The melting point for potassium (K) is 63.5 °C whereas melting point of barium (Ba) is 727 °C.

<h3>Reason for high melting point</h3>

The melting point of barium is higher than potassium because of the presence of metallic bonding in the giant structure of a barium metal is very strong. These metallic bonds requires large amounts of energy for breaking.

While on the other hand, potassium has large atomic size than barium so the melting of potassium is lower than barium so we can conclude that melting point of potassium is lower than barium atom.

Which causes waves in the ocean to occur?​
galina1969 [7]

Answer:

Explanation:

C. energy being transferred from wind

Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.  The gravitational pull of the sun and moon on the earth also causes waves.

What is the VSEPR model of CB4I?
sesenic [268]

Answer:

Molecular geometry Vsepr

According to VSEPR, the valence electron pairs surrounding an atom mutually repel each other; they adopt an arrangement that minimizes this repulsion, thus determining the molecular geometry. This means that the bonding (and non-bonding) electrons will repel each other as far away as geometrically possible.
