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.

there are atoms of different elements is sodium atom
<h2>Answer:</h2>
pOH = 4.6
<h2>Explanations:</h2>
The sum of pH and pOH of a solution is 14as shown:
Given the following parameter
pH = 9.4
Substitute the given parameters into the formula to have:
Hence the pOH of the solution of pH of 9.4 is 4.6

Answer: What type of chemical reaction is rusting of iron?
Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.
