Atoms form chemical bonds with one another because the bonded arrangements... Select one:
O a. are smaller than the group of unbonded atoms are.
O b. have lower potential energy than the unbonded atoms do.
O c. have a lower electronegativity difference than the unbonded atoms do.
O d. have less electric charge than the unbonded atoms do.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
