calculate the percent ionic, the percent covalent, and the bond length (in picometers) of a chemical bond between sodium and chlorine.
for sodium—atomic radius: 186 pm; covalent radius: 154 pm; ionic radius: 116 pm.
for chlorine—atomic radius: 97 pm; covalent radius: 99 pm; ionic radius: 167 pm.
70 percent ionic, 30 percent covalent, 283 pm
74 percent ionic, 26 percent covalent, 283 pm
30 percent ionic, 70 percent covalent, 253 pm
26 percent ionic, 74 percent covalent, 253 pm

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
