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.
Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals) An io â¦ nic compound is a pure substance that is formed from a metal and a nonmetal.here are two important types of covalent bonds: non-polar and polar bonds. Non-polar covalent bonds are incredibly rare, and only formed when there is a minute difference in the electronegativity of two atoms. Most commonly, they form between two atoms of the same type, which have no difference in electronegativity.
