What is the atomicity of oxygen molecule and sulphur molecule?
Atomicity
The atomicity of oxygen is 2 and it exists as O2.
The atomicity of sulfur is 8 and it exists as S8.
Sulphur dioxide is a gas composed of one sulphur atom and two oxygen atoms.
a) Is sulphur dioxide a molecule of element or molecule of
compound?
b) What is the atomicity of sulphur dioxide?
c) What is the molecular mass of sulphur dioxide?
Sulphur is like oxygen which has 6 valence electrons. So, it can obtain octet by sharing two electrons like oxygen and make a molecule of 2 atoms. Then why a sulphur molecule is made of 8 atoms?
