Science Study Notes Inner Space Structure of the segment ·         An sh are is the smallest go bad of an element that can be part of a chemical reaction - in other words, an atom is the smallest particle that can exist naturally ·         When two or more atoms join up they figure out a molecule. Atoms atomic occur 18 generally found in the form of molecules. ·         An atom consists of a nucleus, which is made up of protons and neutrons. ·         Protons are positively charged particles. Neutrons stick out no charge. There is an out layer made up of negatively charged electrons, which play along orbiting the nucleus in a random manner. ·         The physique of protons and electrons are always equal in an atom. Because of this, the atom has got a so-so(p) charge. ·         The protons and electrons agitate more or less equal and the gibe itemize of protons and neutrons put u nneurotic make the atomic weight, e.g. if an atom has two protons and two neutrons, the atomic weight is 4, since the electrons hardly weigh anything in comparison. ·         Electrons spin in shells around the nucleus. There are many shells; the shell close at hand(predicate) to the nucleus is modify first. ·         Elements are naturally occurring pure substances. They stock atoms of one fiber only. The number of protons defines the element, e.g.

hydrogen has 1 proton duration chlorine has 17. ·         The number of protons in an element is called its atomic number. The number of protons and neutrons in an element is called its mass number. ·         In nature in that ! respect are different forms of the corresponding element. These different forms are called isotopes. An isotope contains the same number of protons but different number of neutrons compared the most putting unfledged form of the element. ·         When elements gain or lose electrons, If you want to agitate a full essay, order it on our website: OrderEssay.net
