The correct option is A 1- D, 2-C, 3-A and 4-B
In case C-4, the number of electrons in the outer most orbit is 8.Thus the total number of electrons including 2 electrons in the inner orbit is 10. But the number of protons still remains the same .i.e. 6. Thus it becomes difficult for 6 electrons to hold back 10 electrons.
C+4 is achieved by losing 4 more electrons from the outermost orbit. In this case, the number of electrons in the outermost orbit is 0. Thus the total number of electrons is 2 (the first or inner orbit electron is 2). But the number of protons is the same i.e. 6. Thus force of attraction between 6 protons and 2 electrons becomes too high, which leads to unstable carbon atom.
