What is the main reason atoms bond?

• To increase reactivity

• To form ions

• To release energy

• To gain stability

What is the relationship between stability and energy in atoms, ions, or compounds?

• Stability is not related to energy

• Energy has no effect on stability

• Higher energy states are more stable

• Lower energy states are more stable

Which type of elements primarily form covalent bonds?

• Transition metals

• Nonmetallic elements

• Noble gases

• Metallic elements

What is the purpose of sharing valence electrons in covalent bonds?

• To acquire noble gas configuration

• To form ionic compounds

• To decrease stability

• To increase energy levels

What type of bond results from sharing valence electrons?

• Covalent bond

• Hydrogen bond

• Metallic bond

• Ionic bond

What is the term for a single covalent bond?

• Gamma bond

• Sigma bond

• Beta bond

What type of bond forms when two pairs of electrons are shared between two atoms?

• Single covalent bond

• Double covalent bond

• Triple covalent bond

• Pi bond

What is the term for the distance between two bonded nuclei at the position of maximum attraction?

• Ionic radius

• Electron cloud

• Bond length

• Atomic radius

What occurs when a bond between atoms in a molecule forms?

• Energy is absorbed

• Energy is released

• Energy is converted to mass

• Energy remains constant

In which type of reaction is more energy released during product bond formation than is required to break bonds in the reactants?
