Do most transition metals have higher or lower melting points than the representative elements?

Yes, transition metals have higher melting points. This is due to having very strong bonds. This means that a larger amount of energy is needed in order to break them down or bring them to the melting points.

What is the relationship between melting point and atomic number for group seven elements?
As the atomic number increases so does the melting point, meaning the the molecules get stronger therefor you need a higher melting point to break the molecules.
How are transition elements different from other elements in s and p blocks on periodic table?
It's a transition where an electron jumps from one d orbital to another. Normally these are degenerate (the d orbitals have the same energy), but under some conditions, such as the presense of ligands, the degeneracy can be removed so that there is a specific energy (and therefore wavelength) associated with these transitions. These sorts of transitions sometimes have energies located in the visible band, and it's one reason transition metal ions (and complex ions in particular) tend to be highly colored.
Which has a higher melting point Neon or Argon?
Argon has the higher melting point.
What has a higher melting point iron or granite?
Granite has a higher melting point than iron.
Which substance ionic or covalent has a higher melting point?
Generally the ionic molecules has a higher melting point.
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
How high can melting points get?
At 6000K all elements will turn into a gas.there could be hundreds of unknown elements in space so there could be even higher melting points
Would metals or non metals tend to have a higher melting point?
Tungsten has the highest melting point of the elements and it is a metal.
Why d block elements called transition element?
Because the d-orbitals become split into two groups one having higher and other having lower energy so the transition of electrons within these groups continuously takes place which is also responsible for different colours of their compounds.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
What element is a transition metal?
Transition elements are both ductile and malleable, and conduct electricity and heat. The transition metals are all of the elements located in the d-block of the Periodic Table. 21 (Scandium) -- 29 (Copper) 39 (Yttrium) -- 47 (Silver) 57 (Lanthanum) -- 79 (Gold) 89 (Actinium) and all higher numbers.
Why do metals share properties with other transition metals in their period?
The physical properties of transition metals are determined by their electron configurations. Most transition metals are hard solids with relatively high melting and boiling points. Differences in properties among transition metals are based on the ability of unpaired d electrons to move into the valence level. The more unpaired electrons in the d sublevel, the greater the hardness and the higher the melting and boiling points.

What is the effect of change in pressure in melting point?
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
Does CaO or CS2 have a higher melting point?
CaO has a higher melting point.
Which has a higher melting point Neon or Argon?
Argon has the higher melting point.
