Silvery solids with low densities and low melting points are alkali metals. These are located in group one on the periodic table.
The Alkali Metals are: -lithium -sodium -potassium -rubidium -cesium -francium These metals are silvery solids with low densities and melting points.
in crystalline solids, the atoms are arranged in an ordered fashion and hence they have sharp melting points. amorphous solids, due to random arrangement of the atoms do not have sharp melting points.
Solids made of atoms
Covalent compounds, molecular solids, and metallic solids typically have lower melting points than ionic solids. Covalent compounds consist of molecules held together by weaker van der Waals forces, while molecular solids are composed of discrete molecules that interact through intermolecular forces. Metallic solids, while having variable melting points, often do not reach the high melting points characteristic of ionic solids due to their bonding nature.
They have a glass transition.

Molecular solids
the melting points differ to differant solids
Melting and boiling points are different for each compound or element.
Solids made of atoms
No, amorphous solids do not have sharp melting points like crystalline solids. Instead, amorphous solids soften over a range of temperatures as they transition into a more fluid state, making their melting behavior less well-defined.
Ionic compounds have a higher melting point.
Covalent solids and molecular solids typically have lower melting points than ionic solids. This is because the intermolecular forces holding covalent and molecular solids together are generally weaker than the electrostatic forces binding ionic solids, resulting in lower energy requirements for melting.

Metallic solids, while having variable melting points, often do not reach the high melting points characteristic of ionic solids due to their bonding nature.
Ionic solids typically have high melting points due to the strong electrostatic forces binding the positive and negative ions together in a lattice structure. When heated, these bonds must be overcome, requiring a significant amount of energy, resulting in high melting points.
They have a glass transition.
