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

c most likely

hop this let me know if it is wrong

what are the choices?

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
