    A single proton has what type of charge?

    • Negative

    • Balanced

    • Positive

    • Neutral

    Correct Answer
    A. Positive
    Explanation
    A single proton has a positive charge because protons are subatomic particles that carry a positive electrical charge. They are found in the nucleus of an atom and are one of the two main types of particles that make up an atom, the other being neutrons. Electrons, on the other hand, carry a negative charge and orbit around the nucleus. So, in summary, a single proton has a positive charge.

    If carbon has an atomic mass of 12 and 6 neutrons, how many protons and electrons does it have, respectively?

    • 6,6

    • 6,12

    • 12,6

    • 24,6

    Correct Answer
    A. 6,6
    Explanation
    Carbon has an atomic number of 6, which indicates the number of protons in its nucleus. Since the question states that carbon has 6 protons, the correct answer is 6. Additionally, in a neutral atom, the number of protons is equal to the number of electrons. Therefore, carbon also has 6 electrons.

    Which of the following is located in the nucleus?

    • A. proton

    • B. electron

    • C. orbital

    Correct Answer
    A. A. proton
    Explanation
    Protons are positively charged subatomic particles that are found within the nucleus of an atom. The nucleus is the central region of an atom and contains most of its mass. Electrons, on the other hand, are negatively charged particles that orbit around the nucleus in specific energy levels called orbitals. Orbitals are not located in the nucleus. Therefore, the correct answer is a. proton.

    The atomic number

    • Tells what can and what cannot move in an atom

    • Orbits the center proton

    • States how many spoolas are in the nucleus

    • Is the same as the amount of protons

    Correct Answer
    A. Is the same as the amount of protons
    Explanation
    The atomic number of an atom refers to the number of protons in its nucleus. Protons are positively charged particles, and the atomic number determines the element and its properties. It also determines the number of electrons in a neutral atom, as atoms are electrically neutral and have the same number of protons and electrons. The atomic number is a fundamental characteristic of an element and is used to organize the periodic table.

    Choose the correct subatomic particles for Oxygen.  Check only the boxes that apply

    • 5 protons

    • 8 electrons

    • 3 neutrons

    • 8 protons

    • 4 electrons

    • 5 neutrons

    • 8 neutrons

    Correct Answer(s)
    A. 8 electrons
    A. 8 protons
    A. 8 neutrons
    Explanation
    The correct answer is 8 electrons, 8 protons, 8 neutrons. Oxygen has an atomic number of 8, which means it has 8 protons and 8 electrons to maintain a neutral charge. The atomic mass of oxygen is typically around 16, so it also has 8 neutrons to balance out the atomic mass.

    Correct Answer
    A. Elements
    Explanation
    Pure Gold, Pure Silver, and pure Oxygen are all elements. Elements are substances that cannot be broken down into simpler substances by chemical means. They are made up of atoms of the same type. In this case, pure Gold, pure Silver, and pure Oxygen are all composed of only one type of atom, making them elements.

    Rate this question:

    Electrons...

    • Orbit the nucleus and negatively charged

    • Are positively charged and make up the nucleus

    • Take up most of the mass in the atom

    • 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 fundamental concept in atomic structure. Electrons are subatomic particles that revolve around the nucleus in specific energy levels or orbitals. They carry a negative charge, which is equal in magnitude to the positive charge of the protons in the nucleus. The arrangement of electrons in these orbitals determines the chemical properties and reactivity of an atom.

    An atom is the smallest particle you can get. There is nothing smaller than an atom.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement is true because an atom is indeed the smallest particle that exists. Atoms are made up of protons, neutrons, and electrons, and they cannot be divided further without losing their chemical properties. Subatomic particles such as quarks and leptons exist within atoms, but they are not considered as separate particles on their own. Therefore, an atom is the fundamental building block of matter and cannot be broken down into anything smaller.

    Correct Answer
    A. Period
    Explanation
    A horizontal row of the periodic table is called a period. Periods represent the energy levels or shells in which the electrons of an atom are arranged. Each period corresponds to a specific number of electron shells that an atom can have. The number of the period indicates the highest energy level occupied by electrons in that row.

    Rate this question:

  • 48. 

    If lithium has an atomic number of 3 and a mass number of 7, the correct number of protons, neutrons, and electrons, respectively, is:

    • 3,4,3

    • 4,3,3

    • 3,3,4

    • 4,4,3

    Correct Answer
    A. 3,4,3
    Explanation
    Lithium has an atomic number of 3, which indicates that it has 3 protons. The mass number of 7 suggests that it has a total of 7 nucleons, which includes both protons and neutrons. Since we know that lithium has 3 protons, subtracting this from the mass number gives us the number of neutrons. Therefore, the correct number of protons, neutrons, and electrons for lithium is 3, 4, and 3 respectively.

    Rate this question:

  • 49. 

    How many protons, neutrons and electrons are in the following atom Fluorine-19

    • P=9, E=10, N=9

    • P=9, E=9, N=10

    • P=9, E=9, N=19

    • P=19, E=19, N=19

    Correct Answer
    A. P=9, E=9, N=10
    Explanation
    The correct answer is P=9, E=9, N=10. Fluorine-19 has an atomic number of 9, which means it has 9 protons and 9 electrons. The atomic mass of Fluorine-19 is 19, so the number of neutrons can be calculated by subtracting the atomic number from the atomic mass, giving us 10 neutrons.
