Question

1. An atom X has 2, 8,7 electrons in its shells. It
combines with Y having 1 electron in its outermost
shell.
(a) What type of bond will be formed between
X and Y ?
(b) Write the formula of the compound formed
(c) Would it be soluble in water ?
2. The electronic configuration of chloride ion is the
same as that of an argon atom. What is the difference
between the two ?
3. In the formation of the compound XY, an atom X
gives one electron to each Y atom. What is the nature
of bonds in XY2 ? Give two properties of XY2.
4. An atom has two electrons more than the noble gas
configuration. What type of ion will it form?
5. What are the conditions necessary for the formation
of covalent molecules ? Give their properties.​

Answer 1

Explanation:

1.a) it forms electrovalent bond

b)XY

c)no.,because after transfering of 1electron frm y to x . xbecomes stable so it is not soluble in water
