    What makes one atom different from another?

    • The number of protons it has

    • Its shape

    • Its color

    Correct Answer
    A. The number of protons it has
    Explanation
    The number of protons in an atom determines its atomic number and therefore its identity as a specific element. Each element has a unique number of protons in its nucleus, which distinguishes it from other elements. The number of protons determines the chemical properties and behavior of an atom, including its ability to form bonds and interact with other atoms. Therefore, the number of protons is what makes one atom different from another.

    Atoms are made of all of the following except

    • Protons

    • Photons

    • Electrons

    • Neutrons

    Correct Answer
    A. Photons
    Explanation
    Atoms are made up of protons, neutrons, and electrons. Protons are positively charged particles found in the nucleus of an atom, neutrons are neutral particles also found in the nucleus, and electrons are negatively charged particles that orbit around the nucleus. Photons, on the other hand, are particles of light and do not make up the structure of an atom. Therefore, photons are not a component of atoms.

    The ___________ table is a list of elements and their properties.

    • Element\

    • Atomic

    • Periodic

    Correct Answer
    A. Periodic
    Explanation
    The periodic table is a list of elements and their properties. It organizes the elements based on their atomic number, electron configuration, and recurring chemical properties. It provides valuable information about each element, such as its symbol, atomic mass, and atomic number. By using the periodic table, scientists can easily identify and compare the properties of different elements, which is crucial for understanding and predicting their behavior in chemical reactions.

     A substance made up of atoms that all possess the same number of protons are called:

    • Minerals

    • Elements

    • Compounds

    Correct Answer
    A. Elements
    Explanation
    Elements are substances made up of atoms that all possess the same number of protons. Each element is unique and is defined by its atomic number, which corresponds to the number of protons in its nucleus. Elements cannot be broken down into simpler substances by chemical reactions and are the building blocks of all matter. Minerals and compounds, on the other hand, are composed of different elements combined in specific ways.
