  • Question 9
    30 seconds
    Q.

    Which of the following is the term for a substance in which all the atoms have the same number of protons

    answer choices

    a compound

    An element

    a molecule

    a solid

    a gas

  • Question 10
    30 seconds
    Q.

    Which of the following reasons explains why there is a decimal for most atomic masses?

    answer choices

    The mass of one atom can have a fraction.

    Since electrons are very small mass they only add a little bit, usually only a decimals worth.

    It is the average mass of all the potential isotopes of an atom.

    Neutrons have a mass of 1.1 meaning that fractions are common.

  • Question 11
    30 seconds
    Q.

    Which of the following is true of atomic radius?

    answer choices

    The radius is mainly due to how large an atom's nucleus is.

    The radius is mainly due to the size of the electron cloud.

    The atomic radius is a way we measure the mass of an atom.

    Neutrons account for the majority of an atom's radius.
