What compound has the 2 plus ion that is the smallest with a filled d subshell and an anion that forms from the smallest halogen?
The compound with the 2+ ion that is the smallest with a filled d subshell is zinc (Zn^2+), and the anion that forms from the smallest halogen is fluoride (F^-). Therefore, the compound you are looking for is zinc fluoride (ZnF2).
What subshell is only partially filled in most transition metals?
In most transition metals, the d subshell is only partially filled. Transition metals typically have electrons in the d orbitals, which allows for a range of oxidation states and the formation of various compounds. The unique properties of these metals arise from the presence of these partially filled d orbitals.
A subshell contains eight electrons. Which subshell could it be?
A subshell that contains eight electrons is the 3d subshell. The d subshell can hold a maximum of 10 electrons, but in this case, with eight electrons, it is likely filled with a combination of spin-up and spin-down electrons. Other subshells, such as p (which can hold a maximum of 6 electrons) or s (which can hold a maximum of 2 electrons), cannot contain eight electrons.
Why configuration of 'Cr' is 3d5 4s1 and not 3d4 4s2 and 'Cu' is 3d10 4s1 and not 3d9 4s2?
The electron configurations of chromium (Cr) and copper (Cu) are exceptions to the expected order due to the stability gained from half-filled and fully filled d subshells. For chromium, having a half-filled 3d subshell (3d^5) provides extra stability, so one electron from the 4s subshell is promoted to the 3d subshell, resulting in 3d^5 4s^1. Similarly, for copper, a fully filled 3d subshell (3d^10) is more stable than having one more electron in the 4s subshell (3d^9 4s^2), leading to the configuration of 3d^10 4s^1.
What are three examples of elements with unpredictable electron configurations?
Chromium: Chromium typically forms a half-filled d5 configuration (4s1 3d5) instead of a fully-filled d4 configuration (4s2 3d4) due to the increased stability associated with the half-filled d orbital. Copper: Copper prefers to have a full d10 configuration (4s1 3d10) instead of a partially filled d9 configuration (4s2 3d9) as it increases stability. Silver: Silver can have an electron configuration of [Kr] 4d10 5s1 instead of the expected [Kr] 4d9 5s2 due to the stability associated with the fully-filled 4d orbital.
Subshell being filled by element with atomic number 47?
The element with atomic number 47 is silver (Ag). In its neutral state, the electron configuration of silver is [Kr] 4d^10 5s^1. This means the 4d subshell is being filled by the electrons of silver.
What electron subshell is being is being filled for the actinide series?
4f
What is the subshell being filled by argon?
Argon has completely filled M shell (or 3p orbital)
On the periodic table what tells you which subshell of an atom is being filled?
The period number on the periodic table tells you which energy level (shell) of an atom is being filled. The subshell within that energy level is determined by the block in which the element is located on the periodic table. For example, elements in the s-block fill the s subshell, elements in the p-block fill the p subshell, and so on.
Silver atom has completely filled d-orbitas in its ground state but how can you say that it is transition element?
According to definition, transition elements are those which have partially filled d-subshell in there elementary state or in one of the oxidation states. silver(z=47) can exhibit 2 oxidation state in which it has incompletely filled d-subshell (4d9). hence silver is regarded as trnsition element.
Which elements have a partially filled p subshell?
p-block elements have partially filled p-subshell. It is not completely filled.
What section of the periodic table is the 4f subshell being filled?
The 4f subshell is being filled in the lanthanide series of the periodic table, which are also known as the "rare earth elements." They are located in the f-block of the periodic table, filling the 4f subshell from atomic number 58 (Cerium) to 71 (Lutetium).
What are the exceptions for ionization energy in the periodic table?
Exceptions to the general trend of increasing ionization energy across a period in the periodic table occur when there is a half-filled or fully-filled subshell, which results in increased stability and lower ionization energy. This is known as the "half-filled and fully-filled subshell stability" rule.
What element of lowest atomic number contains a half filled d subshell at ground state?
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
Which subshell is represented by the actinides family?
The actinides family corresponds to the 5f subshell. This subshell can hold a maximum of 14 electrons and is located in the seventh period of the periodic table. The actinides are a series of elements with atomic numbers 89 to 103.
What compound has the 2 plus ion that is the smallest with a filled d subshell and an anion that forms from the smallest halogen?
The compound with the 2+ ion that is the smallest with a filled d subshell is zinc (Zn^2+), and the anion that forms from the smallest halogen is fluoride (F^-). Therefore, the compound you are looking for is zinc fluoride (ZnF2).
What is the ground state electron configuration for zinc?
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
