'3d-, 4d-, 5d-, 6d-block' elements are in groups 3-12 in period 4, 5, 6 and 7 respectively.
Au or Pt are highly stable and they are noble metals as they do not react with oxygen readily
Generally precious metals as Au, Ag, Pt, Pd, Ir.
Au and Pt are some metals which do not react with O.
An atom of platinum (Pt) has 78 protons.
Transition metals (Blocks 3-12) contain only metals. This includes the groups known as d-block (3-12) and f-block (lanthanides and actinides).
For example platinum group of metals: Pt, Ir, Os, Pd, Rh, Ru.
Au or Pt are highly stable and they are noble metals as they do not react with oxygen readily
For example metals as Pt, Au, Os and other.
Generally precious metals as Au, Ag, Pt, Pd, Ir.
Au and Pt are some metals which do not react with O.
because u have to with some metals make a mixs ture so there
Pt. apparently soiled the bed. They were found lying in slightly yellow colored liquid. Or Pt. apparently soilde the bed. Pt. found lying in dark brown stool. Pt. cleaned up by nurse and appears to have no sign of rash. Pt. states he feels better.
An atom of platinum (Pt) has 78 protons.
metals are found ny digging up rock from the ground
Transition metals (Blocks 3-12) contain only metals. This includes the groups known as d-block (3-12) and f-block (lanthanides and actinides).
Heavy metals are typically found in the middle of the periodic table. These heavy metals are often also transition metals.
All metals are found in Russia, it is a big country.
