Answer: Explanation:Now the reason for existence of isotopes can be explained by
unstability of elements
. Some elements are unstable so they emit neutrons in form of some radiation e.g. 14C and 13C are unstable and so they continuously emits neutrons in the form of radiation.
What are the main features of isotopes?
1. Basic principles. 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 is the cause of isotopes?
This can be done by
firing high-speed particles into the nucleus of an atom
. When struck, the nucleus may absorb the particle or become unstable and emit a particle. In either case, the number of particles in the nucleus would be altered, creating an isotope.
What are 2 examples of isotopes?
Isotope Examples
Carbon 12 and Carbon 14
are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth's crust. Both have long half-lives.
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.
What are isotopes give an example?
Isotopes:
the atoms of the same element which have the same atomic number Z but differ in their mass number A are
called isotopes. Example: Hydrogen has three isotopes ( 1 1 H , X 1 1 X 2 1 2 1 H , X 1 3 X 2 1 2 3 H ) , Protium, Deuterium, Tritium.
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, carbon-14, carbon-13, and carbon-12 are all isotopes of carbon.
What are the types of isotopes?
There are two main types of isotopes, and these are
radioactive isotopes and stable isotopes
. Stable isotopes have a stable combination of protons and neutrons, so they have stable nuclei and do not undergo decay.
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.
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).
How do you tell if it's an isotope?
Look up at the atom on the periodic table of elements and find out what its atomic mass is.
Subtract the number of protons from the atomic mass
. This is the number of neutrons that the regular version of the atom has. If the number of neutrons in the given atom is different, than it is an isotope.
What is an isotope in your own words?
An isotope of a chemical element is
an atom that has a different number of neutrons
(that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom's nucleus.
What is the difference between an element and isotope?
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 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 are isotopes used in real life?
Among such prevalent uses and applications of radioisotopes are, in
smoke detectors
; to detect flaws in steel sections used for bridge and jet airliner construction; to check the integrities of welds on pipes (such as the Alaska pipeline), tanks, and structures such as jet engines; in equipment used to gauge thickness …
Do all elements have isotopes?
All elements have isotopes
. There are two main types of isotopes: stable and unstable (radioactive). … Some elements can only exist in an unstable form (for example, uranium). Hydrogen is the only element whose isotopes have unique names: deuterium for hydrogen with one neutron and tritium for hydrogen with two neutrons.
