# How many neutrons are in the nucleus of a chlorine-35 atom?

## How many neutrons are in the nucleus of a chlorine-35 atom?

18 neutrons
An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.

### How many protons neutrons and electrons does chlorine-35 have?

How many protons neutrons and electrons does chlorine 36 have?

Chlorine 36 (Cl-36) is the chlorine isotope whose nucleus consists of 17 protons and 19 neutrons. It is a cosmogenic radioisotope of chlorine with a trace half-life of 301,000 years in the environment, in a ratio of about 7 × 10-13 to 1 with stable isotopes.

Why is chlorine-36 used?

Chlorine-36 has been widely used for dating old groundwater. The 36Cl used for this purpose is produced in the atmosphere by the interaction of cosmic rays with argon atoms. Groundwater recharge carries the 36Cl into the subsurface where the radiometric “clock” is set.

## What is the stable daughter of chlorine-36?

List of isotopes

Nuclide Z Daughter isotope
Excitation energy
36Cl 17 36S
37Cl 17 Stable
38Cl 17 38Ar

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

Correspondingly, how many protons neutrons and electrons are there in a neutral atom of the isotope of chlorine named chlorine 35? Therefore, a neutral atom of chlorine contains 17 protons and 17 electrons.

#### How many electrons does a neutral atom of chlorine have?

Therefore, a neutral atom of chlorine contains 17 protons and 17 electrons. If we look up chlorine’s atomic mass number on the periodic table, it is 35 which indicates the sum of protons and neutrons in the nucleus.

How many isotopes of chlorine have the same atomic number?

Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons. Mass numbers of typical isotopes of Chlorine are 35; 37. Chlorine has two stable isotopes, 35Cl and 37Cl.

What kind of electron affinity does chlorine have?

Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity, behind only oxygen and fluorine.
