the answer is 6
The 2d sub energy level does not exist. The first shell to contain a d sub-shell is the third shell: the 3d sub-shell contains a maximum of 10 electrons, with two electrons in each of five different d orbitals.
The maximum number of electrons in a 'D' sublevel is 10
The letter designations for the first four sublevels and their maximum number of electrons are as follows: s sublevel: can hold a maximum of 2 electrons. p sublevel: can hold a maximum of 6 electrons. d sublevel: can hold a maximum of 10 electrons. f sublevel: can hold a maximum of 14 electrons.
The 4th shell has 4 sub-shells. These are 4s, 4p, 4d and 4f which can hold 2,6,10 and 14 electrons respectively. Adding these we get 32 which is the maximum number of electrons that can be accommodated in the 4th shell.
Ok, if you have Sapling h.w....the answer is... ions with 6d electrons..Fe2+, Ru2+, Os2+ ions with 10d electrons..Zn2+, Cd2+ the question is just asking...which element has d^6 and d^10 in its electronic configuration?

2 electrons.
A number of electrons.
The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)
The maximum number of electrons in a 'D' sublevel is 10
The letter designations for the first four sublevels and their maximum number of electrons are as follows: s sublevel: can hold a maximum of 2 electrons. p sublevel: can hold a maximum of 6 electrons. d sublevel: can hold a maximum of 10 electrons. f sublevel: can hold a maximum of 14 electrons.
The sub-level that contains a maximum of three pairs of electrons is the p sub-level. Each p sub-level can hold a maximum of six electrons, meaning it can accommodate up to three pairs of electrons.
== Answer== Generally, each sub-shell has its own energy. The sub-shells, listed in order of energy with the number of orbitals in that sub-shell, with the number of electrons each one occupies, are:1s: 1 orbital, 2 electrons2s: 1 orbital, 2 electrons2p: 3 orbitals, 6 electrons3s: 1 orbital, 2 electrons3p: 3 orbitals, 6 electrons4s: 1 orbital, 2 electrons3d: 5 orbitals, 10 electrons4p: 3 orbitals, 6 electronsetc.So, in the first four separate energy levels or sub-shell (1s, 2s, 2p, and 3s) there are 2 + 2+ 6 + 2 = 12 electrons. Note that in these first four sub-shells there are 6 orbitals (with 2 electrons each).
The 4th shell has 4 sub-shells. These are 4s, 4p, 4d and 4f which can hold 2,6,10 and 14 electrons respectively. Adding these we get 32 which is the maximum number of electrons that can be accommodated in the 4th shell.
The maximum number of s electrons that can exist in any one principal energy level is 2. This is due to the Pauli exclusion principle, which states that each electron in an atom must have a unique set of quantum numbers.
