    On the periodic table, cerium is found in period? - ProProfs

    On the periodic table, cerium is found in period?

    • 2

    • 3

    • 6

    • 4

    Correct Answer
    A. 6
    Explanation
    Cerium is found in period 6 on the periodic table because the period number represents the energy level or shell in which the element's valence electrons are located. Cerium has an atomic number of 58, which means it has 58 electrons. The first two electrons are in the 1s orbital, the next two are in the 2s orbital, the next six are in the 2p orbital, and so on. By the time we reach the 6th period, cerium's valence electrons are in the 6s orbital. Therefore, cerium is found in period 6 on the periodic table.

    Based on its physical and chemical properties, cerium is classified as a? - ProProfs

    Based on its physical and chemical properties, cerium is classified as a?

    • Earth metal

    • Noble metal

    • Rare-earth metal

    • Rare gas

    Correct Answer
    A. Rare-earth metal
    Explanation
    Cerium is classified as a rare-earth metal based on its physical and chemical properties. Rare-earth metals are a group of elements that are typically found in the Earth's crust and have similar characteristics. Cerium is a soft, silvery-white metal that is highly reactive and easily oxidized. It is commonly used in the production of catalytic converters, glass polishing, and as an alloying agent in metals. These properties align with the characteristics of rare-earth metals, making it the correct classification for cerium.

    What is the atomic mass of cerium? - ProProfs

    What is the atomic mass of cerium?

    • 122

    • 140

    • 188

    • 166

    Correct Answer
    A. 140
    Explanation
    The atomic mass of cerium is 140. This is the correct answer because the atomic mass of an element is the weighted average mass of all the isotopes of that element, taking into account their abundance. In the case of cerium, the most abundant isotope is cerium-140, which has a mass of 140 atomic mass units.

    An oxide of cerium is used as? - ProProfs

    An oxide of cerium is used as?

    • Drying agent

    • Antisteroid

    • Additive

    • Glass polishing agent

    Correct Answer
    A. Glass polishing agent
    Explanation
    Cerium oxide is commonly used as a glass polishing agent due to its abrasive properties. It can effectively remove scratches and imperfections from glass surfaces, leaving them smooth and shiny. The oxide particles act as a mild abrasive, gently grinding away the damaged areas without causing further damage to the glass. This makes cerium oxide an ideal choice for polishing glass objects such as lenses, mirrors, and windows.

    How does cerium react with cold water? - ProProfs

    How does cerium react with cold water?

    • Explosively

    • Violently

    • Slowly

    • Reactive

    Correct Answer
    A. Slowly
    Explanation
    Cerium reacts slowly with cold water. This means that when cerium comes into contact with cold water, it undergoes a relatively slow reaction. The reaction may not be very noticeable or vigorous, and it may take some time for the cerium to fully react with the water.
