The number of protons define what element we're dealing with.
There are C. 8 electrons.
Answer:
C. Cs < K < P
Explanation:
Electronegativity is the basically the tendency of an atom to attract electrons. The pauling scale is used to quantify electronegativity, the most electronegative element; fluorine has a value of 4.0 and francium, the least electronegative element has a value of 0.7
The electronegative values of the following elements are given as;
K = 0.82
Cs =0.79
P = 2.19
Arranging in order of increasing electronegativity, we have;
Cs < K < P. The correct option is;
C. Cs < K < P
If the humidity is high enough we may notice fumes rising out of the mixture containing Br solution. The fumes produced are HBr fumes.

What is hydrogen bromide? </h3>
Hydrogen bromide (HBr) is a corrosive and toxic gas. It can be fatal if it is inhaled. It is very corrosive to our respiratory system, to our eyes, and when it is in contact with skin. When it is in mist form or in a liquid form it will cause burns to all tissue if it falls upon.
<h3>Why fumes are produced? </h3>
Hydrogen Bromide is a highly irritating, corrosive, nonflammable gas having a pungent odor at room temperature. It will fume in air which have high humidity because formation of hydrobromic acid takes place; it is the diatomic molecule.
Under ordinary conditions hydrogen bromide is a gas but it can be converted into liquid. Hydrobromic acid is then formed after hydrogen bromide is dissolved in water.
Thus we concluded that the fumes produced when bromine solution is in contact with moist air is HBr fumes.
