Explain each of the following observation the melting point of lithium is higher than that of potassium

Chemistry

lakkis [162]2 years ago
5 0

Due to its small size, lithium has a high melting and boiling point.

<h3>Why does lithium have high melting and boiling point explain?</h3>

With only one valence electron to contribute to the metallic lattice, lithium and potassium are both alkali metals. We could infer that the metallic bonding is less strong between the electron cloud and the larger potassium cation than it is in the lithium structure. This means that because lithium creates a smaller cation, the electrostatic force in this situation should be greater also Lithium has high ionization energy and a high melting and boiling point because of its small size. As a result, its crystal structure has an extremely high binding energy.

<h3>Alkali metals</h3>

The chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium make up the alkali metals (Fr). They make up group 1, which is located in the s-block of the periodic table, along with hydrogen.

What would happen to the volume of the container if the pressure is increased by a factor of 2​
telo118 [61]

Answer:

volume of the container will decreases if pressure increases.

Explanation:

According to Boyle's law:

Pressure is inversely proportional to volume which means if pressure of a gas increases the volume of the gas will decreases as gas molecules will collide and come closer forcefully so volume will decreases. And its formula for determining volume and pressure is:

<em>PV=nRT</em>

where "R" is a ideal gas constant

"T" is temperature and

"n" is number of particles given in moles while "V" is volume and "P" is pressure.

Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process
Arlecino [84]

Lithium metal reacts with nitrogen gas to form lithium nitride the balanced chemical equation will be 6Li + N₂ → 2Li₃N.

<h3>What is a balanced chemical reaction?</h3>

In a balanced chemical reaction, the number of moles that are present at the side of the reactant must be always equal to the side of product formation this is known as a balanced chemical equation.

The balanced chemical reaction will be 6Li + N₂ → 2Li₃N.

Here 6 moles of lithium is reacting with one nitrogen but as it is in gaseous state it is N₂ after reacting with lithium it will give two moles

Therefore, balanced equation will be 6Li + N₂ → 2Li₃N
