Chemical Bonding Quiz

What is the purpose of writing the Lewis Structure for elements in ionic bonding?

• To show the number of protons in the nucleus

• To show the number of neutrons in the nucleus

• To show how many electrons are in the atom’s outermost energy level

• To show the atomic mass of the element

What does the oxidation number indicate in ionic bonding?

• The number of protons in the nucleus

• The number of neutrons in the nucleus

• What the element is likely to do - lose or gain electrons and how many

• The atomic mass of the element

What must be done to ensure the charges add up to zero in ionic bonding?

• Decide how many atoms of each element are needed

• Add more protons to the nucleus

• Change the atomic mass

• Increase the number of neutrons

What is the role of arrows in the Lewis Structure for ionic bonding?

• To show the number of protons

• To show which element is donating the electron(s)

• To indicate the atomic mass

• To show the number of neutrons
