Question

An example X has an atomic no . 12 and mass no . 25 draw a diagram showing the distribution on of elation in the orbit and the nuclear composition of the neutral atom .. please give short answer​

Answer 1

at.no. is 12 means Mg atom 1s^2 2s^22p^6 3s^2 electronic configuration and mass no . is 25 means 12 proton and 13 neutron

Answer 2

fromulla is defined the problem x=atomic number then mass number = 12 then show the problem thenx=1 answer 1
