Find the total number of correct orders among the following.
(a) Order of electron affinity : `S gt O^(-)`
(b) Order of ionic radius: `AI^(3+) lt Mg^(2+) lt O^(2-)`
(c) Order of electronegativity: `Si lt P lt C lt N`
(d) Order of atomic radius: `O lt C lt S lt Se`
(e) Order of second ionization energy: `C lt N lt F lt O`
(f) Order of ionic radii : `S^(2-) lt CI^(-) lt K^(+) lt Ca^(2+)`

Answer

`005`

Explanation

(f) Correct order is `S^(2-) gt CI^(-) gt K^(+) gt Ca^(2+)`
