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.

Express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. For example, [He]2s22p2 should be entered as  [He]2s^22p^2.Enter your answers separated by commas.

Solutions

Expert Solution

1. In the periodic table metallic character decreases as you move across the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down the periodic table.

2.

According the given circumstances.

[Rn]5f^146d^87s^2

Possibility 1: [Rn]7s^15f^146d^9
Possibility 2: [Rn]7s^25f^146d^8
Possibility 3: [Rn]7s^05f^146d^1
