Valence Electrons and the Periodic Table


It is well known to us that an atom consists of protons, neutrons, and electrons. The central mass of an atom is made up of protons and neutrons and electrons revolve in orbitals. The number and arrangement of protons, neutrons and electrons in an atom determine the physical, chemical and electrical properties of an element. The numbers and arrangements of protons, neutrons and electrons in an atom are collectively called structure of an atom of the element. The structure is alternatively called atomic structure. The atomic structure of carbon and copper are not same and this is the reason the properties of carbon and copper are different.

Comprehensive data on the chemical element Copper is provided on this page; including scores of properties, element names in many languages, most known nuclides of Copper. Common chemical compounds are also provided for many elements. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies. A list of reference sources used to compile the data provided on our periodic table of elements can be found on the main periodic table page. Kenneth Barbalace.

As was pointed out in the introduction to this section, electronics are the use of the electrical charge to serve some function. That electrical charge is created at an atomic level through creation of positively and negatively charged ions. In a neutrally charged atom, having neither a positive nor a negative charge, there are an equal number of protons and electrons. In a negatively charged ion there are more electrons than protons. In a positively charged ion there are fewer electrons than protons.

Electrical conduction is caused by electrons breaking free of their atoms and moving around. Atoms of some elements let go of their outer electrons pretty easily, which makes these elements good conductors. In other elements, the atoms hold on to their electrons, so these elements don't conduct electricity as well. Copper and silicon are used here as examples. The same general ideas apply to other elements. The atomic number of copper is 29, which means it has 29 protons in the middle and 29 electrons moving around the outside. The 29 negative charges of the electrons and the 29 positive charges of the protons balance out, so the atom is neutral when all of its electrons are in place.

Valence of the elements

In chemistry , a valence electron is an outer shell electron that is associated with an atom , and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond , both atoms in the bond contribute one valence electron in order to form a shared pair. The presence of valence electrons can determine the element 's chemical properties, such as its valence —whether it may bond with other elements and, if so, how readily and with how many. - By using our site, you acknowledge that you have read and understand our Cookie Policy , Privacy Policy , and our Terms of Service.

  1. The easiest way to get the valence number of electrons is to first find out where it falls in the periodic table. If it is a non-transitional element.
