Question

arrange the following elements as per instruction:- (a)mg,s,si,na(increasing metallic character).(b)n,ne,li,n(decreasing order of atomic size).(c)ne,o,n,e,f(decreasing order of electron affinity).(d)n,f,o,p(decreasing I.P)(e)mg,s,si,p(decreasing electronegativity).​

Answer 1

A) Na > Mg>Si>S
From left to right of a period , metallic character decreases
B) li>N>Ne
From left to right size decreases
C)F>O>N>Ne
D)F>N>P>O
E)S>Si>P>Mg
