In the mid-1900s, most scientists used the bohr atomic model to study atoms. in the bohr model, electrons move in set paths around the atom's nucleus.
in current atomic models, electron clouds are shown around the atom's nucleus. electron clouds are regions where electrons are likely to be found.
what is a limitation of current atomic models as compared to the bohr atomic model?
a. current atomic models do not indicate the position of the nucleus within the atom's structure.
b. current atomic models do not show how many electrons an atom has.
c. current atomic models do not show where the electron is but only where the electron is likely to be.

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
