Write down the el
⇒ The atomic number of carbon = 6
The electronic configuration of 6C = 2,4
⇒ The atomic number of lithium = 3
The electronic configuration of 3Li = 2,1
⇒ The atomic number of fluorine = 9
The electronic configuration of 9F = 2,7
⇒ The atomic number of nitrogen = 7
The electronic configuration of 7N = 2,5
⇒ The atomic number of oxygen = 8
The electronic configuration of 8O = 2,6
Among the given elements, fluorine has highest non-metallic character (most electronegative element).
All the given elements have total two shells present in them which means all the elements belong to the same period (period 2).
⇒ The non-metallic character (electronegativity) increases as we move from lithium to fluorine in a period.
⇒ Hence, among the given elements, fluorine has the highest tendency to accept electrons.
⇒ Thus, fluorine has the highest non-metallic character.
Note: More easily an element accepts electrons, higher will be its non- metallic character (electronegativity)
