# How many protons would chlorine 35 have?

## How many protons would chlorine 35 have?

17
A chlorine nucleus will contain: Number of protons Z = 17. Number of protons + neutrons A = 35. Number of neutrons N = 35 – 17 = 18.

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

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). Adding or removing a neutron from an atom’s nucleus creates isotopes of a particular element.

How many protons are present in iron?

26 protons
A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus.

### 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.

### 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 has 18 protons and 17 neutrons?

Name Chlorine
Atomic Mass 35.453 atomic mass units
Number of Protons 17
Number of Neutrons 18

#### Why is chlorine-36 not an isotope?

Chlorine has two stable isotopes and one naturally occurring radioactive isotope, the cosmogenic isotope 36Cl. Its half-life is 301,300 ± 1,500 years. Cl decays primarily (98%) by beta-minus decay to 36Ar, and the balance to 36S….Chlorine-36.

#### 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.
