Question

what is the atomic mass of chlorine ​

Answer 1

Answer:

35.453 u is the atomic mass of Chlorine

Answer 2

The atomic mass of chlorine is 35.435 unit.

Knowledge :-

The atomic number of chlorine is 17.

Trick to find atomic mass :-

At. mass even = 2n

At. mass odd = 2n + 1

Chlorine atomic number is 17.

Here, 17 is odd number.

So, Atomic mass = 2 × 17 + 1

= 34 + 1

= 35

Hence, 35 ≈ 35.435 unit.

• Weight of electron = 9.109 × ${10}^{ - 31}$ kg.

• Weight of proton = 1.67262 × ${10}^{ - 27}$ kg.

• The mass number of an atom is equal to the number of protons plus the number of neutrons.
