What are the isotope of chlorine?

What are the isotope of chlorine?

There are two stable isotopes, 35Cl (75.77%) and 37Cl (24.23%), giving chlorine a standard atomic weight of 35.45. The longest-lived radioactive isotope is 36Cl, which has a half-life of 301,000 years.

What is the mass of isotope CL 35?

34.968 8527
Chlorine

Isotope Atomic mass (Da) Isotopic abundance (amount fraction)
35Cl 34.968 8527(3) [0.755, 0.761]
37Cl 36.965 9026(4) [0.239, 0.245]

What are the mass number of the two isotopes of chlorine?

Chlorine has two stable isotopes: Cl-35 and Cl-37 with atomic masses 34.96 and 36.95, respectively.

How many isotopes does chlorine have?

two
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.

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.

What is the mass of chlorine 37?

35.45 amu
About one quarter of all chlorine atoms have 20 neutrons, giving those atoms a mass number of 37….Sample Problem: Calculating Atomic Mass.

chlorine-35 0.7577 × 34.969 = 26.50 amu
chlorine-37 0.2423 × 26.966 = 8.957 amu
average atomic mass 26.50 + 8.957 = 35.45 amu

What is the mass of CL 37?

36.97u
“The atomic mass of chlorine-35 is 34.97u, and the atomic mass of chlorine-37 is 36.97u.

Why does chlorine have 2 isotopes?

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. Since all atoms of chlorine contain 17 protons, chlorine-35 and chlorine-37 differ in the number of neutrons each one has.

What is the heaviest isotope of chlorine?

Chlorine-37

General
Natural abundance 24.23%
Half-life Stable
Isotopes of chlorine Complete table of nuclides

What is the mass of chlorine-37?

What is the atomic weight of chlorine?

The answer to why chlorine has an atomic weight of 35.5 not 35 is because of something called isotopes. Isotopes are atoms with the same number of protons (in the case of chlorine that means 17 protons) but different numbers of neutrons.

What is the Amu of chlorine?

To find the atomic mass of chlorine, the atomic mass of each isotope is multiplied by the relative abundance (the percent abundance in decimal form) and then the individual masses are added together. The atomic mass of chlorine is 35.45 amu.

Why is chlorine called Cl2?

Chlorine is called Cl2 because it is a diatomic molecule. Diatomic means there are two atoms of the same elements in the molecule. There are other diatomic molecule, such as hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2).

What is chlorine mass number?

Chlorine (chemical symbol Cl) is a chemical element. Its atomic number (which is the number of protons in it) is 17, and its atomic mass is 35.45.
