Answer:

2s² 2p⁵

There are seven valance electrons in fluorine.

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other.

Properties of fluorine:

1. it is yellow in color.

2. it is flammable gas.

3. it is highly corrosive.

4. fluorine has pungent smell.

5. its reactions with all other elements are very vigorous except neon, oxygen, krypton and helium.  

Electronic configuration of fluorine:

F₉ = 1s² 2s² 2p⁵

Valance electrons in fluorine are 2s² 2p⁵.

Valance Orbital configuration:

2s² 2p⁵

There are seven valance electrons in fluorine.

<h2>5.35 </h2>

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

We have

pH =  -  log(4.5 \times  {10}^{ - 6} )  \\  = 5.346787...

We have the final answer as
