Which element has four valence electrons?
(1 point)
* sulfur (S)
* silicon (Si)
* beryllium (Be)
* potassium (K)
Silicon (Si) has four valence electrons.
Silicon (Si) has four valence electrons.
To determine which element has four valence electrons, you need to refer to the periodic table.
The valence electrons are the electrons in the outermost shell (also known as the valence shell) of an atom. To find the number of valence electrons, you can look at the group number of the element on the periodic table.
Sulfur (S) is in group 16, silicon (Si) is in group 14, beryllium (Be) is in group 2, and potassium (K) is in group 1.
Group 16 elements have six valence electrons, so sulfur does not have four valence electrons.
Group 14 elements have four valence electrons, so silicon does have four valence electrons.
Group 2 elements have two valence electrons, so beryllium does not have four valence electrons.
Group 1 elements have one valence electron, so potassium does not have four valence electrons.
Therefore, the element with four valence electrons is silicon (Si).
