An alternative definition of electronegativity is Electronegativity= constant (I.E — E.A.) where I.E. is the ionization energy a

Kazeer [188]

Answer:

The electronengativity values of given elements is as follows.

Fluorine - 4

Chlorine -3

Bromine - 2.9

Iodine- 2.5

Explanation:

Electronegativity =consant (I.E-E.A)

The electron affinity and ionization energy values of the given elements is as follows.

(In attachment)

First we have to find the value of constant by using the fluorine atom to whom the electronengativity taken as "4".

Fluorine:

$4=constant[1678-(-327.8)]$

$Constant=0.0019942168$

By using this constant values we can find electronegatvity values of remaining elements.

Chlorine:

$Electronegativity=0.0019942168[1255+348.7]=3.1980\sim 3$

Therefore, electronegativity of chlorine is 3.

Bromine:

$Electronegativity=0.0019942168[1138+324.5]=2.91\sim 2.9$

Therefore, electronegativity of bromine is 2.9.

Iodine:

$Electronegativity=0.0019942168[1007+295.7]=2.59\sim 2.5$

Therefore, electronegativity of iodine is 2.5.

Compare how fast the rate of CO2 increase is in the last few hundred years with the rate of increase (or decrease, for that matt

Tcecarenko [31]

The rate of CO2 increase is in the last few hundred years is 10 times more with the rate of increase (or decrease, for that matter) in the preceding 400,000 years.

There are many possible reasons for this cause , some primary factors are listed below:

Increase in population
increased emission of green house gases, as we all know auto mobile industry is growing rapidly and this vehicles releases harmful gases like CO2, CO ,etc. and increases carbon % , this CO2 is a main gas component in green house effect.
Deforestation, as the amount of plant decreases the CO2 present in atmosphere increases, plants uses CO2 and sun lite to make their food via photosynthesis.
Increased emission of Industrial flue gases, etc.
