Metallic bonds are not so strong as covalent and ionic bonds.
The weakest interparticle attractions exist between particles in gases, which are dominated by weak van der Waals forces. These forces are relatively weak compared to the stronger attractions seen in liquids (such as hydrogen bonding) and solids (such as metallic or covalent bonds).
the bonds between particles in a liquid are very weak
The intermolecular forces between rubidium atoms are primarily metallic bonds, as rubidium is an alkali metal. In the solid state, these metallic bonds result from the attraction between the positively charged metal ions and the sea of delocalized electrons. In liquid form, while the metallic bonding remains, the atoms can move more freely, but the forces still primarily reflect metallic interactions rather than van der Waals forces or hydrogen bonding. Overall, rubidium exhibits relatively weak intermolecular forces compared to more covalently bonded substances, contributing to its low melting and boiling points.
To melt Krypton, you would need to overcome the intermolecular forces between Krypton atoms. These forces are relatively weak compared to the covalent or metallic bonds found in molecules and solid structures.
Alkali metals contribute only one valence electron
Alkli metal (i.e li-lithium,Na-sodium,K-Pottasium)has weak interatomic force of atterection
In metallic solids, the attractive forces that stabilize the structure primarily come from metallic bonds, which are formed by the sharing of electrons among the metal atoms. These bonds are strong and are responsible for the high melting points and conductivity typically associated with metals. Additionally, metallic solids may also experience some degree of Van der Waals forces between atoms.

Strong chemical bonds in solids are ionic bonds, covalent bonds in giant network molecules and metallic bonds. Weak bonds in solids holding discrete molecules together are hydrogen bonds in solid H2O, HF, NH3 Weak intermolecular forces including dispersion forces and permanent dipole interactions

Alkali metals contribute only one valence electron
Metallic bonding is weaker than ionic and covalent bonding because metallic bonds result from the attraction between positively charged metal ions and delocalized electrons, which are not held as tightly as valence electrons in covalent or ionic bonds. Additionally, metallic bonds are less directional compared to covalent bonds, resulting in weaker interactions between atoms.
