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.

subtract the mass of the filter paper (0.27 g) from the mass of the paper and copper (0.98 g). Record the difference in the data
vova2212 [387]
When measuring copper that is collected on a filter paper, the mass measurement obtained will include both the mass of the filter paper and copper.
therefore we have to find the mass of the empty filter paper before copper is on the paper.
the mass of the filter paper alone is 0.27 g
then the mass of copper and filter paper is 0.98 g
therefore to find the mass of copper alone we have to take the difference between the 2 masses
mass of copper = (mass of copper + filter paper ) - mass of filter paper
                          = 0.98 g - 0.27 g 
mass of copper = 0.71 g
