Question

Why mangnese and techtinium has lower melting point?

Answer 1

because they have open cage like structure

Answer 2

Manganese and Techtinium has lower Melting and boiling point ;

# Because of the following reasons :--

• With decrease in unpaired or vacant electrons or orbitals, Melting and Boiling point also decreases .

• Thus, there is weak mettalic bonding further due to less unpaired electrons .

• It reduces Enthalpy of Atomization value .
