Mendeleev accurately predicted the properties of gallium(eka aluminium). In his justification of properties he says(according to image given) the melting point of the element would be low. What could have been his insight considering the fact that melting points of aluminium and indium are 660.3°C and 156.6°C respectively?

$\begingroup$ What do you think his insight was? $\endgroup$– ringoCommented Apr 9, 2019 at 18:35

$\begingroup$ All I could think of is that it's melting point should be intermediate to that of aluminium and indium $\endgroup$– MaanCommented Apr 9, 2019 at 19:05

$\begingroup$ Actually it's m.p. is lowest in the group not intermediate, but "low m.p." could be applied maybe even to Al. $\endgroup$– MithoronCommented Apr 9, 2019 at 22:01

$\begingroup$ I know that it has the lowest melting point in the group ,but in Mendeleev's case he would not have encountered the element right? $\endgroup$– MaanCommented Apr 10, 2019 at 2:10

$\begingroup$ Sorry if the question was too basic, but all I was wondering was what Mendeleev was thinking when he mentioned low melting point of "eka-aluminium" ?Also was it relative to all other elements of the periodic table or pertaining only to the particular group? $\endgroup$– MaanCommented Apr 11, 2019 at 5:12
