How many elements are there in 3rd transion elements?
There are eight third period transition elements on the periodic table.
How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
Why Na Mg are bridge elements?
NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
How many elements in the original period table of elements?
103
Period in chemistry?
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
How many elements are there in third period?
8 elements

How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
How many elements does the third period on the periodict table have?
8 - Na, Mg, Al, Si, P, S, Cl, Ar
Why does the octet rule not hold for many compounds containing elements in the third row of the periodic table and beyond?
Atoms of elements in the third period are less subject to destabilization from additional electron-electron repulsions.The third shell contains d orbitals that are relatively close in energy to 3s and 3p orbitals and provide an allowed energy state for extra electrons.Atoms of elements in the third period have the space and available orbitals to accommodate extra electrons.
Why Na Mg are bridge elements?
NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
Why sodium and magnesium are called bridge elements?
Because some of the second period elements show a diagonal relationship with the elements of third elements in showing a similar kind of propertiesLi and Mg show diagonal relationship Be and Al also and many more
