Chemical Bonding Quiz pt2

What does ionic bonding involve?

• Sharing of electrons

• Transfer of electrons

• Sharing of protons

• Transfer of protons

In ionic bonding, what happens to the electrons?

• One element loses electrons and the other gains electrons

• Both elements share electrons equally

• Electrons are shared among all atoms

• Electrons are not involved

What does covalent bonding involve?

• Transfer of electrons

• Sharing of electrons

• Transfer of protons

• Sharing of protons

In covalent bonding, why do atoms share electrons?

• To lose electrons

• To gain electrons

• To reach a stable configuration

• To become ions

What is the main idea of the Octet Rule?

• Atoms will gain or lose enough electrons to make them isoelectronic with a noble gas.

• Atoms will gain or lose protons to make them isoelectronic with a noble gas.

• Atoms will gain or lose neutrons to make them isoelectronic with a noble gas.

• Atoms will gain or lose electrons to make them isoelectronic with a halogen.

According to the Octet Rule, how many electrons will be in the valence shell of most atoms, except for hydrogen and helium?

• 6

• 8

• 10

• 12

What is the purpose of Electron Dot Structures?

• To show the number of protons in an atom

• To show the number of neutrons in an atom

• To show the number of valence electrons in an atom

• To show the number of atoms in a molecule

How must valence electrons be labeled in Electron Dot Structures?

• In a straight line

• Randomly around the element symbol

• In pairs around the element symbol

• In a circle around the element symbol
