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.

Answer:
pH = 7.01
Explanation:
The pH can be calculated using the formula:
pH = -log[H⁺]
In this formula, [H⁺] represents the concentration of H⁺. Since you have been given this value, you can easily find the pH.
pH = -log[H⁺]
pH = -log[9.71 x 10⁻⁸]
pH = 7.01
Answer:
trigonal planar
Explanation:
The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.
There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle. The bond angle is 120 degrees.
