Description : The most electronegative element among the following is - (1) sodium (2) bromine (3) fluorine (4) oxygen
Last Answer : (3) fluorine Explanation: Fluorine is the most electronegative element, while francium is one of the least electronegative.
Description : The most electronegative element among the following is – (1) Fluorine (2) Sodium (3) Chlorine (4) Oxygen
Last Answer : (1) Fluorine Explanation: Electronegativity of the elements using the Pooling Scale is as follows: Fluorine: 3.98, Oxygen: 3.44, Chlorine: 3.16, and Sodium: 0.93. Electronegativity increases down the group and decreases down the period.

Description : Is nitrogen electronegative?
Last Answer : Nitrogen has a valence of 3 which attracts it to get electronsfrom other molecules..this attraction it has to complete it'soutermost layer is called electronegativity.
Description : Give reason: a) Metals are electropositive. b) Non-metals are electronegative. c) Even though hydrogen is a non-metal, it is electropositive. d) Sodium is electropositive.
Last Answer : a) Metals are electropositive. Electropositive element has the tendency to lose electrons and form cation.Metals are electron donors. Hence they are electropositive. b) Non-metals are ... is electropositive because donates electrons from last orbit to another element and becomes electropositive.
