When an electrons moves from an excited state to the ground state, it would release energy. An electron in the excited state would mean that it contains high kinetic energy so to move to a lower state some of these energy should be released.

Maggie is solving a chemistry riddle her clue is to take the number of valence electrons in halogens and subtract it by the numb

Novay_Z [31]

The answer to the riddle Maggie is solving is 6

To determine the answer to the riddle Maggie is solving,

We will subtract the number of valence electrons in halogens by the number of valence electrons in alkali metals.

First, let us define what is meant by valence electrons

Valence electrons are those electrons that reside in the outermost shell surrounding an atomic nucleus.

Now, we will the determine the respective number of valence electrons in halogens as well as the number of valence electrons in alkali metals.

For Halogens

Halogens are the group 17 (group 7A) elements in the periodic table. Examples are Fluorine, Chlorine, Bromine etc.

Halogens have 7 electrons in their outermost shell

For Alkali metals

Alkali metals are the group 1 metals. Examples are Lithium, Sodium, Potassium etc.

Alkali metals have 1 electron in their outermost shell

Now, for the answer to the riddle,

Answer to the riddle = Number of valence electrons in halogens - Number of valence electrons in Alkali metals

Answer to the riddle = 7 - 1

∴ Answer to the riddle = 6

Hence, the answer to the riddle Maggie is solving is 6

The Wolff-Kishner reaction involves the reaction of an aldehyde/ketone with hydrazine in the presence of KOH. The process is use

Ivan

Answer:

in the attached image is the reaction mechanism.

Explanation:

The first reaction (reaction 1) shown in the attached image is the Wolff-Kishner reduction, which is characterized when the carbonyl is reduced to an alkane in the presence of a hydrazine and a base. In reaction 1, the aldehyde reacts with hydrazine to produce oxime. This mechanism begins with the attack of the amine on the carbonyl group. Proton exchange happens and the water leaves the molecule.

In reaction 2, the KOH is deprotoned in nitrogen and organized to form the bond between the nitrogen molecule. this deprotonation releases the nitrogen gas
