1- Arrange the following elements in order of increasing
metallic character: Fr, Sb, Cd, Cl, La, As.
Rank elements from least to most metallic character.
2- Only trace amounts of the synthetic element darmstadtium,
atomic number 110, have been obtained. The element is so highly
unstable that no observations of its properties have been possible.
Based on its position in the periodic table, propose three
different reasonable valence electron configurations for this
element.
