What are the 2 isotopes of chlorine?

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 is the mass of a Cl 37 isotope?

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

What is CL 37 used for?

Cl-37 isotope is used for production of Sulphur-38 (38S isotope, S-38 isotope, Sulfur-38 isotope) radionuclide (radioisotope) for usage as a corrosion tracer (Industrial uses of radioisotopes and enriched isotopes);

What is the isotopes 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. All other isotopes have half-lives under 1 hour, many less than one second.

#### How many isotopes of chlorine has?

two
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.

How do you calculate the atomic mass of chlorine?

35.453 u
Chlorine/Atomic mass

How do you find the atomic mass of an isotope?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

## How do you find the atomic mass of chlorine-35?

The calculated average atomic mass is closer to 35 than to 37 because a greater percentage of naturally occurring chlorine atoms have the mass number of 35….Sample Problem: Calculating Atomic Mass.

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

What is the atomic mass of chlorine-35?

34.968852

Isotope Mass Abundance
35Cl 34.968852 75.77%
37Cl 36.965903 24.23%

What is the difference between Chlorine-35 and chlorine-37?

Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus).

### How many isotopes of chlorine are there in 17 CL?

Chlorine ( 17 Cl) has 25 isotopes with mass numbers ranging from 28 Cl to 52 Cl and 2 isomers ( 34m Cl and 38m Cl). There are two stable isotopes, 35 Cl (75.77%) and 37 Cl (24.23%), giving chlorine a standard atomic weight of 35.45.

What is the mass number of an atom of chlorine?

Chlorine (Cl) has isotopes with mass numbers ranging from 32 g mol −1 to 40 g mol −1. There are two principal stable isotopes, 35 Cl (75.77%) and 37 Cl (24.23%), found in the relative proportions of 3:1 respectively, giving chlorine atoms in bulk an apparent atomic weight of 35.5. Standard atomic mass: 35.453 (2) u

What is the isotope of chlorine with the longest half life?

There are two principal stable isotopes, 35Cl (75.78%) and 37Cl (24.22%), 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. All other isotopes have half-lives under 1 hour, many less than one second.

#### What is the global level of stable chlorine-37?

Stable chlorine-37 makes up about 24.23% of the naturally occurring chlorine on earth. Variation occurs as chloride mineral deposits have a slightly elevated chlorine-37 balance over the average found in sea water and halite deposits. Audi, G.; Kondev, F. G.; Wang, M.; Huang, W. J.; Naimi, S. (2017).
