The mass number of an isotope is the sum of its protons and neutrons. In this case, the isotope of chlorine has 25 protons and 17 neutrons. Therefore, the mass number is 25 + 17 = 42. Thus, the mass number of this isotope of chlorine is 42.

How many protons neutrons and electrons are in one most common isotope of chlorine?

Chlorine has the atomic number of 17. To keep it neutral then, it must have 17 protons and 17 electrons. Chlorine's most common isotope is 35Cl. That means it has 35 - 17 = 18 neutrons.


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........


What is the mass of a potassium atom with 20 neutrons?

Mass number = No. of protons + No. of neutrons = 19 + 20 = 39


What are you isotope or ion 17 protons 18 electrons 21 neutrons?

The element that has 17 protons is Chlorine, or Cl. The particular isotope of Cl that has 21 neutrons is called 38Cl, and is radioactive, having a half-life of 37.24 minutes. In this particular case, the number of electrons of this isotope are greater than its number of protons by one. That means that this isotope is also an ion, and is labeled as 38Cl-.


How many neutrons in chlorine 37?

The isotope Chlorine-37 (or denoted as 37Cl) has 20 neutrons per atom. 37 is the mass number (sum of number of neutrons and protons per atom) and we know that the atomic number for Cl irregardless of whichever isotope is 17, which means all Cl atoms have 17 protons. Therefore the number of neutrons for Chlorine-37 is 37 - 17 = 20.

An isotope of chlorine has 17 protons and 17 neutrons what is the mass number of that isotope of chlorine?

17 plus 17 equals 34. However, Chlorine-34 does not exist; the stable isotopes are Chlorine-35 and Chlorine-37.


An isotope of chlorine has 17 protons and 19 neutrons what is the mass number of that isotope of chlorine?

17 + 19 =36. This is 36Cl, which is non-stable with a half life 3.01 x 105 years. The two stable isotopes of chlorine are 35Cl and 37Cl, which have 18 and 20 neutrons respectively.


Where is chlorine's subatomic particles go?

Chlorine has 17 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a chlorine isotope = Mass number - 17
