Q: What forms when an atom gains electrons? Read this paragraph and choose the correct option from the provided answers: Anions form when an atom gains electrons. Nonmetallic atoms typically gain enough electrons to obtain the same electron configuration as the nearest noble gas. All the elements in Group 17 have seven valence electrons, which are arranged into an outer configuration of n s 2 n p 5 . To achieve a noble gas configuration ( n s 2 n p 6 ), each of these elements needs to gain just one electron, resulting in an anion with a 1 charge. Similarly, Group 16 elements can obtain an n s 2 n p 6 valence configuration by forming ions with a 2 charge, and the Group 15 nonmetals will form ions with a 3 charge. Naming anions is slightly different than naming cations. The end of the element's name is dropped and replaced with the ide suffix. For example, when the chlorine atom (Cl) gains one electron, it becomes the chloride ion (Cl - ). This structure has the same electron configuration as the noble gas argon. Similarly, sulfur can gain two electrons to become the sulfide ion (S 2- ), which also has a noble gas configuration. Choices: - cations - bonds - crystals - anions A:
(Answer)
anions

Q: Water in its solid state is commonly known as what? Read this paragraph and choose the correct option from the provided answers: During the water cycle, water occurs in three different states: gas (water vapor), liquid (water), and solid (ice). Many processes are involved as water changes state in the water cycle. Choices: - carbon dioxide - sea - glass - ice A:
(Answer)
ice

Q: What physical property of matter reflects how closely packed the particles are? Read this paragraph and choose the correct option from the provided answers: Density is an important physical property of matter. It reflects how closely packed the particles of matter are. Density is calculated from the amount of mass in a given volume of matter, using the formula:. Choices: - volume - strength - diameter - density A:
(Answer)
density
