Question

How many types of elements are there according to automicity​

Answer 1

Answer:

(iii) Triatomic molecules : The molecules consisting of three atoms, e.g., 03 (Ozone molecule). (iv) Tetratomic molecules : The molecules consisting of four atoms, e.g., P4 (Phosphorus molecule). (v) Polyatomic molecules : The molecules consisting of more than four atoms, e-g; S8 (Sulphur molecule).

Answer 2

Example. Hydrogen (H2), nitrogen (N2), oxygen (O2), chlorine (Cl2), bromine (Br2), and iodine (I2), all have 2 atoms each in their molecules. So, the atomicity of hydrogen, nitrogen, oxygen, chlorine, bromine and iodine is 2 each. Atomicity of some common elements.

There is a simple way to determine the atomicity of any element. It can be determined as a ratio of molecular mass and atomic mass. For example, using the case of oxygen molecule, the molecular mass is 32 (= 2x16), while the atomic mass is 16. If we divide the two, we get atomicity as 2 (=32/16).
