Question

An element X (atomic no. 11) reacts with an element Y (atomic no. 17) to form a monovalent
halide.
(a) Identify the position of X and Y in group and period in the Periodic Table.
(b) State whether these elements are metal or non- metal.
(c) Describe nature of oxide of element X.
(d) Draw electron dot structure of the halide.
6. Two elements X and Y have atomic number 11

Answer 1

Answer:

Explanation:

a) The atom X is sodium (Na)

    The atom Y is Chlorine (Cl)

the compound formed is Sodium chloride (NaCl)

b)  The position of X is in the first group and the position of y is in the 17th group

c) the oxide formed by the element X will be: basic in nature

d) refer the attachment

Answer 2

Answer:

a)element X is sodium and element Y is chlorine so the position of element X will 1st group 3rd period and the position of element Y will be 17th group 3rd period

b)sodium is metal while chlorine is a non metal

c) the oxide formed will be sodium oxide which is strongly basic in nature

d) refer the diagram given below
