What is a Periodic Table?

  1. a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends.

who invented the periodic table?

many collections of scientists invented it.

Purification Characterisation of Organic Compounds class 11

  Purification  Characterisation of Organic Compounds  name of the chapter:  Purification  Characterisation of Organic Compounds  Content Provider: FIITJEE Lecturer from FIITJEE simple notes: Organic compounds extracted from a natural source or synthesized in the laboratory require purification. Various methods are used for purification and are based on the nature of the compound and the impurity present in it. The purity of a compound is ascertained by determining its melting point or boiling point or by chromatographic and spectroscopic techniques. Fraction distillation  can be defined as a process where the separation of a mixture takes place. A mixture of various components such as chemical components can be easily vaporized by heating them to a temperature more than their boiling point and forming different fractions. embedded pdf:

acids bases and salts pptx

 Acids Bases and Salts PPT   name of the chapter:       acids bases and salts Content Provider:            Student ( Dharani ) Acid Bases and Salts introduction by NCERT : You already know that acids are sour in taste and change the colour of blue litmus to red, whereas, bases are bitter and change the colour of the red litmus to blue. Litmus is a natural indicator, turmeric is another such indicator. Have you noticed that a stain of curry on a white cloth becomes reddish-brown when soap, which is basic in nature, is scrubbed on it? It turns yellow again when the cloth is washed with plenty of water. You can also use synthetic indicators such as methyl orange and phenolphthalein to test for acids and bases. In this chapter, we will study the reactions of acids and bases, how acids and bases cancel out each other’s effects and are much more interesting things that we use and see in our day-to-day life. Do Y...

Molar Mass and Atomic Mass and first 20 elements

 Molar Mass and Atomic Mass and first 20 elements  Molar Mass : In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. It is the mass of 1 mole of the substance or 6.022×10²³ particles, expressed in grams.   Atomic mass: The  atomic mass  is a weighted average of all of the isotopes of that element, in which the  mass  of each isotope is multiplied by the abundance of that particular isotope. ( Atomic mass  is also referred to as  atomic weight , but the term " mass " is more accurate.) Calculating Average  Atomic Mass:  Average  atomic mass  = f 1 M 1  + f 2 M 2  +… + f n M n  where f is the fraction representing the natural abundance of the isotope and M is the  mass  number (weight) of the isotope. The average  atomic mass  of an element can be found on th...
