Because chlorine atoms occur as two isotopes: 35Cl and 37Cl. The first accounts for 75.76% of chlorine and the second for the rest so the [weighted] average mass is(75.76*35 + 24.24*37)/100 = 35.48 = 35.5, approx.
The atomic mass of chlorine is not 355 it is 35.5 (approx). So, if the molecular mass is 71 then the atomicity is 71/35.5 = 2.
Chlorine is a non meta element. Atomic mass of it is 35.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
The atomic mass of chlorine is not 355 it is 35.5 (approx). So, if the molecular mass is 71 then the atomicity is 71/35.5 = 2.
Chlorine is a non metal element. Chlorine atomic mass is 35.453.
the atomic mass of chlorine is 35.453
Chlorine is a meta element. Atomic mass of it is 35.
Chlorine is a non metal element. Atomic mass of it is 35.45.
Atomic Mass: 35.453
Chlorine has an atomic mass of 35.453.
Chlorine is a non meta element. Atomic mass of it is 35.
The relative atomic mass of chlorine is 35.5. The two main isotopes are chlorine-35 and chlorine-37.
The atomic mass for chlorine (Cl) is 17
Chlorine does not have atomic mass 5, so it cannot be "the only element that has a 5 atomic mass".
The atomic weight (not mass) of chlorine is now [35,446; 35,457]. I don't understand "no chlorine with mass exist in nature".
