The key difference between electrovalent and covalent bond is that electrovalent bond occurs by transferring electrons from one atom to another whereas covalent bond occurs as a result of sharing valence electrons between atoms. An ionic bond is also called an electrovalent bond. Valence electrons, which are electrons located in the outermost shells of an atom, […]
Difference Between Free Radical and Ion
The key difference between free radical and ion is that the free radicals have one or more unpaired electron, but ions have paired electrons. We can explain the difference between free radical and ion from the basic properties of an ion and a free radical. An ion can occur as a molecule or atom with a charge […]
Difference Between Mendeleev and Modern Periodic Table
The key difference between Mendeleev and Modern periodic table is that the basis of the modern periodic table is mainly the electronic configuration of the elements, which we call as the atomic number whereas, in Mendeleev periodic table, it is the atomic mass of the elements. Let us see here what is Mendeleev periodic table […]
Difference Between Leptons and Quarks
The key difference between leptons and quarks is that leptons can exist as individual particles in nature whereas quarks cannot. Until the 20th century, people believed that atoms are indivisible, but the 20th century physicists discovered that the atom can be broken into smaller pieces, and all atoms are made of different compositions. Therefore, we […]
Difference Between Tap Water and Distilled Water
The key difference between tap water and distilled water is that tap water may contain impurities whereas distilled water does not contain impurities. Water covers more than 70% of the earth’ surface. A larger portion of water is in the oceans and seas, and that is about 97%. Rivers, lakes, and ponds have 0.6% of […]
Difference Between Hydrogen Bond and Ionic Bond
The key difference between hydrogen bond and ionic bond is that ionic bonding exists between permanent anions and cations, whereas hydrogen bonds exist between partial positive and partial negative charges. Chemical bonds hold atoms and molecules together. Bonds are important in determining the chemical and physical behaviour of molecules and atoms. As proposed by the […]
Difference Between Valence and Core Electrons
The key difference between valence and core electrons is that valence electrons participate in chemical bond formations while core electrons do not. Atoms are the building blocks of all existing substances. They are so tiny that we can’t even observe them with our naked eye. Generally, atoms are in the Angstrom range. Atom is made […]
Difference Between Proton and Electron
The key difference between proton and electron is that proton is a subatomic particle found in a nucleus of an atom, whereas electrons are particles orbiting the nucleus. Atoms are the building blocks of all existing substances. An atom contains a nucleus, which has protons and neutrons. Electrons circle around the nucleus in orbitals. In […]
Difference Between Electronegativity and Polarity
The key difference between electronegativity and polarity is that electronegativity is the tendency of an atom to attract the electrons in a bond towards it, whereas polarity means the separation of the charges. Polarity arises due to the differences in electronegativity. Therefore, these two terms are closely related terms. However, there is a distinct difference […]
Difference Between Allotropes and Isotopes
The key difference between allotropes and isotopes is that allotropes are considered at the molecular level whereas isotopes are considered at the atomic level. There are about 118 elements in the periodic table according to their atomic number. An element is a chemical substance that consists of only a single type of atoms; hence, they […]
