PERIODIC TABLE AND PROPERTIES(QUIZ-3) 1 / 5 What element does the symbol Fe stand for? Francium Fluorine Iodine Iron The symbol Fe stands for the element iron. Iron is a metallic chemical element with a silver-gray appearance and is the most common element on Earth by mass. It is essential for many biological processes in living organisms, including oxygen transport in blood (as part of hemoglobin) and as a component of various enzymes involved in metabolism. Iron is also widely used in construction and manufacturing due to its strength and ability to be easily shaped into various forms. Its magnetic properties make it useful in electrical devices and industrial applications. 2 / 5 What is the symbol for phosphorus? Po P Pb Pu The symbol "P" represents the element phosphorus in the periodic table. Chemical symbols are standardized abbreviations used to uniquely identify elements. In the case of phosphorus, the symbol "P" is derived from its name. Using symbols makes it easy to write chemical formulas and represent elements in a concise and standardized manner. Therefore, when you see the symbol P, you can specifically identify it as the element phosphorus, which has distinct properties and characteristics. 3 / 5 What is the symbol for manganese? Mo Mg Mt Mn The symbol Mn represents the element manganese in the periodic table. Chemical symbols are standardized abbreviations used to uniquely identify elements. In the case of manganese, the symbol Mn is derived from its name. The use of symbols makes it convenient to write chemical formulas and represent elements in a concise and standardized manner. Therefore, when you see the symbol Mn, you can specifically identify it as the element manganese, which has distinct properties and characteristics. 4 / 5 What is the symbol for ruthenium? Rn Ru Rh Rf The symbol "Ru" represents the element ruthenium in the periodic table. Chemical symbols are standardized abbreviations used to uniquely identify elements. In the case of ruthenium, the symbol "Ru" is derived from its name. The use of symbols makes it convenient to write chemical formulas and represent elements in a concise and standardized manner. Therefore, when you see the symbol Ru, you can specifically identify it as the element ruthenium, which has distinct properties and characteristics. 5 / 5 What is the atomic number for cesium? 20 48 6 55 The atomic number of an element is the number of protons in its nucleus. Cesium has an atomic number of 55, meaning each cesium atom has 55 protons. This positions cesium in group 1 of the periodic table, among the alkali metals. Cesium is highly reactive, especially with water, and has one of the lowest melting points of all metallic elements. It is used in various applications, such as atomic clocks and in the oil industry for drilling fluids. Knowing the atomic number helps identify elements and understand their properties and how they behave chemically. Your score isThe average score is 0% 0% Restart quiz
