What is the correct noble gas configuration for magnesium?

a) ne [3s2
b) [ar] 3s2
c) [ne] 3s23p2
d) [he] 2s2

To determine the noble gas configuration, we need to identify magnesium's atomic number. Magnesium has an atomic number of 12. The nearest noble gas is neon which has an atomic number of 10. This means two electrons more is needed to complete magnesium's configuration. The answer hence is A. 

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
