Lab3_Ionic and Covalent Compounds Prelab Complete .very correct
Prelab Activity: Ionic Compounds 1 point for each complete table, 5 points total. This exercise is due at the start of lab. Ionic compounds are hard, brittle and crystalline in nature. Ionic compounds have high melting points compared to covalent compounds. Many ionic compounds are water soluble and conduct electricity. It is possible to identify a compound as an ionic compound or a covalent compound by observing properties such as melting point, solubility and ability to conduct electricity. These properties are due to the nature of the ionic bond. Ionic bonds are made between oppositely charged ions, a cation and an anion. The cation may be a positively charged polyatomic ion or a metal ion. The anion may be a negatively charged polyatomic ion or a nonmetal ion. In this activity, you will learn about naming ionic compounds and deriving their chemical formulas. Cations and their names Metals form cations by donating electrons in their valence shell to satisfy the octet rule. The name of a cation is the same as the name of the element. Complete Table 1 by providing names of cations, their chemical symbols and charges. Table 1: Number Name of Element Chemical symbol of the element Name of the cation Chemical symbol and charge of the cation
