The illustration above depicts a string being stretched and then released. changes in both potential and kinetic energy occur during this process. which statement most accurately describes the changes in potential or kinetic energy? a) the kinetic energy is continually increasing throughout the entire process b) the potential energy is continually increasing throughout the entire process c) the potential energy is increasing through steps a, b, & c and then decreases d) the potential energy is decreasing through steps a, b, & c and then increases

Which statement describes covalent bases? they have hydroxide ions. they produce hydrogen ions. they are often amines. they are named the same as ionic compounds.

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
