In an atom there are four orbits, the maximum number of electrons in this atom will be -

(B) neon Atomic number of carbon = 6 Electronic configuration of carbon = 2, 4 When carbon forms four covalent bonds by sharing its valence electrons with four univalent atoms (eg. Hydrogen), it...

The correct answer is (C) five

(b) increases

(c) two extra neutrons and no extra electron

 3d10 & 4d10 = 20.

5-electrons.......

1 electrons....

1s2 ,2s2 ,2p6 ,3s2 ,3p6 ,4s2 ,3d10,4p6 = 36 electrons can accommodated.

The correct answer is (D) 8

The electric fields bind the atoms to neutral entity. Fields are caused by excess charges. There can be no excess charge on the inter surface of an isolated conductor.
