35,36 and 37. Chlorine has three stable isotopes chlorine-35, chlorine-36, chlorine 37 the most abundant of which are chlorine-35 and chlorine-37.
Cl mass number = 35.453
the answer is gas
Number of neutrons = Mass number - atomic number
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
the mass number is number of protons in an atom, plus the number of neutrons.

Isotopes. for example, a 35-Cl, 34-Cl, 36-Cl are all chlorines but with different neutrons, which would change their mass but not number of protons (what defines an element)
cl
gas
Two
Cl....
yes
It's a halogen
Chlorine has an atomic mass of 35.5 because the atomic mass of an element is the number of protons plus the number of neutrons. In chlorine, there are always 17 protons (the number of protons in an atom is what makes it whichever element it is), but it is possible to have different amounts of neutrons in the atom. These are called different isotopes of an element. In chlorine, there can be between 17 and 20 neutrons meaning the mass number can range between 34 and 37. The reason that it is written as 35.5 on the periodic table is because that is the average mass number.
concentrated hydrolic acid
the answer is 34.6 degrees Celsius
Reason for naming chlorine
