This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
Each chemical element has a unique atomic number (Z— for "Zahl", German for "number") representing the number of protons in its nucleus. [4] Each distinct atomic number therefore corresponds to a class of atom: these classes are called the chemical elements. [5] The chemical elements are what the periodic table classifies and organizes.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
[83] [84] Brahma represents the abstract, while she represents action and reality. The variations in iconography of Sarasvati with various musical instruments The four hands hold items with symbolic meaning – a pustaka (book or script), a mālā (rosary, garland), a water pot and a musical instrument ( vīnā ).

Zodiac symbols (Vedic astrology) on the terrace of a temple in Kanipakam, Andhra Pradesh. Sidereal (Vedic) astrology shares the same system as Western astrology of linking zodiac signs to elements. In addition, in Vedic thought each of the five planets are linked to an element (with space as the fifth).
Mahakali represents darkness, pure tamas personified. Mahakali is one of the three primary forms of Devi. She is stated to be a powerful cosmic aspect (vyaṣṭi) of Devi, and represents the guna (universal energy) named tamas, and is the personification of the universal power of transformation, the transcendent power of time.

It is now often re-interpreted as the position of the mean lunar apogee as measured from the geocenter; variants of the Black Moon include replacing the mean orbit with a "true" osculating orbit or with an interpolated orbit; charting the empty focus of the Moon's orbit instead of the apogee; and measuring the desired point's barycentric or ...
As atomic number increases, shells fill with electrons in approximately the order shown in the ordering rule diagram. The filling of each shell corresponds to a row in the table. In the f-block and p-block of the periodic table, elements within the same period generally do not exhibit trends and similarities in properties (vertical trends down ...
