The electronic configurations of three elements X, Y and Z are as follows:
X 2, 4
y 2, 7
z 2, 1
(a) Which two elements will combine to form an ionic compound?
(b) Which two elements will react to form a covalent compound ? Give reasons for your choice.
Answer :
(a) Ionic bond is formed by Y and Z because an ionic bond is formed when one of the atoms can donate electrons to achieve the inert gas configuration, and the other atom needs electrons to achieve the inert gas configuration. Here also Y has 7 and Z has 1 electron in their outermost shell, they would form an ionic bond.
(b) The two elements which will react to form a covalent compound are Y and Z.this is because a covalent bond is formed when both the reacting atoms need electrons to achieve the inert gas electron arrangement.
