Atomic Structure and Chemical Bond

This lesson demonstrates that atoms are composed of a very small, positively charged nucleus, which is surrounded by a cloud of negatively charged electrons. Despite the nucleus being less than one ten-thousandth the size of the atom, it holds more than 99.9% of the atom’s mass. Additionally, the atoms in ceramic materials are bonded by chemical forces. A chemical bond is the attractive force that holds atoms or ions together. This attraction creates a more stable system compared to individual atoms. Valence electrons play a crucial role in forming these chemical bonds.
