Questions and Answers
  • 1. 

    Protons...

    • A.

      Are negatively charged

    • B.

      Orbit the nucleus

    • C.

      Are positively charged

    • D.

      1/2000 amu

    Correct Answer
    C. Are positively charged
    Explanation
    Protons are positively charged particles found in the nucleus of an atom. They have a charge of +1 and a mass of approximately 1 atomic mass unit (amu). This is in contrast to electrons, which are negatively charged and orbit the nucleus. The statement "are positively charged" accurately describes the nature of protons.

    Rate this question:

  • 2. 

    Electrons...

    • A.

      Orbit the nucleus and negatively charged

    • B.

      Are positively charged and make up the nucleus

    • C.

      Take up most of the mass in the atom

    • D.

      Are the same as the atomic number

    Correct Answer
    A. Orbit the nucleus and negatively charged
    Explanation
    Electrons orbit the nucleus and are negatively charged. This is a basic concept in atomic structure. Electrons are subatomic particles that are found outside the nucleus and they have a negative charge. They play a crucial role in determining the chemical and physical properties of an atom.

    • A.

      Is made up of protons and neutrons

    • B.

      Orbits the center proton

    • C.

      Is the coldest point in the atom

    • D.

      Surrounds the atom

    Correct Answer
    A. Is made up of protons and neutrons
    Explanation
    The nucleus makes up most of the mass and is made up of protons and neutrons.

    Rate this question:

  • 4. 

    The atomic number

    • A.

      Tells what can and what cannot move in an atom

    • B.

      Orbits the center proton

    • C.

      States how many spoolas are in the nucleus

    • D.

      Is the same as the amount of protons

    Correct Answer
    D. Is the same as the amount of protons
    Explanation
    The atomic number of an atom refers to the number of protons present in its nucleus. Since protons have a positive charge, they determine the element's identity and play a crucial role in the atom's overall behavior. The number of protons also determines the number of electrons in a neutral atom, as the two must balance each other out. Therefore, the atomic number being the same as the amount of protons is a correct statement.

    AMU stands for 

    • A.

      Absolute Mass Unit

    • B.

      Atomic Making Unit

    • C.

      Atomic Mass Unit

    • D.

      Abraham's Mass Unit

    Correct Answer
    C. Atomic Mass Unit
    Explanation
    AMU stands for Atomic Mass Unit. This unit is used to measure the mass of atoms and molecules. It is defined as one-twelfth the mass of a carbon-12 atom. The atomic mass unit is commonly used in chemistry and physics to express the relative masses of atoms and molecules.

    If the atomic number is 9, the number of protons is

    • A.

      8

    • B.

      9

    • C.

      1

    • D.

      12

    Correct Answer
    B. 9
    Explanation
    The atomic number of an element represents the number of protons in its nucleus. Since the atomic number given is 9, it means that the element has 9 protons. Therefore, the correct answer is 9.

  • 7. 

    If Uranium's atomic number is is 92 and it has 10 neutrons, how many protons does it have?

    • A.

      92

    • B.

      86

    • C.

      82

    • D.

      102

    Correct Answer
    A. 92
    Explanation
    Uranium's atomic number represents the number of protons in its nucleus. Therefore, if Uranium's atomic number is 92, it means that it has 92 protons. The number of neutrons is not relevant to determining the number of protons.

  • 8. 

    If Aluminum has an atomic number of 13 and has 14 neutrons, what is its mass?

    • A.

      25

    • B.

      1

    • C.

      32

    • D.

      27

    Correct Answer
    D. 27
    Explanation
    Aluminum has an atomic number of 13, which represents the number of protons in its nucleus. The mass number of an element is the sum of protons and neutrons in its nucleus. Since it is mentioned that Aluminum has 14 neutrons, we can calculate its mass by adding the number of protons (13) and neutrons (14), which equals 27. Therefore, the correct answer is 27.

    An ion forms when an atom gains or losses.

    • A.

      Protons.

    • B.

      Neutrons.

    • C.

      Electrons.

    • D.

      Quarks.

    Correct Answer
    C. Electrons.
    Explanation
    An ion forms when an atom gains or loses electrons. Electrons are negatively charged particles that orbit the nucleus of an atom. When an atom gains or loses electrons, it becomes electrically charged and forms an ion. Gaining electrons results in a negative ion (anion), while losing electrons leads to a positive ion (cation). The number of protons and neutrons in an atom does not change when an ion forms, only the number of electrons. Quarks, on the other hand, are elementary particles that make up protons and neutrons, and they do not directly participate in the formation of ions.

    Two atoms that have different numbers of protons are

    • A.

      Different ions.

    • B.

      Different isotopes.

    • C.

      Different elements.

    Correct Answer
    C. Different elements.
    Explanation
    Atoms with different numbers of protons are different elements because the number of protons determines the atomic number, which is unique to each element. Elements are defined by the number of protons in their nucleus, so if two atoms have different numbers of protons, they belong to different elements. Ions are atoms or molecules that have gained or lost electrons, and isotopes are atoms of the same element with different numbers of neutrons. Therefore, the correct answer is different elements.

    Rate this question:

  • 11. 

    Area around an atomic nucleus where an electron is most likely to be found

    • A.

      Electron cloud

    • B.

      Nucleus

    • C.

      Proton

    Correct Answer
    A. Electron cloud
    Explanation
    The electron cloud refers to the area around an atomic nucleus where an electron is most likely to be found. This region is not a fixed path or orbit, but rather a probability distribution of where the electron is likely to exist. The electron cloud is a fundamental concept in quantum mechanics and helps to describe the behavior and properties of electrons in atoms. It is important to note that the electron cloud is not a physical structure, but rather a mathematical representation of the electron's position.

    1. Which of the following elements in the chart is a cation (positive charge)? ________
    2. Which of the following elements in the chart is anion (negative charge)? pick one ________
    3. Which of the following elements in the chart is a stable atom? ________
    Calcium (Ca) Beryllium (Be) Fluorine (F) Neon (Ne) Protons 20 4 9 10 Neutrons 21 5 9 10 Electrons 20 5 10 9

    Correct Answer
    Neon,Ne
    Beryllium,Be,Flourine,F
    Calcium,Ca
    Explanation
    The element with a positive charge (cation) is Calcium (Ca) because it has 20 protons and 20 electrons, resulting in a net positive charge. The element with a negative charge (anion) is Fluorine (F) because it has 9 protons and 10 electrons, resulting in a net negative charge. The stable atom is Neon (Ne) because it has 10 protons and 10 electrons, resulting in a balanced charge. Beryllium (Be) does not have a charge specified, so it cannot be determined if it is a cation, anion, or stable atom.

      4. How many protons________ and neutrons________ are in the third isotope?  

    Correct Answer
    Carbon,C
    mass number,mass
    6,six
    6,six
    6,six
    7,seven
    6,six
    8,eight
    Explanation
    The element is Carbon (C) because the atomic number is 6, which corresponds to the number of protons in the nucleus of the atom. The numbers 12, 13, and 14 refer to the mass numbers of the isotopes. The first isotope, C-12, has 6 protons and 6 neutrons. The second isotope, C-13, has 6 protons and 7 neutrons. The third isotope, C-14, has 6 protons and 8 neutrons.
