and targeted alpha therapy (TAT). Lutetium-177. Molybdenum-99. Palladium-103. Phosphorus-32. Potassium-42. Radium-223. Rhenium-186. Rhenium-188.
How do you identify isotopes?
Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. They both use the mass of the atom where mass = (number of protons) + (number of neutrons).
What are the different types of isotopes?
Scientists divide isotopes into two main types: radioactive and stable. Both types see wide use in several industries and fields of study. Stable isotopes help identify ancient rocks and minerals. Radioactive isotopes produce energy and serve in science, medicine and industry.
What are the different uses of isotopes?
Carbon dating makes use of Carbon-14,an isotope of Carbon.
