![]() ![]() The shell number representing the valence shell will differ depending on the atom in question. Valence electrons are electrons found in the outermost shell of an atom. Here is a video which gives further explanation of this topic. Fluorine has the electron arrangement 2.7. The last number is how we know the number of valence electrons.Īluminium has the electron arrangement 2.8.3. So, sodium's 11 electrons are arranged this way: 2 electrons in the first "shell", 8 electrons in the second "shell" and 1 electron (the valence electron) in the third "shell". The third "shell" is a bit more complicated but let's just say that it takes up to 8 electrons as well (for now.). The second "shell" can have up to 8 electrons. Depending on your level of Chemistry, it is probably easier to think of them as particles orbiting the nucleus. Sodium has 11 electrons: its atomic number is 11, so it has 11 protons atoms are neutral, so this means sodium also has 11 electrons.Įlectrons are arranged in "shells" or energy levels. This citation format is based on MLA.Valence electrons are the outermost electrons, and are the ones involved in bonding. Also replace URL for the actual url of this page (The stay, ok?). Now replace dd, mmmm and yyyy with the day, month, and year you browsed this page. "Valence Electrons in Tantalum (Ta) [& Facts, Color, Discovery. To make your life (and citation) easier just copy & paste the information below into your assignment or essay: That gives credibility to your paper and it is sometimes required in higher education.

Maybe add your school logo, work team or anything else to maker your paper look cool?Īlong with basic atom / element information (like Tantalum valence electrons and all the other atomic data), it also comes with color coded info about: State (Gas, Liquid or Solid at room temperature), Groups/series details and much more. How a small number of atoms can be joined and form completely different substances.Video Are you having trouble understanding the basics of atomic elements? This video will walk you through: Want to learn more details and data about Tantalum (Ta)? Check my Elements Comprehensive List. ![]() ![]() SourcesChiefly occurs in the mineral tantalite. Name OriginFrom king Tantalus of Greek mythology, father of Niobe. It and its alloys are corrosion and wear resistant so it is used to make surgical and dental tools. Tantalum pentoxide is used in capacitors and in camera lenses to increase refracting power. UsesOften used as an economical substitute for platinum. In the case of Tantalum the valence electrons is 3,5. Now let's check the facts about Tantalum.ĭescriptionRare, gray, heavy, hard but ductile, metal with a high melting point. Ok but how many valence electrons does an atom of Tantalum have? A valence electron is an outer shell electron and may participate in the formation of a chemical bond. ![]()
