Why chromium is in d block?
This is because the D-Block in the Periodic Table is where the d-Subshell is being filled up. Chromium's d-Subshell is being filled up and is therefore in the D-Block.
The elements in the periodic table that have a completely filled outer subshell are known as?
noble gases.
Which subshell is represented by the actinides family?
The 4f subshell is being filled for the rare earth series of elements.
What section of the periodic table is the 4f subshell being filled?
Atoms first occupy the 4f level in the Lanthanide series, beginning with Cerium (Ce).
What elements are the transition elements?
the transition elements are those elements having a partially filled d or f subshell in any common oxidation state.
Why chromium is in d block?
This is because the D-Block in the Periodic Table is where the d-Subshell is being filled up. Chromium's d-Subshell is being filled up and is therefore in the D-Block.

What mostly fills the periodic table?
The periodic table of the elements is filled mostly with metal elements.
What is the periodic table filled with?
It is filled with the names (or chemical symbols) of elements.
What elements are the transition elements?
the transition elements are those elements having a partially filled d or f subshell in any common oxidation state.
In a Bohr diagram how many electrons are in each shell?
There are 4 electron sub-shells: s, p, d, and f. These letters stand for sharp, principal, diffuse, and fundamental, but the names are not important. s subshells have 2 electons, while p subshells have 6, d subshells have 10, and f subshells have 14. There can be higher subshells, but these subshells require too much energy to fill and no element with a g subshell (the next subshell after f) has ever been synthesized. The first shell (i.e. the first period of the periodic table) has only s. Thus, the first shell has 2 electrons. The second shell has s and p subshells, so it has 2+6 or 8 electrons. The third shell has s, p, and d subshells. It ultimately has 18 electons. This can be misleading, however. The d subshell requires more energy to fill than the higher-shell s subshell. This is why the third period of the periodic table does not have a d section: the d electron subshell of the third Bohr shell does not fill until after the s subshell of the fourth Bohr shell has filled. Looking at the periodic table, you can see that the third period only has 8 electrons, while the 4th period has 18. The 18 electrons in the fourth period are the s subshell of the fourth shell, the d subshell of the 3rd shell, and the p subshell of the 4th shell. The fourth shell is similar to the third shell, but more extreme. The fourth shell has s, p, d, and f subshells, but the f subshell is not filled until two higher s shells have been filled. It does, however, fill out to 32 electrons in the 6th period of the periodic table. In the 6th period, the first period to have 32 electrons, there are 32 electrons, filling these subshells: s subshell of the 6th shell, f subshell of the 4th shell, d subshell of the 5th shell, and then the p subshell of the 6th shell. The fifth shell would ultimately fill out to a full 50 electrons and would do so in the 8th period of the periodic table. However, as previously noted, no substance has ever been found or generated with that many electrons. It would fill the s subshell of three shells above (i.e. shell 8) before it filled the g subshell of shell 5. No element in the 8th period has ever been synthesized, so a filled fifth Bohr shell has never been found. A good example for a Bohr diagram would be Astatine, which is in the 6th period. In the first shell of the Bohr diagram, you have 2 electrons (s subshell only). It is filled completely. In the second, you have 8 electrons (s and p subshells) and in the third you have 18 electrons (s, p, and d), and both shells are filled completely. In the fourth shell, you have 32 electrons (s, p, d, and f), and it is filled completely. In the fifth shell, you have 18 electrons. This is because only the s, p, and d subshells are filled. It would require too much energy to fill the f subshell of the 5th shell, so the electrons just go to the s, p, and d subshell of higher shells. The 6th shell has 7 electrons. The 2 electrons of the s subshell are filled first, and then 5 electrons go into the p shell.
Why was leaving spaces and gaps in the periodic table later vindicated?
Those gaps were later filled by elements discovered after the creation of the table, which justified the gaps being left for that purpose.
What group occupies the large middle section of the periodic table?
its d-block i.e. elements whose outermost electrons lie in d-subshell.
What is it meant by a transition element?
A transition element are those element who have a partially filled d or f subshell in any common oxidation state. It is also any set of metallic elements occupying a central block in the periodic table such as copper, iron, manganese, and chromium.
Why does the periodic table end with a noble gas?
because they have completely filled orbitals
