In an atom, the mass of total positive charge present is 7348 times to that of the mass of a negatively charged particle. What is the atomic number of the element? `(m_(e )= 9.1xx 10^(-31)kg, m_(p)= 1.67xx 10^(-27)kg)`.

Answer

4

Explanation

Mass of total positive charge (proton)
= `7348 xx `Mass of negative particle (electron)
= `7348 xx 9.1 x 10^(-31)` kg total mass of proton
Total number of protons present =`(7348 xx 9.1 xx 10^31)/ (1.67xx10^27)`
= 4
Total number of protons atomic number = 4
Hence, the correct answer is 4.
