A student observes sediments as they are carried downstream by a rapidly flowing river. The student argues that the river is depositing the sediments. Is the student correct? A.
Yes. The river is depositing the sediments.
B.
No. Deposition is the movement and eventual settling of whole rocks, not rock fragments and sediments.
C.
No. The river is eroding the sediments; deposition will happen when the river slows and the sediments settle on the riverbed.
D.
No. The sediments still have the same chemical composition as the rock they came from; deposition follows chemical changes only.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
