Answer the following question given this paragraph: The transition elements have many properties in common with other metals. They are almost all hard, high-melting solids that conduct heat and electricity well. They readily form alloys and lose electrons to form stable cations. In addition, transition metals form a wide variety of stable coordination compounds, in which the central metal atom or ion acts as a Lewis acid and accepts one or more pairs of electrons. Many different molecules and ions can donate lone pairs to the metal center, serving as Lewis bases. In this chapter, we shall focus primarily on the chemical behavior of the elements of the first transition series. Q: Typically hard, high-melting solids that conduct heat and electricity well, the transition elements have many properties in common with other what? A:
OPTIONS:
- oils
- deposits
- organics
- metals

Answer: metals

Q: Answer the following question given this paragraph: The information listed at the right of the label tells you what to look for. At the top of the label, look for the serving size. The serving size tells you how much of the food you should eat to get the nutrients listed on the label. A cup of food from the label pictured below is a serving. The calories in one serving are listed next. In this food, there are 250 calories per serving. Q: What tells you how much of the food you should eat to get the nutrients listed on the label? A:

OPTIONS:
- regular size
- scoop size
- longer size
- serving size

A: serving size

input: OPTIONS:
- atoms
- molecules
- cations
- ions Now, answer this question: Answer the following question given this paragraph: So far, we have discussed elements and compounds that are electrically neutral. They have the same number of electrons as protons, so the negative charges of the electrons is balanced by the positive charges of the protons. However, this is not always the case. Electrons can move from one atom to another; when they do, species with overall electric charges are formed. Such species are called ions. Species with overall positive charges are termed cations, while species with overall negative charges are called anions. Remember that ions are formed only when electrons move from one atom to another; a proton never moves from one atom to another. Compounds formed from positive and negative ions are called ionic compounds. Individual atoms can gain or lose electrons. When they do, they become monatomicions. When atoms gain or lose electrons, they usually gain or lose a characteristic number of electrons and so take on a characteristic overall charge. Table 3.6 "Monatomic Ions of Various Charges" lists some common ions in terms of how many electrons they lose (making cations) or gain (making anions). There are several things to notice about the ions in Table 3.6 "Monatomic Ions of Various Charges". First, each element that forms cations is a metal, except for one (hydrogen), while each element that forms anions is a nonmetal. This is actually one of the chemical properties of metals and nonmetals: metals tend to form cations, while nonmetals tend to form anions. Second, most atoms form ions of a single characteristic charge. When sodium atoms form ions, they always form a 1+ charge, never a 2+ or 3+ or even 1 charge. Thus, if you commit the information in Table 3.6 "Monatomic Ions of Various Charges"to memory, you will always know what charges most atoms form. (In Chapter 9 "Chemical Bonds", we will discuss why atoms form the charges they do. ) Table 3.6 Monatomic Ions of Various Charges H+ Na+ K+ Ions formed by losing a single electron. Q: Electrons can move from one atom to another; when they do, specimens called what, with overall electric charges, are formed? A:
A:
output: ions

OPTIONS:
- central nervous system
- posterior division
- somatic nervous system
- parasympathetic division
Answer:
parasympathetic division
