Classification of Elements and Periodicity

In chemistry, a silicate is any member of the silicate family of anions, which is composed of the elements silicon and oxygen. The orthosilicate SiO44-, metasilicate SiO32-, and pyrosilicate Si2O76-  are all members of the silicate family. In addition to such anions, the term is used to refer to any salts of such anions such […]

Group VIIA, the next-to-last column of the periodic table, contains six elements. As one might imagine, these elements share several characteristics. They all form diatomic molecules (H2, F2, Cl2, Br2, I2, and At2) and negatively charged ions (H-, F-, Cl-, Br-, I-, and At-). When discussing the chemistry of these elements, hydrogen is distinguished from

In chemistry, an orbital is a mathematical depiction of the wave-like activity of an electron pair, or electron. Orbitals are also referred to as electron orbitals or atomic orbitals. Depending on the energy of its electrons, each orbital type has a particular form. There are three different sorts of orbital types. Let’s have a look

The periodic table represents an arrangement of the chemical elements based on their atomic number so that the periodic properties of the elements (i.e. the chemical periodicity) can be made clear. The periodic table was not  recognized until the second decade of the 20th century that the arrangement of elements in the periodic system is

The electrical characteristics of semiconductors are unique. A conductor is something that conducts electricity, while an insulator is something that doesn’t. Semiconductors are materials that have properties that fall in the middle of the spectrum. Resistivity is a measurement of electrical properties. Gold, silver, and copper are good conductors of electricity because they have low

Calcium oxide has been known since prehistoric times. The Roman writer Cato the Elder (234 – 149 BC) documented one way of manufacturing the compound in 184 BC. By the early fifteenth century, many Europeans were employing calcium oxide (usually referred to as lime) in the construction of structures. The Scottish scientist Joseph Black (1728–1799)

The lanthanides are part of the periodic table, starting from the element lanthanum to lutetium. The atomic number of the elements starts from number 58 to 71. It is the first series in the periodic table that belongs to rare-earth metals. The magnetic properties of the lanthanides make them an important group of elements to

Physical properties are significant in identifying one material from another. Physical characteristics are frequently considered to be a broader category than mechanical qualities in the study and application of metallurgy, however not all physical properties are interchangeable. The method of testing is the most effective way of distinguishing physical properties from mechanical properties in most

Periodic trends are particular patterns found in the periodic table that depict various aspects of a specific element, such as its size and electrical capabilities. Electronegativity, ionisation energy, electron affinity, atomic radius, melting temperature, and metallic character are all major periodic patterns. Periodic trends, which result from the periodic table’s arrangement, offer chemists with a

John Dalton, a physicist, developed the atomic theory of matter in 1804 and helped scientists quantify the mass of known elements. Sir Humphry Davy and Michael Faraday, two chemists, invented electrochemistry around the same period, which contributed to the discovery of new elements. By 1829, chemist Johann Wolfgang Doberiner had discovered that elements having comparable
