Answer the following question given this paragraph: How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. Metalloids have from three to six electrons in their outer energy level. Boron, pictured in the Figure below , is the only metalloid with just three electrons in its outer energy level. It tends to act like metals by giving up its electrons in chemical reactions. Metalloids with more than four electrons in their outer energy level (arsenic, antimony, and tellurium) tend to act like nonmetals by gaining electrons in chemical reactions. Those with exactly four electrons in their outer energy level (silicon and germanium) may act like either metals or nonmetals, depending on the other elements in the reaction. Q: How metalloids behave in chemical interactions with other elements depends mainly on the number of what, in the outer energy level of their atoms? Choices: - protons - positrons - neutrons - electrons A:
(Answer)
electrons
Ques: Answer the following question given this paragraph: The most noticeable magnetic activity of the Sun is the appearance of sunspots. Sunspots are cooler, darker areas on the Sun's surface ( Figure below ). Sunspots occur in an 11-year cycle. The number of sunspots begins at a minimum. The number gradually increases to the maximum. Then the number returns to a minimum again. Q: What is the year cycle that sunspots occur? Choices: - 12 - 15 - 22 - 11 A:
Ans: 11
