For example,
Carbon-12, Carbon-13, and Carbon-14
are the three isotopes of the element Carbon with mass numbers 12, 13 and 14 respectively. The atomic number of Carbon is 6, which means that every Carbon atom has 6 Protons so that the Neutron numbers of these isotopes are 6, 7 and 8 respectively.
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 are isotopes give 2 examples?
The examples of radioactive isotopes are
uranium- 235 and uranium- 238
. Some other examples of isotopes are carbon -12, Carbon -13 and carbon -14. In this example the numbers 12,13 and 14 represent the number of neutrons.
What is isotopes and its examples?
Isotope → Isotopes are atoms with the same number of protons, but differ in numbers of neutrons. Isotopes are different forms of a single element. Example –
Carbon 12 and Carbon 14
are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons.
What are isotopes give Example Class 9?
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 atomicity Class 9?
Atomicity of an element is
a measure of total number of atoms present in a molecule
. Example, an oxygen molecule contains two oxygen atoms. Therefore, the atomicity of oxygen is 2.
What are the two uses 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 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 3 uses of radioactive isotopes?
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. Used in nuclear medicine for nuclear cardiology and tumor detection. Used
to study bone formation and metabolism
.
Can isotopes be created?
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 isotopes explain?
Isotopes are
members of a family of an element that all have the same number of protons but different numbers of neutrons
. … Every element has its own number of isotopes. The addition of even one neutron can dramatically change an isotope's properties. Carbon-12 is stable, meaning it never undergoes radioactive decay.
How do isotopes work?
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of
neutrons
giving each elemental isotope a different atomic weight.
How do we use isotopes in everyday life?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are
used as tracers for diagnostic purposes
as well as in research on metabolic processes.
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. Every chemical element has one or more isotopes.
How do you write isotopes?
To write the symbol for an isotope,
place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol
. The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl.
What is Isodiapher example?
A set of nuclides which has a different number of protons and neutrons but there exists the same difference between the protons and neutrons are isodiaphers. For example,
Thorium -234 and Uranium -238
are considered as isodiaphers. Hence, Thorium -234 and Uranium -238 are considered as isodiaphers.”
