What is maths formula when did it started ?

The development of mathematical formulas dates back thousands of years, beginning with ancient civilizations and cultures. The ancient Egyptians, Babylonians, Greeks, Indians, and Chinese all made significant contributions to the development of mathematical concepts and formulas.

For example, the ancient Egyptians had formulas to calculate the areas of triangles and rectangles. The Babylonians developed methods for solving quadratic equations. The Greeks made important contributions to geometry, including the famous Pythagorean theorem. Indian mathematicians introduced the concept of zero and developed algebraic techniques.

However, it was during the European Renaissance and the Scientific Revolution in the 16th and 17th centuries that the formalization and notation of mathematical formulas started to take shape. Mathematicians such as René Descartes, Pierre de Fermat, Isaac Newton, and Gottfried Wilhelm Leibniz played significant roles in developing algebra, calculus, and analytical geometry. They introduced symbolic notations and formulas to represent mathematical concepts and equations.

Since then, mathematicians and scientists from around the world have continued to expand and refine mathematical formulas, leading to the vast collection of formulas we have today. Mathematical formulas are essential tools for expressing relationships, solving problems, and advancing our understanding of the natural world.

The periodic table is a tabular arrangement of all the chemical elements based on their atomic structure and properties. It was first developed by Russian chemist Dmitri Mendeleev in 1869 and has since become a fundamental tool in the field of chemistry.

The table is organized in rows called periods and columns called groups or families. The elements are ordered by increasing atomic number, which represents the number of protons in the nucleus of an atom.

The periodic table has several important features. For example, elements within the same group or family have similar chemical and physical properties. This is because they have the same number of valence electrons, which are responsible for an atom’s chemical behavior. Elements in the same period have different numbers of electron shells, which affects their reactivity and bonding properties.

The periodic table is also used to predict the properties of elements that have not yet been discovered or synthesized. This is possible because the table reveals trends in atomic size, ionization energy, electron affinity, and other properties that are related to an element’s position within the table.

Overall, the periodic table is a vital tool for chemists and scientists who study the properties and behavior of chemical elements.

How Periodic table is arranged ??

The periodic table is arranged in a specific way based on the properties and characteristics of the elements. It is organized into rows, called periods, and columns, called groups or families.

The elements are arranged in order of increasing atomic number, from left to right and top to bottom. This means that the elements in the same row have the same number of electron shells, while the elements in the same column have the same number of valence electrons.

The periodic table is divided into several sections:

1. Alkali metals: Group 1 elements, such as lithium and sodium, are highly reactive metals that react readily with water to form alkaline solutions.
2. Alkaline earth metals: Group 2 elements, such as magnesium and calcium, are also reactive metals, but they are less reactive than alkali metals.
3. Transition metals: These are the elements in the middle of the periodic table, from groups 3 to 12. They are characterized by their variable oxidation states and ability to form colorful compounds.
4. Halogens: Group 17 elements, such as chlorine and fluorine, are highly reactive nonmetals that readily form salts with alkali metals.
5. Noble gases: Group 18 elements, such as helium and neon, are nonreactive gases that have complete outer electron shells.

In addition to these sections, the periodic table also includes the lanthanides and actinides, which are placed below the main table. These elements are part of the inner transition metals and have unique electronic configurations and properties.

Overall, the periodic table is arranged in a way that reflects the electronic structure and chemical properties of the elements. This arrangement is essential for predicting the properties and behavior of elements and their compounds.
