## Lewis structure

In the Lewis structure of There are three bonds shown as the three parallel lines between the N atoms. This is a triple bond, with each bond formed by a pair of electrons, one from each N atom. Thus, this triple bond represents a total of 6 electrons.
Each N atom has two dots representing a lone pair. Making total number of electrons around each N = 8 and thus completing octet for both N. ## Lewis structure Sample Questions

Question 1: What does the three lines represent in Lewis structure of ?

a) Three lone pairs                     b) Three electrons
c) Triple bond                             d) Double bond

Explanation: In the Lewis structure of There are three bonds shown as the three parallel lines between the N atoms. This is a triple bond, with each bond formed by a pair of electrons, one from each N atom.

Question 2: How many of total nonbonding electrons are present in Lewis structure of .

a) 0                            b) 1
c) 2                            d) 4

Explanation: Each nitrogen atom has 5 valence electrons. Out of these 5, each N atom uses three electrons in bonding with each other and two electrons are left on both N atoms. Thus, total of 4 unpaired electrons are there in lewis structure of .

Question 3: What kind of bond is present in molecule?

a) Covalent bond                          b) Ionic bond
c) Co-ordinate bond                      d) None of the above

Explanation: N is a non-metal. Bond formed between two nonmetals is covalent and is formed by sharing of electrons. In Both N atoms share 6 electrons by forming a triple bond. Hence, the bond is covalent.

Question 4: What do the two dots on an atomic symbol represent in a lewis structure?

a) Single bond                         b) Lone pair
c) Double bond                        d) An unpaired electron

Explanation: The lone pair of an atom is represented by two solid dots on the  atomic symbol, in a lewis structure.

Question 5: How many triple bonds are there in lewis structure of a) 0                        b) 1
c) 2                        d) 3

Explanation: In a molecule two N atoms share 6 electrons with each other forming a triple covalent bond between them. Each bond is formed by a pair of electrons and thus 6 electrons give rise to a triple bond. In lewis structure the triple bond is represented by three solid parallel lines between two N atoms.

Question 6: How many bonding electrons are there in a) 2                        b) 3
c) 4                        d) 6

Explanation: A nitrogen atom has a total of 7 electrons, out of which there are 5 valence electrons. In a Molecule total electrons are 14 and valence electrons are 10. The three electrons from each nitrogen atom are shared with each other forming a triple bond between two N atoms, thus total bonding electrons in lewis structure of is 6.

Question 7: What are valence electrons-

a) Total electrons in an atom                         b) Electrons in outermost shell
c) Noble gases                                              d) Electrons in outermost subshell

Answer: Option b) Electrons in outermost shell

Explanation: Valence electrons are electrons present in the outermost shell of an atom, and can participate in the formation of a chemical bond with other atoms.

Question 8: Which of the following statements about lewis structure of is true?

a) There are 6 nonbonding electrons.                         b) There are 4 bonding electrons.
c) There are two lone pairs.                                        d) There are three triple bonds.

Answer: Option c) There are two lone pairs.

Explanation: Each nitrogen atom has 5 valence electrons. Out of these 5, each N atom uses three electrons in bonding with each other and two electrons are left on both N atoms. Thus, total of 4 unpaired electrons (two lone pairs) are there in lewis structure of .

Question 9: How many total valence electrons are present in ?

a) 3                         b) 5
c) 10                       d) 10

Explanation: Each nitrogen atom has 7 electrons, 5 of which are valence electrons. There are two N atoms in , and therefore 10 valence electrons.

Question 10: follows the octet rule?

a) True                        b) False

Explanation: Each N atom is surrounded by two dots and three solid lines, representing another 6 electrons in the triple bond. So each N is surrounded by 8 total valence electrons, completing the  octet and making it stable.

### How many bonding electrons are in the Lewis structure of n2?

A nitrogen atom has a total of 7 electrons, out of which there are 5 valence electrons. In a N2 Molecule total electrons are 14 and valence electrons are 10. The three electrons from each nitrogen atom are shared with each other forming a triple bond between two N atoms, thus total bonding electrons in lewis structure of is N2 6.

### What is the correct Lewis structure for N2?

In the Lewis structure of N2. There are three bonds shown as the three parallel lines between the N atoms. This is a triple bond, with each bond formed by a pair of electrons, one from each N atom. Thus, this triple bond represents a total of 6 electrons.

Each N atom has two dots representing a lone pair. Making total number of electrons around each N = 6 and thus completing octet for both N. ### How many triple bonds are in the Lewis structure for nitrogen gas, N2?

In a N2 molecule two N atoms share 6 electrons with each other forming a triple covalent bond between them. Each bond is formed by a pair of electrons and thus 6 electrons give rise to a triple bond. In lewis structure the triple bond is represented by three solid parallel lines between two N atoms.
