Modern periodic table, periodic properties

Each column in the table is referred to as a period. A period’s elements all have the same number of orbitals. This progression begins with a single orbital in the top row and ends with seven orbitals in the bottom row. Each row adds an orbital. Physical properties of elements belonging to the same era […]

The Periodic Law asserts that when the elements are placed in increasing atomic number order, the physical and chemical properties of the elements recur in a systematic and predictable manner, which is known as the periodic table. Many of the characteristics recur on a regular basis. When the components are correctly ordered on the table,

Alternatively, the oxidation state of an element can be defined as the degree of an element’s ability to lose electrons from its valence shell in a chemical compound. This is also referred to as the degree of oxidation of the element in question. During the formation of their compounds, transition elements exhibit a wide range

Alkaline earth metals are a group of six chemical elements in the periodic table. There are six elements in this group: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). At ordinary temperature and pressure, all of the elements have extremely similar properties: they are all lustrous, silvery-white, moderately reactive metals.

Magnetism is a class of physical qualities that are mediated by a magnetic field, and it refers to the ability to generate attractive and repulsive phenomena in other entities by the application of a magnetic field. Magnetic fields are created by electric currents and the magnetic moments of elementary particles, which operate on other electric

“Flint” or “hard stone” are the Latin words silex and silicis, which mean “flint” and “hard stone,” respectively. Jöns Jacob Berzelius, a Swedish chemist, was the first to isolate and describe amorphous elemental silicon as an element in 1824. He named it silicon. In 1811, impure silicon had already been discovered and was being used.

The term isotope is derived from the Greek words isos (“equal”) and topos (“place”), which signify “the same location.” As a result, different isotopes of a single element occupy the same spot on the periodic table. Margaret Todd, a Scottish doctor and journalist, suggested the term to chemist Frederick Soddy in 1913. Isotopes Isotopes are

If two nuclides have the same neutron number N but differing proton numbers Z, they are isotones. Isotones, for example, have the same number of neutrons as boron-12 and carbon-13 nuclei. Similarly, because they all have 20 neutrons, 36S,  37Cl,  38Ar,   39K, and 40Ca nuclei are all isotones of 20. Despite its resemblance to

Carbon can be found in a variety of forms all over the planet, including 0.02% of the crust of the Earth itself, which is made up of carbon. Since carbon is so dissimilar to the other items in the group, it is the first thing that comes to mind when viewing the collection as a

Because of its unique properties, aluminium is one of the most commonly utilised metals in the industrial sector, and commercial production of the metal began in the late nineteenth century. The element is found in its natural state in combination with oxygen and other elements, and it is the third most prevalent metal in the
