Question

State rules of Bohr and Bury.Draw diagram indicating the distribution of electrons in the atoms of the elements having atomic number 9,16,19.Give the names and symbols of these elements.
And pls draw a diagram.
Pls fast answer​

Answer 1

Answer:

The electrons first occupy the shell with the lowest energy i.e., closest to the nucleus. The first or the innermost energy shell (K or n = 1) can take only two electrons. The second shell (L or n = 2) can contain upto 8 electrons. From third shell (M or n = 3) onwards, the shells become bigger.

Answer 2

Answer:

In general, the maximum number of electrons that can be present in any shell is 2n2 where n is the number of energy shell. Thus, the first orbit (n = 1, known as K shell) can contain 2 × 12 = 2 electrons, the second orbit (n = 2, known as L shell) can contain 2 × 22 = 8 electrons. please make me brainslit please
