How many electrons does carbon lack in its outer shell? 1 2 3 4

The correct answer is 4.

Explanation-

The atomic number of carbon is 6. Its electronic configuration is 2,4

The electronic configuration depicts that k shell of the carbon atom contains 2 electrons. The outer shell or the valence shell contains 4 electrons.

Every atom wants to possess 8 electrons in its valence shell in order to become stable.

Thus, the number of electrons lacked by carbon atom = 8-4

                                                                                               = 4

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
