Periodic Table Trends Chemical Properties The d BlockPotpourri

In the Periodic Table, reading left to right, top to bottom, elements are arranged in order of 1-1

Atomic number or number of protons in the nucleus

An element has 13 electrons orbiting the nucleus. In which group of the periodic table will it be found 1-2

Group 3

How many electrons will chlorine have in its valence shell? 1-3

7 valence electrons

1-4 Give the symbol of an element in the same period and another element in the same group as Sulfur

Anything in period 3 and anything in group 16

1-5 Give the names of groups 1,2,7, and 8

Alkali metals, Alkaline earth metals, halogens, and Noble gases

What element has the highest electronegativity? 2-1

Fluorine

2-2 Which of the following has the smallest radius K K + Ca Ca 2+

Ca 2+

2-3 How does electronegativity change going down a group and why?

Decreases going down a group because of shielding of the nucleus by inner energy levels

2-4 How does atomic radius change going across a period and why?

Decreases as nuclear charge increases and nucleus-electron attraction increases

2-5 How does the radius of an anion compare with its parent atom and how does the radius of a cation compare with its parent ion?

Anion:Larger Cation:Smaller

3-1 What properties of the halogens increases from F to I

Atomic Radius or Melting Point

3-2 What sort of compounds form when oxygen reacts with elements on the left side of the Periodic Table?

Ionic compounds (Ionically bonded Oxides)

3-3 Name the following Compound KBr

Potassium Bromide

3-4 Name the following Compound AlI 3

Aluminum Iodide

3-5 When dissolved in water, oxides bonded to hydrogen atoms act as bases to give alkaline solutions. Write out the Chemical equation for this reaction

See notes

4-1 What is a ligand? Give an example

Species that can donate a pair of non-bonding electrons, ammonia, water, cyanide ion

4-2 Why are transition metals frequently colored?

Because of the movement of electrons between d-orbitals

4-3 One of these things is not like the other: What d-block elements are not considered to be transition metals and why?

Sc and Zn. Scandium has only 1 d-block electron and can’t have multiple oxidation states, Zn has a full 10 d-block electrons.

4-4 Give an example of an oxide that would be a solid and an oxide that would be a gas at room temperature

1.Any ionically bonded oxide 2.Any covalently bonded oxide

4-5 Give two examples of catalysts, one industrial, one biological
