b. Find valence electrons of X and Y
c. Find valency of each element
d. Is element Xa metal or a non-metal? Justify your answer​

Answer 1

a. 12X24= 2,8,2

17Y35 = 2,8,7

b. Valence electrons in 12X24 is 2 and in 17Y35 is 7

c. Valency is 2 and 1

d. X is metal and Y is non metal

X = Magnesium , Y = Chlorine
