WebThe trend of Charge Density in the Periodic Table. The charge of the ion formed from a particular element remains constant on moving down a group, but the outer electron moves further away from the nucleus due to more shielding from more full inner electron shells, and the increase in shielding is greater than the increase in proton number. Web29 de out. de 2024 · They are high in density, and in such elements, the number of electrostatic forces required to break the electrons bond is very high. This results in a very high melting point that requires more energy to break the bonding between electrons. Apart from that, there are also many elements that have lower melting points due to weaker …
