Question

State

2 n^{2}

rule of Bohr and Bury. Draw diagrams indicating the distribution of electrons in an atom of the elements having atomic number

8, 15 and 17

. Give the names and symbols of these elements.

Accepted Answer

The distribution of electrons in different energy shell of an atom is governed by a scheme known as Bohr-Burry scheme. According to this scheme; the maximum number of electrons that could be present in a shell is given by the rule $2 n^{2}$ , where n is the orbit number or energy level.

For example, For the first energy shell $1,$ hence the maximum number of electrons in the first energy shell is = $2 {(n)}^{2} = 2 {(1)}^{2} = 2 \times 1 = 2$

Oxygen is the element having atomic number $8$ . The electronic configuration of oxygen is $2, 6 .$

Distribution of electrons in atom is given by:

The phosphorous is the element having atomic number $15 .$ The electronic configuration of Phosphorous is $2, 8, 5 .$

Distribution of electrons in phosphorous is given by:

Chlorine is the element having atomic number $17 .$ The electronic configuration of Chlorine is $2, 8, 7 .$

Distribution of electrons in chlorine is given by:

Oxygen atom has atomic number $8$ and its symbol is $O$ .

Phosphorous atom has atomic number $15$ and its symbol is $P$ .

Chlorine atom has atomic number $17$ and its symbol is $Cl$ .
