sulfur (S)
beryllium (Be)
potassium (K)
silicon (Si)
what is the correct answer
The correct answer is silicon (Si). Silicon has four valence electrons. It is located in group 14 of the periodic table, which is also known as the carbon group, and elements in this group typically have four valence electrons.
To determine which element has four valence electrons, we need to identify the element's group number on the periodic table. Valence electrons are the electrons present in the outermost shell of an atom. The group number indicates the number of valence electrons an element possesses.
Silicon (Si) is located in Group 14 of the periodic table, and it has four valence electrons.
Sulfur (S) is located in Group 16 of the periodic table, and it has six valence electrons.
Beryllium (Be) is located in Group 2 of the periodic table, and it has two valence electrons.
Potassium (K) is located in Group 1 of the periodic table, and it has one valence electron.
Therefore, the element with four valence electrons is silicon (Si).
