What are the 3 isotopes of oxygen?
The element oxygen has three stable isotopes: 16O, 17O, and 18O.
What are all the isotopes of chlorine?
Chlorine for example has two naturally occurring isotopes: Chlorine-35 and chlorine-37. Naturally occurring chlorine is 75 % Chlorine-35 and 25% chlorine-37. It has an average atomic weight of 35.5 amu.
What are the 3 isotopes of chlorine?
Chlorine has 9 isotopes with mass numbers ranging from 32 to 40. Only three of these isotopes occur naturally: stable 35Cl (75.77%)and 37Cl (24.23%), and radioactive 36Cl.
How many isotopes does chlorine have?
Chlorine has two stable isotopes chlorine-35 and chlorine-37with Chlorine-35 accounting for roughly 3 out of every 4 naturally occurring chlorine atoms. Chlorine-36 is also known naturally and is a radioactive isotope with a half life of about 30,000 years.
How many oxygen isotopes exist?
Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent). Several artificially prepared radioactive isotopes are known. The longest-lived, oxygen-15 (124-second half-life), has been used to study respiration in mammals.
Why does oxygen have 3 isotopes?
Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. For example, there are three isotopes of the element oxygen (O): Oxygen 16, 17, and 18. Each isotope of oxygen contains 8 protons, but differs in the number of neutrons.
How do you find the isotopes of chlorine?
Chlorine naturally exists as two isotopes, 17 35 Cl (chlorine-35) and 17 37 Cl (chlorine-37). The abundance of chlorine-35 is 75% and the abundance of chlorine-37 is 25%. In other words, in every 100 chlorine atoms, 75 atoms have a mass number of 35, and 25 atoms have a mass number of 37.
Why does chlorine have two isotopes?
All atoms which contain 17 protons are called chlorine atoms. Adding or removing a proton from an atom’s nucleus changes that atom’s atomic number and creates a different element. Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. The number after the name ‘chlorine’ is called the mass number.
What is Cl-35 used for?
Both Chlorine isotopes, Cl-35 and Cl-37, are used to study the toxicity of environmental pollutant and are usually supplied in the form of NaCl.
Why does chlorine have 2 isotopes?
All atoms which contain 17 protons are called chlorine atoms. Adding or removing a proton from an atom’s nucleus changes that atom’s atomic number and creates a different element. Chlorine-35 and chlorine-37 are both isotopes of the element chlorine.
Why is oxygen 16 an isotope?
Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and neutrons. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.
What’s the most common isotope of oxygen?
“Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.
What is the most common chlorine isotope?
Chemical and molecular properties. A neutral atom has the same number of electrons as protons.
What are the common ions of chlorine?
Chloride ion is the reduced form of chlorine atom.
Chlorine has two stable isotopes, 35Cl and 37Cl. These are its only two natural isotopes occurring in quantity, with 35Cl making up 76% of natural chlorine and 37Cl making up the remaining 24%.The longest-lived radioactive isotope is 36Cl, which has a half-life of 301,000 years.
What are the different types of isotopes?
Types of radioactive isotopes by origin (return to top)1) Long-lived radioactive nuclides Some radioactive nuclides that have very long half lives were created during the formation of the solar system (~4.6 billion years ago) and are still present in the earth.
