Q: Answer the following question given this paragraph: Electronegativity Differences between Metals and Nonmetals An element's electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity ( 2.2 in Figure 7.15 "Pauling Electronegativity Values of the ") have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i. , they are oxidants). In contrast, elements with a low electronegativity ( 1.8) have electron affinities that have either positive or small negative values and small ionization potentials, so they are generally metals and good electrical conductors that tend to lose their valence electrons in chemical reactions (i. , they are reductants). In between the metals and nonmetals, along the heavy diagonal line running from B to At in Figure 1.24 "The Periodic Table Showing the Elements in Order of Increasing ", is a group of elements with intermediate electronegativities ( ~ 2.0). These are the semimetals, elements that have some of the chemical properties of both nonmetals and metals. The distinction between metals and nonmetals is. Q: What are metals and good electrical conductors that tend to lose their valence electrons in chemical reactions called? Choices: - stable metals - conservants - precious metals - reductants A:
A: reductants

Q: Answer the following question given this paragraph: Summary Subatomic particles of the nucleus (protons and neutrons) are called nucleons. Anuclide is an atom with a particular number of protons and neutrons. An unstable nucleus that decays spontaneously is radioactive, and its emissions are collectively called radioactivity. Isotopes that emit radiation are Saylor URL: http://www. saylor. org/books. Q: What are the subatomic particles of the nucleus called? Choices: - cores - eukaryotes - protons - nucleons A:
A: nucleons

Q: Answer the following question given this paragraph: Blizzards are dangerous storms. The wind may blow the snow into deep drifts. Along with the poor visibility, the snow drifts make driving risky. The wind also makes cold temperatures more dangerous. The greater the wind speed, the higher the windchill. Windchill is what the temperature feels like when the wind is taken into account. It depends on air temperature and wind speed ( Figure below ). Higher windchill will cause a person to suffer frostbite and other harmful effects of cold sooner than if the wind isn't blowing. Q: What weather term describes what the temperature feels like when the wind is taken into account? Choices: - windshield - freezing point - humidity - windchill A:
A: windchill

Q: Answer the following question given this paragraph: Bones are the main organs of the skeletal system. The skeletal system also includes cartilage and ligaments. Q: Bones are the main organs of what system, which also includes cartilage and ligaments? Choices: - lymphatic system - digestive system - endocrine system - skeletal system A:
A: skeletal system
