chemistry

________ molecules are found in nature as single atom elements

• polyatomic
• monatomic
• elemental
• diatomic

______ molecules are found in nature as pairs of two atoms of the same type covalently bonded together.

• Diatomic

• Monatomic

• Polyatomic

• Network

Which of the following types of elements can exist in monatomic form?

• alkali metals

• transition metals

• halogens

• noble gases

Why do bonds form?

• To fill the valence shell of electrons for the elements involved
• to release energy stored in the bonds
• because whenever you mix two chemicals, there will be a reaction
• because of attraction
