The excited state electron configuration of carbon is 1s22s12p3. explain what will happen as the carbon atom returns to its ground state, and write the ground state electron configuration.

The ground state electron configuration of carbon is 1s22s22p2. An excited state electron configuration of carbon is 1s22s12p3. This is the state of carbon when it undergoes chemical bonding to form four covalent bonds, as in methane, CH4. However, the experimental evidence shows that all four bonds have the same energy, which can only be explained by the concept that the 2s and 2p orbitals hybridize to form four sp3 orbitals, each with one unpaired electron.

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later

Sorry i dont understand the question can you rephase it?
