Q: Answer the following question given this paragraph: Neutrons consist of fundamental particles known as quarks and gluons. Gluons carry the strong nuclear force that binds together the quarks in a neutron. Q: The two main fundamental particles that make up neutrons are quarks and what else? Choices: - prions - leptons - atoms - gluons A:
A: gluons

Q: Answer the following question given this paragraph: Ionic bonds form only between metals and nonmetals. Metals "want" to give up electrons, and nonmetals "want" to gain electrons. Find sodium (Na) in Figure below . Sodium is an alkali metal in group 1. Like other group 1 elements, it has just one valence electron. If sodium loses that one electron, it will have a full outer energy level. Now find fluorine (F) in Figure below . Fluorine is a halogen in group 17. It has seven valence electrons. If fluorine gains one electron, it will have a full outer energy level. After sodium gives up its valence electron to fluorine, both atoms have a more stable arrangement of electrons. Q: What type of bonds form only between metals and nonmetals? Choices: - non-harmonic bonds - harmonic bonds - magnetic bonds - ionic bonds A:
A: ionic bonds

Q: Answer the following question given this paragraph: Magnetism is the ability to be attracted by a magnet and to act as a magnet. Only ferromagnetic materials have this property. They include iron, cobalt, and nickel. When these materials are magnetized, they become temporary or permanent magnets. Magnetite is a natural permanent magnet. Q: What is the ability to be attracted by a magnet and to act as a magnet? Choices: - electrical attraction - polarization - inertia - magnetism A:
A: magnetism

Q: Answer the following question given this paragraph: When ordered by atomic number, the discrepancies within Mendeleev's table disappeared. Tellurium has an atomic number of 52, while iodine has an atomic number of 53. So even though tellurium does indeed have a greater atomic mass than iodine, it is properly placed before iodine in the periodic table. Mendeleev and Moseley are credited with being most responsible for the modern periodic law : When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties. The result is the periodic table as we know it today. Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with electrons. Elements with similar chemical properties appear at regular intervals, within the vertical columns called groups . Q: Each new horizontal row of the periodic table corresponds to the beginning of a new period because a new principal energy level is being filled with what? Choices: - protons - photons - neutrons - electrons A:
A: electrons
