Question

Oxygen atoms have six electrons in their outer shells. When 2 oxygen atoms bond they will form a ___ bond by ___ their electrons

a. covalent,sharing

b. ionic,transferring

c. covalent,transferring

d. ionic,sharing

Answer 1

(a)covalent,sharing is the correct answer

Answer 2

OXYGEN ATOMS HAVE SIX ELECTRONS IN THEIR OUTER SHELLS. WHEN TWO OXYGEN ATOMS BOND THEY WILL FORM A COVALENT BOND BY SHARING THEIR ELECTRONS.

• COVALENT BOND- A chemical bond accordant of the reciprocal sharing of one or more pairs of electrons connecting two atoms. These electrons are concurrently attracted by the 2 atomic nuclei. A chemical bond appears when the difference between the electronegativities of two atoms is just insignificant for an electron convey to occur to make ions.
• Oxygen has 8 electrons ( E.C. 2,2,4) so it would want to share 4 electrons with another oxygen atom to attain stability mutually.
