Question

consider two elements x (atomic no 17) and y (atomic 20)
1 write the positions of these elements in the modern periodic table.
2 write the formula of the compound formed by the combination of x and y .
3 draw electron dot structure of the compound formed and state the nature of the bond formed between the two elements.

Answer 1

FIRST, X = Cl(2,8,7)

           Y = Ca(2,8,8,2)

1.  X:-  group - 17, period - 3

   Y:-  group - 2 , period - 4

2.  CaCl₂

3.  ionic bond

HOPE IT HELPS YOU......

SORRY FOR ELECTRON DOT STRUCTURE......
