Therefore, rubidium is dispersed in potassium minerals, similarly, gallium is dispersed in aluminum minerals but chemical element chromium and lead comparatively less abundant periodic table metal. For example, copper is much less abundant than rubidium. These elements are defined as dispersed elements of the environment. Some elements present in the crust in considerable amounts never occur in any concentrated form, pure form of an element dispersed from common minerals. The abundance of different types of chemical elements depends on the mode of occurrence or basic units of substances. It also composes some lighter chemical elements like sulfur, carbon, silicon, and oxygen. ![]() Geophysical evidence indicates that the core should contain elements with the properties of molten iron and some nickel (mean atomic number = 22). Primarily the crust describes a heterogeneous layer of silicates and oxides of different chemical elements, the mantle has a fairly homogeneous combination of different types of silicates, mainly of magnesium and iron. The several types of earth zones consist, the crust (∼36 kilometers in the depth of earth), the mantle (36 to 2900 kilometer), and the core (2900 kilometers to the center of the earth). Systematic data and other studies primarily describe that the earth consists of several zones bases on the density of the naturally occurring chemical elements. Each abundance data (earth, atmosphere, and surface water) is helpful in providing systematic scientific information of a chemical element with respect to its formation, properties, stability, and occurrence.Ī very small fraction of the mass of the earth’s crust (hydrosphere and atmosphere) is available for direct analysis and study of the composition, facts, and chemical properties of an element. The abundance of the elements on the earth is somewhat different from cosmic abundance. Spectroscopic analysis of the celestial bodies and analysis of materials provided knowledge about the abundance of elements over the whole universe or cosmos (cosmic abundance). The average relative content of an element in any natural system is called its abundance. Only 75 elements occur in the earth’s crust in a concentration greater than 10 -4 ppm. In this article, we study the origins, abundance, and chemical behavior or facts of the periodic table element. Element is the fundamental chemical material of matter or chemical compound now extends up to 112, with the scopes for further addition. ![]() All the periodic table elements are distributed throughout the entire universe and their isotopic compositions have been estimated by a wide range of chemical and spectroscopic studies on the sun and solar systems like stars, galaxies, nebulae, and interstellar space. Chemical element is a substance that cannot be decomposed into simpler substances by the common chemical processes in chemistry or chemical science.
