Best Answer

Chlorine has an atomic number of 17. Thus, neutral chlorine will have 17 protons and 17 electrons. Chlorine's most common isotope is 35Cl, meaning it has 35 - 17 = 18 neutrons.

Since the question was about a chlorine molecule, shouldn't the answer be about Cl2? 34 p and 36 n

How many electrons neutrons and protons are in cluorine?

Chlorine exist as two isotopes(same number of electrons and protons but different number of neutrons), although there are traces of one more but we're not to sure. ~70% of Chlorine is Chlorine-35 which contains 17 electrons and 18 neutrons ~30% of Chlorine is Chlorine-37 which contains 17 electrons and 20 neutrons and ≤1% of Chlorine-36........

How many protons neutrons and electrons are in chlorine 39?

The number of protons and electrons is always the same as the atomic number, which for chlorine is 17. The number of neutrons is always the mass number minus the atomic number, which for this isotope is also 17.


Where are neutrons protons and electrons found in a cell?

Electrons are found in the nucleus while protons and neutrons are outside the nucleus.


How many neutrons and electrons in chlorine?

There are two main isotopes of chlorine. Every chlorine atom has 17 electrons where there are 18 and 20 neutrons in chlorine-35 and chlorine-37 respectively.


How many electrons does a chlorine atom have if it has 17 protons and 18 neutrons?

17 electrons. The number of protons and electrons is always the same.


What is the number of protons electrons and neutrons in one atom of chlorine 37?

Chlorine atoms always have 17 protons. The number of neutrons equals the mass number of the isotope named minus the number of protons: in this instance, 35 - 17 or 18.


How many neutrons does chlorine -35 have?

It has 18 neutrons. Its really simple, 35 is the mass number(A) i.e., the total number of neutrons and protons. We know atomic number(Z) of chlorine is 17. This is the number of protons. So A-Z will give us number of neutrons.
