## How many neutrons are in an atom of chlorine?

17

## How do you find the number of neutrons in chlorine?

Each proton and neutron has a relative mass of 1 unit. Therefore we can subtract the number of protons from the atomic mass number in order to work out the number of neutrons. Chlorine has a mass number of 35, minus the 17 protons means that chlorine has 18 neutrons.

## How many protons neutrons and electrons are in chlorine 35 atom?

35-Chlorine has 17 Protons, and 18 Neutrons in its Nucleus. 37-Chlorine has 17 Protons, and 20 Neutrons in its Nucleus. Both, of these main & stable isotopes have a total of 17 Electrons.

## How many protons neutrons and electrons are in chlorine 37?

). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons.

## Is chlorine 37 stable?

There are only two stable isotopes: 35Cl and 37Cl with respective proportions of 75.76% and 24.24% (Berglund and Wieser 2011). The longest-lived radioactive isotope is 36Cl (half-life of 301,000 years); all other isotopes having half-lives of less than 1 h.

## 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).

## What is chlorine-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.

## What is the mass of CL 35?

## How do you calculate percent abundance?

As a percent, the equation would be: (x) + (100-x) = 100, where the 100 designates the total percent in nature. If you set the equation as a decimal, this means the abundance would be equal to 1. The equation would then become: x + (1 – x) = 1. Note that this equation is limited to two isotopes.

## What is the percent abundance of an isotope?

The relative abundance of an isotope is the percentage of atoms with a specific atomic mass found in a naturally occurring sample of an element.

## How do you figure out neutrons?

Since the vast majority of an atom’s mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).
