A carbon atom has four valence electrons. The number of valence electrons of any atom of an element can be determined by the period table group in which the element is classified. There are a total of 18 groups on the pe... More »

Phosphorous has five valence electrons. This means there are five electrons in the element's outermost shell. The number of valence electrons is determined by looking at the atomic number of the element on the periodic t... More »

The number of valence electrons in cobalt is two. This means two electrons are found in the outermost shell of a single atom of cobalt. More »

One neutral atom of carbon has four valence electrons. An easy way to tell how many valence electrons an element has is to look at the periodic table and find the element's main group number. Carbon is in group 4, which ... More »

C2H2 has a straight-line molecular geometry consisting of a hydrogen atom bonded to a carbon atom, which is triple-bonded to a second carbon atom bonded to a second hydrogen atom. The common name for this molecule is ace... More »

To find the valence electrons in an atom, identify what group the element is in. An element in group 1A has 1 valence electron. For example, Li is in group 1A, so that means it has one valence electron. If the element is... More »

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 perio... More »
