39. Atoms consist of a positively charged nucleus, which contains protons and neutrons, surrounded by
negatively charged electrons in energy levels or shells. The number of protons in an atom determines its
atomic number and defines its unique identity as an element. The electrons in an atom occupy specific
energy levels, and the outermost shell is known as the valence shell. Atoms gain, lose, or share electrons
to achieve a stable electron configuration, forming chemical bonds and giving rise to molecules.
