Which element appears below tin?
Lead element appears below tin.It has symbol Pb and atomic number 82.
Which number on the periodic table determines the number of electrons in the atoms of the elements?
The atomic number which is equal to the number of protons or electrons in a neutral atom.
What are the three element groups called?
Periodic table has 18 groups; see the link below.
How can you predict the placement of an unknown element on a periodic table based on physical an chemical properties?
You look at trends. An element is likely to have properties somewhere between the element above it and the element below it; if there's nothing below it (or above it), then you can follow the general trend up (or down) that column and extrapolate.
What is a number written to the right of a chemical symbol?
a subscript Number of atoms of that element in the molecule.
