Covalent compounds are always poor conductors of electricity while ionic compounds conduct electricity well when melted or dissolved.
Covalent compounds can be solid, liquid or gas, but ionic compounds are solids.
In covalent compounds the elements present are usually close together on the periodic table whereas in ionic compounds they are usually well separated.
<h3><u>Explanation;</u></h3>
<u>Ionic compounds are compounds that are formed from strong electrostatic interactions between ions.</u> Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. The atoms involved in ionic bonding lose or gain electrons and form positively or negatively charged ions.
<em><u>Ionic compound are good conductors of electricity both in molten and aqueous form,. while covalent compound are poor conductors of electricity.</u></em>
<u>Covalent compounds on the other hand are compounds that have bonds where electrons are shared between atoms.</u> These types bonds mostly occur between nonmetals or between two atoms of the same element.
photoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it.
The Eº cell is an intensive property, i.e they do not depend on the quantity of material present and the desired reaction in our problem is exactly half the reverse of the one given, the Eºcell will then be the negative of the first then Eºcell is -1.78 V and the redox reaction will be non-spontaneous as opposed to the first.
