The number of electrons in an element X is 15 and the number of neutrons is 16. Which of the following is the correct representation of the element?

Any element is represented symbolically as:



Here mass number = 15 +16 =31


Atomic number = number of protons =15


Hence, the correct representation of the element with 15 electrons and 16 neutrons is .


Hence, the correct option is – A
