Answer:

Valence electrons

Explanation:

Valence electron is the number of electrons in the outermost shell of an atom. Valance electrons are equal to the group number of the elements in the periodic table. For example, halogens are located in group 7 of the periodic table, and they have 7 valence electrons. Also alkali metals located in group 1 have 1 valence electron. In the formation of an ionic bond valence electrons are either lost or gained, and in covalent bonds valence electrons are shared.

Which half reaction can occur at the anode in a voltaic cell
luda_lava [24]

Oxidation is the half reaction that can occur at the anode in a voltaic cell.

Explanation:

In electrodes which is metal strip in voltaic cell the reactions occurs. The two electrodes placed one in each half-cell. The reduction reaction occurs at cathode and oxidation occurs at anode.

A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Half-reactions are often used as a method of balancing redox reactions.

In an oxidation half reaction, an atom loses electron(s). When an element is oxidized it loses a specific number of electrons.
