Quick Answer: What Does Isotope Mean In Science?

What is a isotope in science?

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 3 examples of isotopes?

The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.

What is isotopes explain with 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, uranium-235 and uranium-239 are two different isotopes of the element uranium.

How do you explain 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, we can also say that isotopes are elements with the same atomic number but different mass numbers.

What is an isotope easy definition?

Isotope, 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 behaviour but with different atomic masses and physical properties.

Are isotopes important?

Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation, archaeological dating of artifacts and medical diagnosis and treatment.

What are 2 examples of isotopes?

Examples of Isotopes:

  • Carbon-14. A naturally occurring radioactive isotope of carbon having six protons and eight neutrons in the nucleus.
  • Iodine-131. It is an isotope because it contains a different number of neutrons from the element iodine.
  • Tritium.

What are the 2 types of isotopes?

Isotope Facts All elements have isotopes. There are two main types of isotopes: stable and unstable (radioactive). There are 254 known stable isotopes. All artificial (lab-made) isotopes are unstable and therefore radioactive; scientists call them radioisotopes.

What are 3 uses of radioactive isotopes?

The most widely used radioactive pharmaceutical for diagnostic studies in nuclear medicine. Different chemical forms are used for brain, bone, liver, spleen and kidney imaging and also for blood flow studies. Used to locate leaks in industrial pipe lines…and in oil well studies.

Why do isotopes occur?

Isotopes can either form spontaneously (naturally) through radioactive decay of a nucleus (i.e., emission of energy in the form of alpha particles, beta particles, neutrons, and photons) or artificially by bombarding a stable nucleus with charged particles via accelerators or neutrons in a nuclear reactors.

What are the applications of isotopes Class 9?

Uses of Isotopes: Even fossil’s age can be determined by using this technology. An isotope of uranium is used as fuel in nuclear reactor. An isotope of cobalt is used in treatment of cancer. An isotope of iodine is used in treatment of goitre.

How are isotopes used in everyday life?

Research laboratories, medical centers, industrial facilities, food irradiation plants and many consumer products all use or contain radioisotopes. The most commonly known use of radioactive materials is nuclear power generation. Nuclear reactors are also used to power submarines, aircraft carriers and spacecraft.

How are isotopes written?

Isotopes are written in two different ways. They can be written using their symbol with the mass number (to the upper left) and atomic number (to the lower left) or the isotope name is written with a dash and the mass number. For example: Two naturally occurring isotopes of chlorine are chlorine-35 & chlorine-37.
