Answer 1

Answer:

Neil Bohr ....................

Answer 2

Answer:

Neil Bohr

Step-by-step explanation:

In a snippet, electrons( negatively charged) revolve around the appreciatively charged nexus in a definite indirect path called routeways

or shells.

Each route or shell has fixed energy and these indirect routeways

are known as orbital shells.

The energy situations are represented by an integer( n = 1, 2, 3 …) known as the amount number. This range of amount numbers starts from the nexus side with n = 1 having the smallest energy position. The routeways

n = 1, 2, 3, 4 … are assigned as K, L, M, N …. shells and when an electron attains the smallest energy position, it's said to be in the ground state.

The electrons in a snippet move from a lower energy position to an advanced energy position by gaining the needed energy and an electron moves from an advanced energy position to a lower energy position by losing energy.
