Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. These are also known as constructive boundaries. ... Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. Subduction zones are marked by oceanic trenches.
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.

They are classified as Decomposers
As you move across a period, the atomic radii decreases. ... As you move across a period, electrons are added to the same energy level while protons are also being added. The concentration of more protons creates a higher effective nuclear charge.
