1.
The electronic configurations of both Chromium (24Cr) and Copper (29Cu) are anomalous due to the enhanced stability associated with:
Half-filled (3d5) and completely filled (3d10) d-subshells respectively
Pairing of all electrons in the outer valence level
High electronegativity differences
Completely empty 4s subshells
2.
If f(x) = |x - 3|, the derivative f'(3) at x = 3:
Equals 1
Equals -1
Does not exist because the left-hand derivative (-1) does not equal the right-hand derivative (+1)
Equals 0
3.
The volume expansion coefficient at constant pressure (alpha_v) of an ideal gas is physically measured using:
A torsion balance
A hydrometer
A venturi meter and manometer
Joly's bulb apparatus or Charles's apparatus with a dry mercury droplet index
