Given hypothetical elements Q, R, S and T that are found on the same period. Their respective properties are presented in a table below:?
Which among these elements has the most metallic character?Arrange the elements in increasing atomic size (from smallest to biggest).From the given data, what can you deduce about the valence of element R? Explain your answer.

Most metallic = T
Size: R < S < T < Q
R looks to be a noble gas and as such would have 8 valence electrons
