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.
It has to do with the elements that make them up: ionic compounds are made of metals and nonmetals, and molecular (or covalent) compounds are made of nonmetals. We'll learn how they bond differently: in covalent compounds, the atoms share electrons, and in ion compounds, atoms steal electrons and then opposite charges attract. Ionic and molecular (covalent) compounds also look different at the microscopic level: covalent and molecular compounds exist in molecules, while ionic compounds are organized in lattice structures.
