Question

Match the following questions with their answers based on the diagram below.

1.How many electrons are in the n = 2 shell of the oxygen atom before bonding?
2. What is the maximum number of electrons an oxygen atom can hold in its outer energy level?
3. How many total electrons are there in a water molecule?
4. How many electrons are being shared between the atoms in this molecule?
5.How many bonds exist in this molecule

two bonds
ten electrons
four electrons
eight electrons
six electrons

Answer 1

There are 6 electrons in the n=2 shell of the oxygen atom before bounding

There are 8 electrons an oxygen atom can hold in its outer energy level

There are 10 electrons in a water molecule

There are 4 electrons being shared between the atoms (assuming it's a water molecule)

There are 2 bonds existing in this molecule

Answer 2

I couldn't answer questions 4 and 5 since there was no image attached! I hope it helps!

Step-by-step explanation:

1. There are six electrons in the n shell of the oxygen before bonding.
2. The maximum number of electrons that an oxygen atom can hold in its outer energy level is eight electrons.

3. There are ten electrons in a water molecule.
