The reason Catholics do not eat meat on Fridays is in remembrance  of the day of Jesus Christ's sacrifice for all of humanity. It is a  form of penance to honor and worship â¦ God.    Note that many Catholics today believe that the Church allows them  to eat meat on Fridays except during Lent. This is not true.
Some compounds contain both ionic and covalent bonds. These compounds contain polyatomic ions. Many of these compounds contain a metal, a nonmetal and also hydrogen. However, other examples contain a metal joined via an ionic bond to covalently bonded nonmetals. Here are examples of compounds that exhibit both types of chemical bonding. Examples of Ionic Bonds-Ionic Compounds. Examples of Covalent Bonds-Covalent Compounds.
A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a me â¦ tal and a non metal due to the attraction between oppositely charged ions. A Covalent (or molecular) bond is a bond between two non-metallic elements. This means that they share electrons inside the molecules. OR A type of chemical bond in which there is mutual sharing of electrons between two atoms is called covalent bond.
