Chemistry: Understanding Compounds

Study Notes

Carbon monoxide is a compound made of oxygen and carbon atoms.
Compounds are made of different types of atoms, while molecules are made of the same type of atoms.
Ionic bonds form when one atom transfers an electron to another, forming ions with opposite charges.
Covalent bonds form when atoms share electrons.
Ionic compounds are made of ions and have a rigid crystalline structure, high boiling and melting points, and are good electricity conductors.
Covalent compounds are made of atoms that are held together by weak covalent bonds and are poor electricity conductors.
Pure substances can be categorized as either elements or compounds.
Elements are made of the same type of atom and cannot be broken down into simpler particles.
Compounds are made of different atoms and can be broken down into their primary elements.
Sodium chloride is an example of an ionic compound, while carbon dioxide is an example of a covalent compound.
Elements and compounds have unique properties that are different from those of their constituents.
Compounds are made of elements, and elements combine to make compounds.
In nature, it is difficult to find chemicals as pure elements.
Ionic compounds have higher boiling and melting points and are good electricity conductors, while covalent compounds have weaker bonds and are poor electricity conductors.
Examples of elements include helium, chlorine, oxygen, and neon, while examples of compounds include carbon dioxide, sodium chloride, water, and methane.
The properties of compounds are different from those of their constituents.
Sodium chloride is an example of a compound made of sodium and chlorine, which have distinctly different properties when combined.
