The quantum numbers for the last valence electron in nickel are (3, 2, 0, -½).

The electron configuration of nickel is [Ar]4s²3d⁸

The last electron added is a 3d electron, so n = 3 and l = 2.

We construct a table of quantum numbers.

Element n l mₗ mₛ

Sc 3 2 2 +½

Ti 3 2 1 +½

V 3 2 0 +½

Cr 3 2 -1 +½

Mn 3 2 -2 +½

Fe 3 2 2 -½

Co 3 2 1 -½

Ni 3 2 0 -½

The quantum numbers for the last electron in nickel are (3, 2, 0, -½).

If an electron is added to an atom, that electron will be a __________. Select the correct answer below:

yaroslaw [1]

I think it s none of above if we add an electron to an atom it becomes a negative ion. Lets say we have atom A And B like for example A is more electronegative it wants more electrons it pulls one from B so one electron is added and i believe it s called elctrovalency.

(core electron are the non participating electrons from the last shell b also non part electrns valence are the ones who are used to make bonds )

How many valence electrons are transferred to the oxygen atom from potassium atoms in the formation of the compound potassium ox

Sonbull [250]

Answer: 2

Explanation: Potassium, K, has only 1 valence electron, 4s^1. Oxygen, O, needs 2 more electrons to complete its valence shell to make 8 electrons. That means 2 K atoms will combine with 1 O atom, to produce K2O, potassium oxide. Both K electrons are stolen by the single O atom, so 2 electrons are transferred.

Which energy changes in the enthalpy of solution are endothermic, and which are exothermic?

snow_tiger [21]

When energy is needed in order for the reaction to happen, then that reaction is known as endotermic. When the reaction has as a result energy then it is exotermic. An example of an endotermic reaction would be photosynthesis, for an exotermic: combustion.
