The definition of an isotope is an element with similar chemical make-up and the same atomic number, but different atomic weights to another or others. An example of an isotope is
Carbon 12 to Carbon 13
. One of two or more atoms having the same atomic number but different mass numbers.
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 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 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.
What is isotope short answer?
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 identify an isotope?
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 some 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 three types of isotopes?
(The word isotope refers to a nucleus with the same Z but different A). There are three isotopes of the element hydrogen:
hydrogen, deuterium, and tritium
. How do we distinguish between them? They each have one single proton (Z = 1), but differ in the number of their neutrons.
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 the isotope symbol?
Isotope Notation
Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and
E
is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.
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 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 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.
How do you find the most common isotope?
The most common isotope can be found by
rounding the atomic weight found on the periodic table of elements to the nearest whole number
.
Which element has maximum number of isotopes?
Sulphur has 4 stable isotopes which are 32S,33S,34S and 36S. Hence we see that
Sn
has the highest number of isotopes among all options.
Why do all isotopes have the same properties?
Atoms of the same element that differ in their numbers of neutrons are called isotopes. … Different isotopes of an element generally have the same physical and chemical properties
because they have the same numbers of protons and electrons
.
