Question

What is atomicity? calculate the atomicity of cuso4 HCl pbno3 s8 na

Answer 1

Answer:

Atomicity is defined as the total number of atoms in a molecule

Atomicity of Pb(NO₃)₂

=  Number of Pb-atoms +  Number of N-atoms +  Number of O-atoms

= 1 + 2 + 6

= 9

Atomicty of CuSO₄

= Number of C-atoms + Number of S-atoms + Number of O-atoms

= 1 + 1 + 4

= 6

Atomicity of HCl

= Number of H-atoms +  Number of Cl-atoms

= 1 + 1

= 2

S8 atomicity

=8 called as polyatomic

Na Atomicity

Sodium = 1

Answer 2

the number of atoms in the molecules of an element is atomicity

in cuso4 cu atomicity is 1 and oxygen atomicity is 4

in pbno3 pb atomicity is 1 and no3 atomicity is 3
