Question

Arrange the following in the given order
(a) Decreasing ionic size, `Mg^(2+),O^(2-),Na^(oplus),F^(ɵ)`
(b )Increasing first ionisaiton energy :`Mg,Al,Si,Na`
(c ) Increasing bond length `F_(2),N_(2),Cl_(2),O_(2)`
(d) The order of their increasing size:
`Cl^(ɵ),S^(2-),Ca^(2+),Al^(3+)`

Answer 1

Correct Answer - NA
Size `Ca^(2+ lt Ar lt Cl^(-) lt S^(2-)`
