What is the atomic number of Cl 2?

What is the atomic number of Cl 2?

Elemental chlorine gas (Cl2) is a yellow-green gas at room temperature and has a pungent odor similar to bleach even at very low concentrations. Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons.

How many neutrons are in CL?

18 neutrons
Atoms and isotopes 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. The different types of chlorine are called isotopes of chlorine.

How many protons are in Cl atoms?

17 protons
This is called the atom’s atomic mass number. For example, chlorine (CI) has an atomic number of 17. Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however.

What is the atomic number of Cl 1?

Chlorine is a chemical element with symbol Cl and atomic number 17.

How do you find the atomic mass of CL?

Expert Answer:

  1. The isotopes of chlorine, found in nature are in the ratio 3 : 1.
  2. The proportion in which the isotopes are found in the nature is always constant.
  3. Therefore, in any sample of chlorine, the average atomic mass will be,
  4. = (35 x 75/100) + (37 x 25/100)
  5. = 105/4 + 37/4.
  6. = 142/4.
  7. = 35.5 u.

What is the atomic number of chlorine 37?

). Its nucleus contains 17 protons and 20 neutrons for a total of 37 nucleons. Chlorine-37 accounts for 24.23% of natural chlorine, chlorine-35 accounting for 75.77%, giving chlorine atoms in bulk an apparent atomic weight of 35.453(2) g/mol….Chlorine-37.
