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.
How many valence electrons does zinc have in its outer shell?
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
What is the maximum number of sub-shells within each main shell of an atom?
The first principal energy level can hold up to 2 electrons, the second up to 8, the third up to 18 and fourth and others up to 32 each.
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.
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
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.
What is the maximum number of s electrons that can exist in any one principal energy level?
2. The S sub-shell has one orbital and an orbital can hold a max of 2 electrons.
What are the maximum number of electrons that can be found in a 3s sub shell?
2
What is the maximum number of electrons in the p sub shell?
the answer is 6
How many electrons can 3d hold?
There are a maximum of 10 electrons in the 3d sub-level.
How many electrons are indicated in 4p2?
4p2 means the there are 2 electrons in the 4p sub-shell. Till this sub-shell, the atom has 32 electrons
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+).
How many electrons are in the outermost shell of atom?
in the outer shell there is only aloud it be 8 electrons. Really it depends on the Element because metals have 4 or less Electrons in the outer ring. But nonmetals have 8 or less. So in order to know how many electrons there are you have to find out which Element you are wanting to know about.
Why magnesium belongs to s block?
Valent electrons are in the s sub shell. So it belongs to s block.
