Covalent Bonds

Question 1

Covalent Bond

Answer 1

The Sharing of two or more electrons between two adjacent atoms is known as a covalent bond.

Question 2

Molecule

Answer 2

Is the smallest chemical amount of a covalent bonded substance.

Question 3

Diatomic Molecules

Answer 3

Covalent Molecules formed by sharing of electrons between identical atoms are Diatomic Molecules.

Question 4

Elements that are Diatomic

Answer 4

H2, N2, O2, F2, Cl2, Br2, I2, At2.

Question 5

Single Covalent Bond

Answer 5

Results when one pair (two) of electrons is shared between adjacent atoms in a molecule.

Question 6

Multiple Covalent Bond

Answer 6

Result when more than one pair (two) of valence electrons are shared between two adjacent atoms.

Question 7

Double Covalent Bonds

Answer 7

are formed when two pairs (four) of valence electrons are shared between neighboring atoms in a molecules. All four Valence electrons effectively occupy the space between the two nuclei in a molecule having a double covalent bond.

Question 8

Triple Covalent Bond

Answer 8

are formed when three pairs (six) of valence electrons are shared between two atoms in a molecule.

Question 9

How do you know if a compound is Covalently bonded?

Answer 9

*If two nonmetals combine, It will be a

Question 10

Contributing Structure

Answer 10

Whenever more than one stable Lewis Structure can be drawn to represent a molecule (or Polyatomic ion), resulting Lewis Structure are known as Contributing Structures.
