Question

Two monoatomic cations x+and y2+' are isoelectronic then select the correct statement: (Both elements are consecutive) (A) Both element x and y have same number of electrons (B) Total number of valence electrons are more in element x, than elementy (C) Total number of valence electrons are more in element y, than element'x' (D) Both (A) and (B) are correct ​

Answer 1

Answer:

(c)

Step-by-step explanation:

as both x+ and y2+ are isoelectronic they will have same no. of electrons

let no. of electrons in x+ be a

no. of electrons in x= a+1

no. of electrons in y= a+2

therefore y has more electrons than x

therefore y has more valence electrons than x
