0 What is ATOM?

Atom is the smallest structural unit of which the properties of elements . For example, we start to divide a piece of iron at first, we divide into two parts again, the remaining part of the board . Then we have continued to divide the parts we'd always be a piece of wood , until the small pieces that make up the atoms until the board . Some of the properties of the small parts which made ​​up of more than one atom . In this way more than one atom in the molecule formed by the small pieces are called . For example, the water molecule constituting the smallest parts . Two hydrogen atoms and an oxygen atom of a water molecule is a molecule formed by the merger . Actually atom was formed with the other parts . These parts are the proton , neutron and electron. In these parts with the smallest electron. According to the difference in the number of these parts is the difference between the atoms . For example, 10 neutrons and 15 protons , electrons in an atom having 15 to 12 neutrons and 15 protons and 15 atomic electrons of a dissimilarity. They atomlarıdırlar other substances , and the names of any other variable. There are different characteristics of these particles in the atom different from each other . Protons are positive (+ ) is installed , the electrons are negative (- ) is installed , the load shall be considered as neutrons . Are found in the nucleus of an atom the electrons , protons and neutrons , and electrons around the atoms around their own axis as well as around the nucleus of an atom ( nucleus from a particular orbit ) return.
