How many electrons can be held in the first 4 energy levels?
== 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).
What sub-level contains a maximum of three pairs of 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.
How does this row reflect the subshells of the second shell?
The second period (row) on the periodic table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.
What is electron configuration and valence electrons?
Mostly they are s or p electron sub-orbitals in the same (outer) shell. In the transition metals sometimes one electron from a higher d orbital gets involved ( e.g. to reach the oxidation states Fe2+ and Fe3+).
Why magnesium belongs to s block?
Valent electrons are in the s sub shell. So it belongs to s block.
What sub shell each hold a certain number of?
A number of electrons.
What number of electrons that can be held in first orbit closest to the nucleus?
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)
How many electrons can the outer electron sub-shell usually hold?
8
What is the maximum number of electrons in the p sub shell?
the answer is 6
What are the maximum number of electrons that can be found in a 3s sub shell?
2

How many electrons can 3d hold?
There are a maximum of 10 electrons in the 3d sub-level.
What sub-level contains a maximum of three pairs of 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.
How many electrons in 2d xy?
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.
How many electron orbital shells does chlorine have?
Your question reveals a common confusion between orbitals and shells. Chlorine has three electron shells: the first, second and third. The first shell has just the one orbital, the 1s The second shell has two sub-shells, the 2s and the 2p. There are three p orbitals in the 2p sub-shell. Each orbital can hold two electrons, so there are eight electrons maximum in the second shell. The third shell likewise has two sub-shells, the 3s and the 3p, but the 3p is not completely filled, leaving room for one more electron. When chlorine gains this electron it will become a Cl- ion. This is summed up in the electron configuration 1s22s22p63s23p5.
How many electrons can fit in the fourth shell?
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.
How does this row reflect the subshells of the second shell?
The second period (row) on the periodic table consists of elements that are filling the 2nd energy level, from 2s1 in lithium to 2s22p6 in neon.
