Q:

How many valence electrons does beryllium have?

A:

Beryllium has two valence electrons. Valence electrons are those electrons that are capable of participating in the formation of chemical bonds with other atoms. These chemical bonds occur through the sharing of these two electrons with other atoms.

Valence electrons get their name from their location within an atom. These electrons are located in outermost shell of an atom, which is known as the valence shell. Because of the location, these electrons are positioned for and are capable of exchange with other atoms. Beryllium possesses an atomic number of 4. Beryllium exists in the form of a hard gray metal.

    How many valence electrons does titanium have?

    A:

    Titanium has four valence electrons. Valence electrons are generally the electrons located in the outermost shell of an atom and can be gained or lost in a reaction. Valence electrons can be determined by looking at the periodic table; because titanium is four columns from the left, it has four valence electrons.

  • Q:

    How many valence electrons does sulfur have?

    A:

    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."
