sorry your answer is wrong .according to aufbau principle the orbital with least electronic configuration should be filled first.so the outer most shell is P.2 electrons are present in outermost shell .the atomic number is 66.the electronic configuration is 2,8,18,26,8,2
sorry your answer is wrong .according to aufbau principle the orbital with least electronic configuration should be filled first.so the outer most shell is P.2 electrons are present in outermost shell .the atomic number is 66.t
18+8+2 = 28, not 26
And when did start teaching aufbau principle to 14 year olds??
i am class 10.in physics structure of atom ,aufbau principle is there
2,8,18,28,8,2
