How many valence (outer-shell) electrons does each of the following atoms have? (a) Oxygen (b) Magnesium (c) Fluorine Valence Electrons: Valence electrons are the outermost electrons of an element or an ion. These are the electrons that are most ...
Answer to: How many valence electrons does S have? Periodic Element S Atoms have several layers, with the nucleus at the center and electrons surrounding it. Electrons on the outermost layer, or shell, of the atom, are called valence electrons. How many they have and how they are arranged...

How many electrons does cobalt have? Cobalt Cobalt is a transition metal that is located in the first row of the transition metals. Its atomic mass is 58.933 g/mole and is used to make blue pigments. The largest mining operations for cobalt are in Central Africa. ...
Valency isthe combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell. Is carbon a trivalent? The number of bonds that a neutral atom forms is called its val...
According to William Raiford, technology manager with DuPont Fluoroproducts, fluorine's electron structure is very stable -- it doesn't share its electrons with other atoms easily. The chemical composition of PTFE is based on two carbon atoms and four fluorine atoms, which are repeated through...
In chemistry, a compound's valence number is the number of bonds formed by the electrons in the last (outer) shell (called valence electrons) of atoms to other atoms' valence electrons. The octet rule (the tendency of an atom to seek stability by filling its outer shell with eight electro...
Each electron orbit of the same size or energy (shell) could only hold so many electrons. For example, the first shell could hold two electrons, the second could hold eight electrons, the third could hold 18 electrons, the fourth 32 and so on until reaching the seventh. ...
There are two electrons in the inner shell, and eight in the middle shell. That’s fine, but there’sonly sevenin the outer shell. That shell can take up to 18 electrons. But only seven means this atom isANGRY. This atom is not going to beIGNORED. ...
How many electrons does aluminium have? What are the properties of transition metals? What is an element in the third period (row) of the periodic table with four 3p electrons? While balancing a chemical equation, how can one decide which elements to balance...
