What is an isotope and example?
Isotopes can be defined as the variants of chemical elements that possess the same number of protons and electrons, but a different number of neutrons. For example, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.
What is an isotope easy definition?
An isotope is one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
How are isotopes defined?
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
What are isotopes 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 11?
Isotopes are the atoms of an element which have the same number of protons but different numbers of neutrons. In other words, you can say that the isotopes have the same atomic number, as the number of protons remain the same, but they have different atomic masses due to the different number of neutrons.
What are isotopes Class 12?
Isotopes contain the same number of protons but with a varied number of neutrons. The pneumonic can be given as “isotopes contain the same number of Protons.” Therefore, carbon-12, carbon-13, carbon-14, carbon-15 are the isotopes.
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 are Isobar give example?
Isobars are atoms (nuclides) of different chemical elements that have the same number of nucleons. An example of a series of isobars would be 40S, 40Cl, 40Ar, 40K, and 40Ca. While the nuclei of these nuclides all contain 40 nucleons, they contain varying numbers of protons and neutrons.
What is Isobar Class 9 Example?
Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number but have the same mass number. An example of a series of isobars would be ⁴⁰S, ⁴⁰Cl, ⁴⁰Ar, ⁴⁰K, and ⁴⁰Ca.
What is Isobar and isotopes with example?
Isobar is an element that differs in the chemical property, but it has similar physical property. An example of two Isotopes and Isobars is nickel and iron. These both have the same mass number, which is 58, whereas the atomic number of nickel is 28, and the atomic number of iron is 26.
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.
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).
How do isotopes of an element differ from each other?
Difference Between Isotopes and Isomers Isotopes are different atoms of the same element. Isomers are different compounds with the same molecular formula. Isotopes differ from each other due to the number of neutrons, whereas isomers differ from each other due to the arrangement of atoms. Isotopes of a single element have the same chemical behavior, but the physical properties may differ.
What are stable and unstable isotopes?
A stable isotope is one that does not undergo spontaneous nuclear decay. An unstable isotope is one that does undergo spontaneous nuclear decay. Unstable isotopes are also referred to as radioactive isotopes, or radiosotopes, or radioactive nucleides, or radionucleides.
