These two processes always happen together.
Even reactions without oxygen still involve oxidation and reduction.
Understanding redox reactions is essential for batteries, corrosion, metabolism, and
Equilibrium occurs when forward and reverse reactions happen at the same rate.
The system looks stable, but reactions continue microscopically.
Changing temperature or concentration shifts the equilibrium position.
Higher temperature increases particle speed. Higher concentration increases collision frequency.
Catalysts speed up reactions by lowering the energy needed for collisions to succeed.
Atoms are never destroyed, only reorganized.
Energy may be absorbed or released during this process. Reactions follow conservation of mass and charge.
In ionic bonds, electrons are transferred, creating charged ions that attract each other.
In covalent bonds, electrons are shared between atoms.
The type of bond affects strength, melting point, and electrical behavior.
Atoms are most stable when their outermost shell is full.
This is why atoms gain, lose, or share electrons during reactions.
Chemical behavior is mainly controlled by outer-shell electrons, not the nucleus.
The nucleus contains protons (positive charge) and neutrons (no charge).
Electrons (negative charge) move in regions around the nucleus called orbitals.
The number of protons decides the element, while
