Question

Why do Mn & Tc have low melting points?

V Bikesh Kumar · Answer

transition metals have high melting point
M P order is: 5d>4d>3d
along the particular series, the M P 1st increases, then reaches
to maximum then starts decreasing there is a sharp decline in the M
P in between d series the melting point of transition element is
high due to stronger M-M interaction and it becomes stronger wid
increase in the unpaired electron which happens til the middle of
the series
after that 1 electron starts pairing up and M-M interaction
becomes weaker due to more repulsion
Mn(manganese) and Tc(technesium) have exceptionally ;ow melting
point due to stable configuration , electrons are less delocalised
& M-M interactions is comparitively weaker
is this ok????????
