Question

An isotope Q has 18 neutron and mass number of 34 write an electronic arrangement

Answer 1

Answer:

Mass Number = No. of protons + No. of neutrons

34 = No. of protons + 18

No. of protons = 34 - 18 = 16

Also, No. of protons = No. of electrons

So, no. of electrons is also 16

Electronic configuration in KLMN form - 2,8,6

Electronic configuration in spdf form - 1s², 2s², 2p⁶, 3s², 3p⁴
