An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. classify the statements about this absorption and emission process as true or false. true false it takes less energy to ionize the electron from the n= 4 state than from the ground state. on average, the electron is closer to the nucleus in the n= 4 state than in the n = 1 state. the wavelength of light emitted when the electron falls from n = 4 to n= 2 is shorter than the wavelength of light emitted when the electron falls from n = 4 to n = 1. the n= 4 excited state is the first possible excited state. the wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of light emitted when the electron falls from n = 4 to the ground state.

explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
