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 >
Gallium has three valence electrons. One can find this by looking at the electron configuration, which is Ga:[Ar] 4s2 3d10 4p1. In a chemical reaction, one can lose the electrons in the 4s and 4p subshell, and the total number of electrons in these subshells is three.Full Answer >
An atom of boron has three valence electrons. The valence electrons of boron occupy the second orbit around the nucleus of the boron atom. Thus, the boron atom has an electronic configuration of [He] 2s2 2p1.Full Answer >
