What sub-shell is being filled by Silver?

Silver (Ag) has an atomic number of 47, and its electron configuration is [Kr] 4d¹⁰ 5s¹. The sub-shell being filled by silver is the 4d sub-shell, which is fully filled with 10 electrons. Additionally, the single electron in the 5s sub-shell contributes to its chemical properties.


How many electrons does a Mn have in the 3d sub-shell?

Manganese (Mn) has a total of 25 electrons, and its electron configuration is [Ar] 3d^5 4s^2. In the 3d sub-shell, manganese has 5 electrons.


Is any element there without p subshell in valence shell in p block elements?

He does not have a p sub-shell in the valent shell. Because He has the noble gas configuration it is included in the p block.


What is the configuration for chromium?

Chromium has atomic no. of 24. Its electronic configuration is 1s22s22p63s23p64s13d5 . It should be 4s23d4 but it is not because the half filled d-sub shell provides extra stability to chromium atom.


Why is 2d1 not possible?

A break down of 2d1:2 = the quantum energy level or electron shell denoted as 'n'd = the sub-shell of the energy level (known as a degenerate level)1 = the number of electrons occupying the sub-shell.Through extensive research by scientists, no known element has a d sub-shell in the second (n=2) energy level. In fact, the d sub-shell does not appear until the fourth period (fourth row).The first d sub-shell is known to be in the third energy level (therefore the first energy level with this sub-shell is 3d, but not 2d).Transition metals are the elements known to fill the d sub-shells. The first transition metal in the periodic table is scandium (Sc) with the electron configuration of [Ar]4s23d1.The reasons for the formation of sub-shell of d is beyond my knowledge and the scope of basic chemistry.


How many sub-shell are there in second shell?

The second shell of an atom has two sub-shells: the 2s and 2p sub-shells. The 2s sub-shell can hold a maximum of 2 electrons, while the 2p sub-shell can hold a maximum of 6 electrons, allowing the second shell to accommodate a total of 8 electrons.


How can you tell the doffermce between 2s subshell and 2p subshell?

You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.
