What is the electronic configuration of Mn (Atomic Number 25) in its ground state?
The correct answer is 1s2 2s2 2p6 3s2 3p6 4s2 3d5 because the atomic number of Mn (Manganese) is 25. In the provided options, this configuration represents the correct electron configuration for Mn in its ground state. Mn has 25 electrons, and this configuration accounts for the outermost electrons, following the rule of filling energy levels from low to high.

What gives a flash on a photographic plate when exposed to positive rays?
ZnS (zinc sulfide) is a type of photoemissive material that emits light when exposed to positive rays, such as ultraviolet radiation, due to its ability to release electrons. This property is used in photographic flash devices.
3464
What is the primary reason for the high second ionization potential of alkali metals?
Alkali metals have a high second ionization potential because removing a second electron would require breaking into a stable inert gas configuration, which is energetically unfavorable.
3465
Which halogen has the greatest tendency to accept an electron?
Chlorine has the highest electron affinity among the given options, meaning it has the greatest tendency to accept an electron and form a negatively charged ion.
3466
What is the Ionization energy of Hydrogen approximately equal to?
The ionization energy of hydrogen refers to the minimum energy required to remove an electron from its orbital. In terms of electron volts (ev), the correct answer is 13.6 ev. The other options provided are incorrect values: 10.54 ev, 12.54 ev, and 17.56 ev.

What will be the tendency when the standard reduction potential has a greater value?
A higher standard reduction potential indicates a greater tendency for a species to gain electrons (be reduced) and release other species (oxidize them).
3470
A higher electron affinity value indicates that an atom tends to gain an electron more _______
Electron affinity is a measure of an atom's tendency to gain an electron. A higher electron affinity value indicates that an atom has a greater tendency to gain an electron, making it more likely to form a negatively charged ion.
