Answer Key Ionic, Molecular, or an Acid (Honors Chemistry) Write which type of compound it is, whether the compound is ionic, molecular, or an acid. ... Identify the compunds as ionic or covalent , Then formula - Iron (II) sulfate. Thus Calcium gives its two valence electrons to Oxygen and an ionic bond is formed between them. When calcium has reacted with another element to form a calcium compound the compound is an ionic bond. Question 1. Identify the compound as ionic or covalent ( name it ) Barium chlorate. (a) How many atoms of each kind are present in the following molecules: calcium oxide, chlorine, water, carbon tetrachloride? If there is a multi-valent metal present, write both the stock and classical name. Calcium Oxide is a (an) _____ compound and the formula for Calcium Oxide is _____. From a list of almost 2000 names and formulas, students will be given the opportunity to practice their ability to name ionic compounds, given the formula, and determine the formula given the name. Formula Type Chemical Name CaO I Calcium oxide C 2 H 2 M Dicarbon dihydride LiOH I Lithium hydroxide SO 3 M Sulfur trioxide (1) Water ; (2) Calcium oxide Answer: (1)Water → covalent bond. Ionic Because the bond forms between a metal (Ca) and a non-metal (O), the bond will most likely be ionic. Ionic. For example, calcium carbonate (CaCO3), calcium oxide (CaO), calcium hydroxide (Ca(OH)2), etc. Ionic Ba(CI) Using the periodic table, predict whether the following chlorides are ionic or covalent: SiCl4, PCl3, CaCl2, CsCl, CuCl2, and CrCl3. Ca or calcium is an atom which form positive ions. Draw an electron dot diagram to show the formation of each of the following compounds – (1) Methane (2) Magnesium chloride [H = 1, C = 6, Mg = 12, Cl = 17] Answer: Additional Questions. Ionic bonds are for metal + non-metal compounds. (b) How many electrons are required by each atom mentioned in (a) to attain the nearest noble gas configuration? If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. (2) Calcium oxide → ionic bond or electrovalent bond. ionic, CaO. Ionic FeS. OH obtain one electron to be stable. reason: OH or hydroxide is a radical which form negative ions. Atoms are neither created nor destroyed during a chemical change; they are rearranged. Hence Calcium Oxide is an ionic or electrovalent compound. Calcium carbonate (CaCO3), essentially, is an ionic compound having the bivalent calcium and carbonate ions. 2 OH radicals obtain the 2 electrons released by Ca Ca give out 2 electrons to be stable. Chlorine, Cl 2 – 2 chlorine atoms If a bond forms between two non-metals, then the bond is most likely covalent. One magnet's south pole and the other magnet's north pole are attracted. But the carbonate anion is a polyatomic species. Question 4. Beryllium Oxide ( BeO ) is Ionic I'll tell you the ionic or Covalent bond list below. 7. Ionic compounds can be compared to two magnets that stick together. An electrovalent compound is formed when one atom transfers one or more electrons from itself to its neighboring atom, and an ionic bond is formed between the two atoms of the compound. When 100 grams of solid calcium carbonate is heated, 44 grams of carbon dioxide and 56 grams of calcium oxide are produced. Solution: (a) Calcium oxide, CaO – 1 calcium atom + 1 oxygen atom. Other examples of ionic compounds are, sodium oxide, copper(II) hydroxide, magnesium carbonate, etc.
