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.
All you have to remember most importantly, is that Ionic is metal + non-metal For examples, in KCl, Potassium is an alkali metal and Chloride is a hallide (non-metal) In SiCl4, Silicon and Chlorine are both non-metals so form a covalent bond (and atoms that form this bond are termed molecules).ut there are also complex ions such as NH4+ and SO42- which form ionic bonds despite containing non metals. So best way is to remember the valency or charge of each simple or complex ion. A compound consisting of a cation(+ ve charge) and an anion(-ve charge) will be instantly recognized as ionic.
