State the meaning of the term ground state.
Show the electronic configuration of vanadium using electrons in boxes notation.
Deduce the total number of electrons in the p sub-shells in a vanadium atom.
Complete Table 1.1 for the isotopes $^{93}_{41}\text{Nb}$ and $^{181}_{73}\text{Ta}$, giving the proton number and the neutron number.
Define the term relative isotopic mass.
A sample of pelopium is made up of $90.9\%$ by mass $^{93}_{41}\text{Nb}$ and $9.1\%$ by mass $^{181}_{73}\text{Ta}$. Calculate the theoretical relative atomic mass of pelopium from these data and Table 1.1. Give your answer to two decimal places. Show your working.
