Which statement compares the attractive forces that hold particles together? A. Covalent bonding and Van der Waals forces join molecules together; ionic and hydrogen bonding produce compounds.
B. Metallic bonds and Van der Waals forces are weakly attractive; covalent and hydrogen bonds are strongly attractive.
C. Metallic and covalent bonds are strongly attractive; hydrogen bonding and Van der Waals forces are weakly attractive.
D. Metallic and covalent bonds are weakly attractive; hydrogen bonding and Van der Waals forces are strongly attractive.
Answer is C- Just got it right

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.
