What is an isotope simple 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.
What is an isotopes in chemistry?
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 an isotope GCSE?
Isotopes are forms of an element that have the same number of protons but different numbers of neutrons. N and 14 6C are not isotopes because although they have the same mass number, they are not the same element. If the number of protons changes, then it is a different element.
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 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.
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.
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 is the main cause of isotopes?
ISOTOPES’s MAIN CAUSE IS USING FOR PEOPLE. Isotopes exist because of instability caused in an atom. They continuously emit neutrons such as C has three isotopes in which 13 and C 14 are not state and continuously emir neutrons.
What are isotopes used for?
|32P||cancer detection and treatment, especially in eyes and skin|
|60Co||gamma ray irradiation of tumors|
|99mTc*||brain, thyroid, liver, bone marrow, lung, heart, and intestinal scanning; blood volume determination|
Why do isotopes have the same properties?
Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
How do you get isotopes?
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 relative formula?
The relative formula mass of a compound is calculated by adding together the relative atomic mass values for all the atoms in its formula. Moles are units used to measure substance amount. Chemistry (Single Science)
