Which statement best describes how electrons fill orbitals in the periodic table?
Electrons fill orbitals in order of their increasing energy from left to right.
Electrons fill orbitals in order of their increasing energy from right to left.
Elements fill orbitals in order of increasing energy from top to bottom in each gro
Elements fill orbitals in order of increasing energy from bottom to top in each gro

3)Electrons fill orbitals in order of their increasing energy from    ...top to bottom in each group

in the periodic table...

Each element's atomic mass and atomic number increases, as you can see on the periodic table, when you are going from left to right, then to the next                         period (horizontal line).

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
