Question

Two elements are represented as 17X^23 and 12Y^24. Which of these elements will lose and gain electrons

Answer 1

hey!

(10)( i) electronic configuration is done of electrons

so atomic no = no of protons

and no of protons= no of electrons

electronic configuration of element X = (17 ) = 2,8,7

electronic configuration of element Y= (12) = 2,8,2
______________________________


(ii) the names are cations and anions

___________________________

(iii) element X will again electrons as it needs 1 more electron to complete its octect it will become anion

element Y will loose electrons as it has only 2 electrons in its outermost shell it will become cation
