Bohr and the Periodic table :: essays research papers

Bohrs Model at that place atomic number 18 three main leaves of an atom the electrons, protons and the neutrons. Each part has go against. It is rather positive, negative, or neutral. An electron everlastingly has a negative charge. Protons always have negative charges. Then finally the neutron is a neutral charge or a charge of goose egg. If the charge of the whole atom it zero that pisseds there atomic number 18 an equal number of positive and negative pieces. An electron can be found anywhere around the nucleus, and the protons and neutrons are in the nucleus. You can not pin point were the electrons are just now the area that it can be in is called a shell.Periodic display boardOn the periodic table the horizontal rows are called periods, and the Vertical columns are called groups. Elements that are in the same row have something in common. Elements in the same period have the same number of atomic shells. every element in the top row has one shell for its electrons. The flash row has two shells for their electrons. Now, the most shells for one element is seven. Less limited groups are called families. Families are grouped by their chemical properties and how the elements react with the international world. The columns in the periodic table are mostly used to list families. A family of elements can be found in many diverse ways. An isotope is an atom that is missing or that has an unembellished neutron. Ionic BondsIons are atoms with an extra electron or a missing electron. But a frequent atom would be neutral because it has the same number of electrons as the atomic number. If you are an atom and you are missing one electron, it does not mean that you are another atom, but you are not a flesh out atom either. You are something new, an ion. The goal of an atom is to be happy. If you have modify shells you are called stable. When you give up the extra electron you are gentle and other atoms want to bond with you. The two main types of bonding are covaent and electrovalent. Ionic bonds are really groups of charged ions held together by galvanizing forces.Covailent BondsCovailent compounds happen when the electrons are shared by the atoms.
