    Which element has a mass of 65?

    Correct Answer
    Zinc
    zinc
    Zink
    zink
    Explanation
    Zinc is the correct answer because it is the only element mentioned in the options that has a mass of 65. The other options, "zinc," "Zink," and "zink," are just variations in capitalization and spelling of the correct answer, but they all refer to the same element.

      Halogen

    Correct Answer
    A. Metal
    Explanation
    Potassium is a metal because it is a highly reactive alkali metal that belongs to Group 1 of the periodic table. It has a low ionization energy and readily loses its single valence electron to form a positive ion. Metals generally have lustrous appearances, conduct electricity and heat, and are malleable and ductile. Potassium exhibits these characteristics, making it a typical example of a metal.

    • E.

      100

    Correct Answer
    D. 98
    Explanation
    Californium is a chemical element with the symbol Cf and atomic number 98. The atomic number represents the number of protons in the nucleus of an atom. Therefore, Californium has 98 protons.

      97

    • D.

      98

    • E.

      99

    Correct Answer
    D. 98
    Explanation
    Californium is a chemical element with the atomic number 98, which corresponds to the number of protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons. Therefore, Californium has 98 electrons.

    Rate this question:

  • 13. 

    How many netrons does Californium have?

    • A.

      110

    • B.

      153

    • C.

      98

    • D.

      251

    • E.

      1

    Correct Answer
    B. 153
    Explanation
    Californium has 153 neutrons. Neutrons are subatomic particles that have no charge and are found in the nucleus of an atom. The number of neutrons in an atom can vary, but it is determined by subtracting the atomic number (which represents the number of protons) from the atomic mass. In the case of Californium, the atomic mass is 251 and the atomic number is 98, so subtracting 98 from 251 gives us 153 neutrons.

  • 14. 

    How many neutrons does Be have?

    • A.

      4

    • B.

      5

    • C.

      6

    • D.

      7

    • E.

      9

    Correct Answer
    B. 5
    Explanation
    Beryllium (Be) has an atomic number of 4, which indicates the number of protons in its nucleus. The atomic mass of Be is approximately 9, which is the sum of the protons and neutrons in the nucleus. Therefore, the number of neutrons in Be can be calculated by subtracting the atomic number from the atomic mass. In this case, 9 - 4 = 5, so Be has 5 neutrons.

    Rate this question:

  • 15. 

    What is the formula for calculating the number of neutrons in an element?

    • A.

      Atomic mass - atomic number

    • B.

      Atomic number - atomic mass

    • C.

      Atomic weight - atomic mass

    • D.

      Atomic mass - atomic weight

    • E.

      # of protons - # of electrons

    Correct Answer
    A. Atomic mass - atomic number
    Explanation
    The formula for calculating the number of neutrons in an element is atomic mass - atomic number. This is because the atomic mass represents the total mass of an atom, which includes both the protons and neutrons. The atomic number represents the number of protons in an atom. By subtracting the atomic number from the atomic mass, we can determine the number of neutrons present in the atom.
