Chemistry Properties and Structure of Matter: Properties of Matter - Chemical Properties of Elements

This video tutorial introduces the chemical properties of elements, distinguishing them from physical properties. It explains the significance of the valence shell and the octet rule in chemical reactions. The formation of ions, including cations and anions, is discussed, along with the types of chemical bonds: metallic, covalent, and ionic. The video also covers the reactivity of elements, particularly with water and acids, and highlights exceptions to general rules. Finally, it provides sample exam questions to reinforce learning.
