2/26/2019 Ch 4 HW 6/23 Metals, metalloids, and nonmetals have unique properties or characteristics that help to distinguish them. For instance, metals and metalloids tend to be shiny solids, whereas nonmetals tend to be dull solids and/or gases. See Section 4.2 ( Page 106 ) . ANSWER: Correct Elements, Their Properties, and The Periodic Table There are more than 100 chemical elements that are identified in nature. The chemical symbols of the elements are denoted by either one or two letters. For example, the element oxygen is denoted by the letter . If the symbol has two letters, the first letter is always capitalized and the second is lowercase. For example, the symbol for the element helium is . The periodic table is the tabular arrangement of all the chemical elements that have been identified. The elements are arranged according to their atomic numbers and denoted by their symbols. This arrangement places elements of similar properties next to each other in the table. For example, metals are located on the left- hand side and nonmetals are located on the right-hand side. Semimetals (metalloids) are placed between the metals and nonmetals, and have properties intermediate between metals and nonmetals. Part A Identify the chemical symbols corresponding to each element. Drag the appropriate labels to their respective targets. Hint 1. What a chemical symbol is A chemical symbol is shorthand for the name of an element. It uniquely identifies the element. The chemical symbol may be either one or two letters. If the symbol is two letters, the first letter is capitalized and the second is lowercased. For example, the chemical symbol for sulfur is , and the symbol for silicon is . In some cases, the chemical symbol is derived from the Latin or Greek name of the element. For example, the symbol of gold, , is derived from its Latin name, aurum , meaning “shining dawn.” Hint 2. Identify the Latin name of the elements Sometimes the chemical symbol of an element is derived from the Latin or Greek name for that element. Complete the following statements to identify the Latin names of the elements. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. ANSWER: ANSWER: halogen metal nonmetal metalloid Reset Help 1. The Latin name for lead is plumbum . 2. The Latin name for antimony is stibium . 3. The Latin name for sodium is natrium .
2/26/2019 Ch 4 HW 7/23 Correct Once you know the symbols for the elements, it is easier to navigate the periodic table and write chemical equations and formulae. Each element has
