For the main group elements, atomic size increases down the
group. For the transition metals, how does the atomic size change
from the 4d series to 5d series? What is the factor that causes the
difference between these two types of elements?

Transition metals can be distinguished from main-group metals by the fact that transition metals have higher relative atomic weights than main-group metals. only the main-group mctals can form complex ions. main-group metals have only +1 or +2 oxidation states. transition metals have a greater tendency to form colored compounds than main- group metals. main-group metals have higher relative atomic weights than transition metals.

Explain why the effective nuclear charge increases across a row for the main group elements, but is nearly constant across a period in the transition metals. Explain why transition metals do not show the same strong trend in atomic radius as the main group elements (and even start to get larger across the row). Explain why the ionization energies of the transition metals are very similar to each other and do not follow the same trends as the main group...

Atomic radius Nbonding The radius of an atom describes the distance between the nucleus and the outermost electron. This distance is very small so it is often reported in picometers (101 m) or angstroms (10-10 m). One way of measuring the atomic radius is to observe the distanc between bonding atoms. The distance between the nuclei of the bonding atoms is equal...

Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...
