Covalent network solids are held together by covalent bonds, forming a continuous network throughout the solid.

Metallic solids are held together by metallic bonds, which involve a 'sea' of delocalized electrons around positively charged metal ions.

Metallic solids are held together by metallic bonds, which involve a 'sea of electrons' that are free to move.

Antibiotics are primarily used to treat bacterial infections by inhibiting the growth of bacteria.

Antioxidants prevent oxidation, which can lead to spoilage and degradation of food quality.

Antioxidants prevent oxidation by neutralizing free radicals, thus protecting cells from damage.

Antioxidants prevent oxidation, which can lead to cellular damage and contribute to various diseases.
