Sulfur has six valence electrons, meaning that each atom of this element has six electrons in its outermost shell. The number of valence electrons that each element has can be predicted based on its location on the periodic table, though this only applies to neutral atoms. An element's main group number indicates how many valence electrons each atom of that element will have, and because sulfur is part of group six on the periodic table, this indicates that this element has six electrons in its outermost electron "shell."Know More
Like sulfur, oxygen is an element that has six valence electrons. This can be easily predicted by noticing that oxygen shows up under group six in the periodic table. Other elements that share this characteristic include selenium and tellurium. This rule only applies to neutral, or uncharged, atoms.
When atoms are charged, the number of electrons in its outermost energy level, or shell, will change based on the amount of charge. For example, if sulfur is charged to S-2, this means that sulfur now has eight, or two in addition to its usual six, valence electrons.
Knowing the number of an element's valence electrons can be helpful in knowing how it will bond with other atoms. In some cases, the term "valence electrons" may be abbreviated as VE.Learn more about Atoms & Molecules
The valence electrons, the outermost shell of electrons, are the largest determinant of how an atom reacts chemically to other substances in its environment. The number and arrangement of the outermost electron shell are important, as is the placement of the shell itself, since different shells hold different numbers of electrons.Full Answer >
Like all alkaline earth metals, magnesium has two valence electrons, meaning there are two electrons in its outer shell. The valence electrons are the ones that an atom shares, gains or loses when interacting with additional atoms.Full Answer >
Iron, or Fe, has 26 electrons, with two electrons in the outer valence shell. Iron is a transition metal and is both lustrous and easy to work with. Iron is also prone to rust, especially in damp environments.Full Answer >
