Teacher Says Yttrium?
« on: December 12, 2006, 01:24:45 AM »
My chem teacher says that strontium shares more properties with yttrium...

However I objected and told him it was Barium on account of the atomic number of yttrium(which follows strontium), exceeds the atomic number of strontium by one, and Barium is 18 atomic numbers after strontium but it falls directly beneath strontium?

Who is right?

It is obviously Barium since elements in the same group will trend to have similar chemistry.

The periodic table is organised such that elements in the same column will have similar properties.  Chemical properties and many physical properties are based on the number of valence electrons rather than the mass.
