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 outermost shell of an iron atom contains two electrons. This number can be found from the electron configuration for iron, written as 1s2 2s2p6 3s2p6d6 4s2. The outermost shell is the fourth energy level, which contains two electrons in the s-orbital.Full Answer >
There are multiple elements that have six valence electrons, including oxygen and sulfur. These elements can be found in the sixteenth group in the vertical column of the periodic table, also known as the chalcogens.Full Answer >
Iron has two valence electrons. The atomic number or iron is 26, and it has 26 electrons and 26 protons. The electron configuration of iron is 1s22s22p63s23p63d64s2 or 2, 8, 14, 2 electrons per shell, so an atom of iron has two electrons in the outermost shell.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 >
