Lots of theories have been written, and experiments have been done for centuries by many renowned experts in chemistry.
There are three kinds of particles that have been found to form the basic structure of matter. They can be bent or hammered into different shapes. COMPOUNDS: When atoms of different elements combine chemically, they form compounds. Anytime, anyplace, any problem seek for Live Web Tutors help service.
These particles are called atomic and sub- atomic particles they include: PROTONS: Protons are positively charged particles. So far 115 elements are known out of which 92 are naturally- occurring in the earth’s crust. On the other hand non- metals are generally liquids and gases at room temperature. Scientists has discovered about four million compounds formed from two or more of 115 elements. We are amongst the best service providers of the world.
Modern chemistry evolved out of alchemy following the chemical revolution.

NEUTRONS: These are particles that are electrically neutral. A molecule is the smallest particle of an element or a compound and has all the properties of that element or compound. On the basis of physical and chemical properties, elements can be classified into two main groups: metals and non- metals. For example: All sugars are made up of three kinds of elements. Each compound of sugar form when a certain number of carbon, hydrogen and oxygen atoms join in a certain way. Our team of tutors is ready to assist and help you.ELECTRONS: Electrons are extremely light particles. ELEMENTS: A substance made of just one kind of atom is known as element. The term chemistry came from alchemy that came following Arabic word Al-kimia.We learn about the composition, structure, properties and change of matter through physical science.Chemistry also deals with topics such as intermolecular forces an general properties.For example, our chemistry assignment writers explain the interactions of substances through intermolecular forces that give matter its general properties also comes in the chemistry.The general name given to a row (left-to-right) in the periodic table (Period) 12. The state of matter represented by (aq) (Aqueous) 18. Our assignment help experts explain Chemistry as a part of physical science.
