niobium -Nb
Boron
Any element in the group 6 and period 3 (IUPAC version of periodic table).

xenon increases from left to right across periods (first ionization energy)
no you get a random element and you dont change it
Strontium
tin ;P
Not necessarily, the number of electrons depend on the period in which the element is contained. For instance the first period ends at 2, second and third at 8, fourth and fifth at 18, sixth and seventh at 32.
This chemical element is tin (Sn).
Boron
This element is tin (Sn).If you mean carbon family then the element is tin (Sn).
Iodine
