Key Difference – Mendeleev vs Moseley Periodic Table The periodic table of elements is the arrangement of all the known chemical elements in a table that represent their periodic trends. The chemical elements are arranged based on their atomic numbers. These chemical elements can be categorized in different ways; as metals, non-metals and metalloids, […]
Difference Between Percent Abundance and Relative Abundance
Key Difference – Percent Abundance vs Relative Abundance Percent abundance and relative abundance are percentage values of chemical elements that represent their occurrence in the environment. The key difference between percent abundance and relative abundance is that percent abundance gives the abundance of isotopes whereas relative abundance gives the abundance of chemical elements. The […]
Difference Between Unimolecular and Bimolecular Reactions
Key Difference – Unimolecular vs Bimolecular Reactions In chemistry, the term molecularity is used to express the number of molecules that come together to react in an elementary reaction. An elementary reaction is a single step reaction that gives the final product directly after the reaction between reactants. This means that the elementary reactions […]
Difference Between Monoxide and Dioxide
Key Difference – Monoxide vs Dioxide The terms monoxide and dioxide are used in the nomenclature of oxide compounds. An oxide is any chemical compound containing at least one oxygen atom bonded to another element. Sometimes the term oxide is used to name the oxide anion (O2-). Most of the elements can be found […]
Difference Between sp3d2 and d2sp3 Hybridization
Key Difference – sp3d2 vs d2sp3 Hybridization There are hypothetical structures known as orbitals in an atom in which electrons reside. Different scientific discoveries have proposed different shapes for these orbitals. Atomic orbitals can undergo a process known as hybridization. Hybridization of orbitals occurs in order to obtain suitable shapes required for chemical bonding. […]
Difference Between Acid Anhydride and Basic Anhydride
Key Difference – Acid Anhydride vs Basic Anhydride An anhydride is a chemical compound obtained with the elimination of a water compound from a parent compound. There are organic anhydrides and inorganic anhydrides classified based on the presence of C and H atoms. These anhydrides can be either acid anhydrides or basic anhydrides. Most of […]
Difference Between Bohr and Rutherford Model
Key Difference – Bohr vs Rutherford Model The concept of atoms and their structure was first introduced by John Dolton in 1808. He explained the laws of the chemical combination by considering atoms as invisible particles without a structure. Then in 1911, the New Zealand physicist Ernest Rutherford proposed that atoms consist of two […]
Difference Between Alkalinity and Hardness
Key Difference – Alkalinity vs Hardness Although water covers 71.1% of the earth’s crust, water everywhere is not the same. However, water is the only inorganic substance that can exist in all three physical states naturally as liquid water, ice, or water vapor. This is due to the variations in temperature. According to the […]
Difference Between Bohr and Quantum Model
Key Difference – Bohr vs Quantum Model The Bohr model and quantum model are models that explain the structure of an atom. Bohr model is also called Rutherford-Bohr model because it is a modification of the Rutherford model. Bohr model was proposed by Niels Bohr in 1915. Quantum model is the modern model of […]
Difference Between Universal Gas Constant and Characteristic Gas Constant
Key Difference – Universal Gas Constant vs Characteristic Gas Constant Gaseous phase is one of the three major phases matter can exist. It is the most compressible state out of the three states of matter. Only 11 elements out of other elements exist as gases under normal conditions. However, the “ideal gas law” gives […]
