No, it would be unlikely that an alien planet have no transition metals. Perhaps in the early universe the first planets formed were metal poor but as super-nova continue to fill inter-stellar space with heavier nucelotides the newer planets will always have some taint of metal in them.
Among the naturally occurring elements, the most likely one would be cesium, the least electronegative of all elements. In practice, any of the other alkali metals and any of the alkaline earth metals would usually react readily with chlorine gas, as would many of the transition metals.
Elements in the middle of the periodic table are metals, and they are probably best categorized as transition elements.
Early transition metals are does starting at the beginning of the transition metals (i.e. Sc) and going through about d5 which would be Mn. These metals are less electron rich as compared to the so-called "late" transition metals and the chemistry of each is somewhat different and definitely unique. Hardness and softness of the each of these groups changes (see Hard Soft Acid Base Theory) as does the stable oxidation states and coordination numbers.
it would be transition elements/metals, as they are malleable metals, meaning they can be hammered into shapes.
it belongs to the transition metals so, I would say it is a SOLID.
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
why would the heavier metals sink to the center during the formation of the earth is like
The transition metals are the group on the periodic table that forms ions with different charges. This is because the transition metals cannot easily gain a stable electron configuration. Some of the transition metals, such as silver, do form only one ion, however. wtf why is this here ???? bixth
No. Noble gases, halogens, and nonmetals are on the right side of the periodic table. Metals including, alkali metals, alkaline earth metals, and transition metals are all located on the left/center.
The mass of an element increases as you go down the periodic table. The heaviest discovered (synthesized) metals are in the bottom row of the transition metals group.

If a dwarf star crashed into a planet,the planet would likely explode.
