Formation of covalent bonds

Question 1

How do atoms achieve stability?

Answer 1

Atoms can achieve stability by sharing electrons.

Question 2

How does a covalent bond form?

Answer 2

A covalent bond forms when two positive nuclei are held together by their common attraction for a shared pair of electrons.

Question 3

How does a covalent bond hold the atoms together?

Answer 3

The covalent bond holds the two atoms together by the common attraction both bonded nuclei have for the shared pair of electrons.

Question 4

What is a shared pair of electrons in a covalent bond attracted to?

Answer 4

In a covalent bond the shared pair of electrons is attracted to both nuclei of the bonded atom.

Question 5

What is a double covalent bond?

Answer 5

A double covalent bond consists of two shared pairs of electrons.

Question 6

What is a triple covalent bond?

Answer 6

A triple covalent bond consists of three shared pairs of electrons.

Question 7

Name the seven elements that exist as diatomic molecules through the formation of covalent bonds.

Answer 7

Fluorine(F2)
Chlorine(Cl2)
Oxygen(O2)
Hydrogen(H2)
Nitrogen(N2)
Bromine(Br2)
Iodine(I2)

Question 8

What is a molecular formula?

Answer 8

The molecular formula of a molecule shows the number and type of atoms joined together by covalent bonds.
