Key Difference – Bond Energy vs Bond Enthalpy Both bond energy and bond enthalpy describe the same chemical concept; the amount of energy required to break apart a mole of molecules into its component atoms. This measures the strength of a chemical bond. Therefore it is also called bond strength. The bond energy is […]
Difference Between Unit Cell and Primitive Cell
Key Difference – Unit Cell vs Primitive Cell Unit cell of a lattice is the smallest unit that represents all the constituents in a crystal system and their arrangement. The unit cell is the smallest repetitive unit of a lattice. A primitive cell is the smallest possible unit cell of a lattice. Therefore, the […]
Difference Between Lattice and Unit Cell
Key Difference – Lattice vs Unit Cell A lattice is a regular structure made of many small units known as unit cells. A unit cell is the smallest representative unit of a lattice comprising of all the components that can be found repeating all over the lattice structure. The key difference between lattice and […]
Difference Between BCC and FCC
Key Difference – BCC vs FCC The terms BCC and FCC are used to name two different arrangements of crystalline structures. BCC stands for body-centred cubic structure whereas FCC stands for face-centred cubic structure. These are forms of cubic lattices. Therefore, these arrangements have spheres (atoms, molecule or ions from which the lattice is […]
Difference Between Hexagonal Close Packing and Cubic Close Packing
Key Difference – Hexagonal Close Packing vs Cubic Close Packing The terms Hexagonal closed packing (HCP) and cubic close packing (CCP) are used to name two forms of arrangements in chemical geometry. These terms explain the arrangement of atoms, molecules or ions in lattices (regular arrangements). When describing these arrangements, the constituents from which […]
Difference Between Covalency and Oxidation State
Key Difference – Covalency vs Oxidation State Atoms of different chemical elements are bonded with each other forming different chemical compounds. In the formation of a compound, the atoms are bonded to each other via ionic bonds or covalent bonds. Covalency and oxidation state are two terms that describe the state of these atoms […]
Difference Between Ionic and Molecular Solids
Key Difference – Ionic vs Molecular Solids Solid substances are compounds that exist in a solid state at a given temperature and pressure. Solid state means, the atoms, molecules or ions in that substance are tightly packed, avoiding the movement of those chemical species (unlike in liquids or gases). There are two main types […]
Difference Between Critical Point and Triple Point
Key Difference – Critical Point vs Triple Point Critical point and triple point are terms used to explain temperatures and pressures at which two or more phases of substances can coexist with each other. The critical point is the condition at which the liquid and vapour phase of the same substance coexist. The triple […]
Difference Between Physical and Chemical Equilibrium
Key Difference – Physical vs Chemical Equilibrium An equilibrium state describes the concentrations of reactants and products in a reaction mixture in a closed system. An equilibrium can take place only in a closed system. In equilibrium, the concentrations of reactants and products remain at constant values. If the amount of reactants or products […]
Difference Between STP and Standard Molar Volume
Key Difference – STP vs Standard Molar Volume The term STP stands for Standard Temperature and Pressure. The IUPAC gives 273.15 K (0°C or 32°F) as the standard temperature and 105 Pa (1.00 atom or 1 bar) as the standard pressure. The standard molar volume is the volume of a mole of a substance […]
