Question

An element X (atomic number 17) reacts with an element Y (atomic number 20) to form
a divalent halide.
a) Where in the periodic table are elements X and Y placed?
cltcastor
Classify X and Y as metal(s), non-metal(s) or metalloid(s).
What will be the nature of the oxide of element Y? Identify the nature of bonding
in the compound formed.
d) Draw the electron dot structure of the divalent halide.​

Answer 1

Answer:

a) X is of group 17 and period 3. Y is of group 2 and period 4.

b) X is non-metal and Y is metal.

c) the oxide of Y is basic. the nature of bonding is covalent.

d) Cl_Ca_Cl

Explanation:

Answer 2

X is chlorine (Cl) at. no. 17

Y is calcium (Ca) at. no.20

(a)

X is placed in halogen group 17

X is non metal

Y is metal

Y forms basic oxide

Compound of X and Y , that is, Calcium chloride is ionic compound.

(d)

electron dot structure is as follows
