  • 2. 

    The atomic particles that are positively charged are?

    • Protons

    • Electrons

    • Neutrons

    Correct Answer
    A. Protons
    Explanation
    Protons are atomic particles that carry a positive charge. They are found in the nucleus of an atom and are equal in number to the number of electrons in a neutral atom. Electrons, on the other hand, are negatively charged and orbit around the nucleus. Neutrons have no charge and are also found in the nucleus. Therefore, the correct answer is protons.

    The atomic particles that have no charge are?

    • Electrons

    • Protons

    • Neutrons

    Correct Answer
    A. Neutrons
    Explanation
    Neutrons are atomic particles that have no charge. Unlike electrons, which carry a negative charge, and protons, which carry a positive charge, neutrons are electrically neutral. They are found in the nucleus of an atom along with protons, and their main role is to contribute to the mass of the atom without affecting its overall charge.

    Which particles are located on shells orbiting the nucleus of atoms?

    • Electrons

    • Protons

    • Neutrons

    Correct Answer
    A. Electrons
    Explanation
    Electrons are located on shells orbiting the nucleus of atoms. Protons and neutrons, on the other hand, are located within the nucleus itself. Electrons are negatively charged particles that occupy specific energy levels or shells around the nucleus. These shells determine the electron's distance from the nucleus and play a crucial role in chemical bonding and the overall stability of the atom.

    The atomic particles that are negatively charged are?

    • Neutrons

    • Protons

    • Electrons

    Correct Answer
    A. Electrons
    Explanation
    Electrons are the atomic particles that are negatively charged. They orbit around the nucleus of an atom and carry a negative electrical charge. Neutrons, on the other hand, have no charge, while protons carry a positive charge. Therefore, electrons are the correct answer in this case.

    Which atoms has 12 electrons?

    • Carbon

    • Lithium

    • Magnesium

    • Oxygen

    Correct Answer
    A. Magnesium
    Explanation
    Magnesium has 12 electrons because it is located in Group 2 of the periodic table, which means it has 2 valence electrons and 10 core electrons. The atomic number of magnesium is 12, indicating that it has 12 protons and therefore 12 electrons in a neutral atom.

    How many electrons does Sodium have?  

    • 12

    • 23

    • 11

    • 44

    Correct Answer
    A. 11
    Explanation
    Sodium has 11 electrons. This is because the atomic number of sodium is 11, which represents the number of protons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, so sodium also has 11 electrons.

    Rate this question:

  • 8. 

    Potassium has and electronic configuration of?

    • 2, 8,1

    • 2, 8, 7

    • 2, 8, 8, 1

    • 2, 8, 5

    Correct Answer
    A. 2, 8, 8, 1
    Explanation
    The correct answer is 2, 8, 8, 1. This is because the atomic number of potassium is 19, which means it has 19 electrons. The electronic configuration represents the distribution of these electrons in different energy levels or shells. The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, and the third energy level can hold up to 8 electrons as well. Therefore, the electronic configuration of potassium is 2, 8, 8, 1.

    Rate this question:

  • 9. 

    Which atom has an electronic configuration of  2, 5?

    • Boron

    • Lithium

    • Carbon

    • Nitrogen

    Correct Answer
    A. Nitrogen
    Explanation
    Nitrogen is the correct answer because it has an atomic number of 7, which means it has 7 electrons. The electronic configuration of 2, 5 indicates that there are 2 electrons in the first energy level and 5 electrons in the second energy level, which matches the electronic configuration of nitrogen.

    Rate this question:

  • 10. 

    How many Neutrons does Sodium have?  

    • 23

    • 12

    • 11

    • 44

    Correct Answer
    A. 12
