Plasma

               Plasma               The forth state of matter Plasma is considered the fourth state of  matter . The other fundamental states of matter are liquids, solids, and gases. Typically, plasma is made by heating a gas until its electrons have sufficient energy to escape the hold of the positively charged nuclei. As molecular bonds break and  atoms  gain or lose  electrons , ions form. Plasma can be made using a laser, microwave generator, or any strong electromagnetic field. Although you may not hear much about plasma, it is the most common prevalent state of matter in the universe and it relatively common on Earth. What Is Plasma Made Of? Plasma is made of free electrons and positively charged  ions  (cations). Properties of Plasma Because plasma consists of charged particles, p...

Periodic table

                                   Periodic table ELEMENTS- Elements are pure from of matter that are made up of one type of atom. ·        DOBEREINER- Grouped all elements in three (triads). ·        NEWLAND- Observed that when elements are arranging in increasing order of their atomic mass. Every eighteen element beginning from any element resemble the first element in its physical and chemical properties. ·        DMITRI MENDLEVE- He is a Russian chemist gave the first periodic table of elements based on his law which states that “The properties of elements are the periodic functions of their atomic mass.”   ·        Modern periodic table was given by HENERY MOSELEY. Periodic table- A tabular form of elements in group and periods highlighting the regular trends in...
