Transition metals
unequal localization of the electron densities
When chains are long many Vander Woals bonds are formed.So inter molecular forces become stronger.And the molecular mass also high in long chains.So they are densities also high.
Generally, metals have a high density relative to other elements, but there are a few which dont correspont to this rule. But if it was a simple yes or no question, it would be HIGHH!!!! The density of metals is very variable: from lithium (0,534 g/cm3) to osmium (22,61 g/cm3) - from low density to high density.
TRANSITION ELEMENTS HAVE d-ORBITAL IN THEIR SHELL WHICH HAS LOW SHIELDING EFFECT. DUE TO WHICH THEY HAVE HIGH EFFECTIVE NUCLEAR CHARGE. SO, HIGH POLARIZING POWER.
the electron density of pi bonds are located above and below the line connecting the nuclei of the atoms bonded
no, because some of them is not high ,some of them are low densities.
not car engines, but other engines used for industrial purposes can have that high of a capacity.
mercury, Venus and earth
unequal localization of the electron densities
These products serve similar purposes as automotive lubricants, with added endurance capacity, which allows them, for example, to prevent rust from high-temperature steams.
When chains are long many Vander Woals bonds are formed.So inter molecular forces become stronger.And the molecular mass also high in long chains.So they are densities also high.
There are devices called thyristors which are used for switching purposes in high voltage levels. Thyristors are of different typesSCRIGBDiacTriac, etc.Apart from these MOSFETs, a type of transistor, are also used in high voltage switching applications.
R- Selected species have high population densities while k-selected species have lower population densities
They tend to aggregate at high densities under rocks.
- many nonmetals are gaseous or liquids- densities are not high- hardness of solid elements is not high- nonmetals form frequently anions- nonmetals form frequently compounds with covalent bonds
Rackway
because the great amount of pressure creates higher density
