Find out atomic number, mass number, number of electron and neutron in

1.	Find out atomic number, mass number, number of electron and neutron in an element 40 x 20 ?
Answer» The mass no. of x is 40 The atomic no. of x is 20 No. of proton is = Z – A = 40 – 20 = 20 No. of electron its (A) = 20 No. of proton is (A) = 20 For ⁴⁰X₂₀ _{Atomic number = 20} Mass number = 40 Number of electrons = number of protons = atomic number = 20 Number of neutrons = mass number - atomic number = 40 - 20 = 20

Find out atomic number, mass number, number of electron and neutron in an element 40 x 20 ?

Answer»

The mass no. of x is 40

The atomic no. of x is 20

No. of proton is = Z – A = 40 – 20 = 20

No. of electron its (A) = 20

No. of proton is (A) = 20

For ⁴⁰X₂₀

_{Atomic number = 20}

Mass number = 40

Number of electrons = number of protons = atomic number = 20

Number of neutrons = mass number - atomic number = 40 - 20 = 20
