Question

Complete the below table:-

Elements	Protons	Electrons	Neutrons	Mass no.
17A35
24B52

Answer 1

An atom with the atomic number (Z) and atomic mass (A) can be represented as:-

_ZX^A.

Number of electrons in an atom = Number of protons= Z

Number of neutrons = A-Z.

so, by applying this fact we can fill the table as under:-

₁₇A³⁵ ,It means that number of protons= 17 = number of electrons

Number of neutrons = A-Z = 35-17=18 , and mass(A) =35, similarly we can do for the second molecule.
