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.
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.
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.
On the periodic chart, the element with 5 electrons in its 3d orbital can be quickly identified. Elements with partially filled d-orbitals are located in the middle section, the "transitional metals." 3d is the first d-orbital, so we look in the first row of the middle section. This section fills the orbital by one more electron per element, so the one with 5 electrons is the fifth from the left.... Manganese! Atomic number 25.
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.
p-block elements have partially filled p-subshell. It is not completely filled.
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.
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.
In zinc (Zn), which has an atomic number of 30, the electron configuration is [Ar] 3d² 4s². The 3d subshell is partially filled with 2 electrons, while the 4s subshell is fully filled with 2 electrons. Therefore, the partially filled subshell in zinc atoms is the 3d subshell.
The electron configuration Xe 6s² 4f⁵ corresponds to the element Promethium (Pm), which has the atomic number 61. This configuration indicates that the element has filled xenon core (Xe) plus two electrons in the 6s subshell and five electrons in the 4f subshell. Promethium is a rare, radioactive lanthanide metal.
The electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d⁹ corresponds to the element silver (Ag), which has an atomic number of 47. This configuration indicates that silver has a filled 4p subshell and a partially filled 4d subshell, characteristic of transition metals. Silver is known for its high conductivity and is commonly used in jewelry and electronics.
In the elements from scandium (Sc, atomic number 21) to zinc (Zn, atomic number 30), the d subshell is being filled by electrons. Specifically, these elements are part of the transition metals, where the 3d subshell is progressively filled. As you move from scandium to zinc, the number of electrons in the 3d subshell increases from 1 in scandium to 10 in zinc.
No, the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 4d¹04p⁵ is not valid because it incorrectly suggests that the 4d subshell is filled before the 4p subshell. In the correct order of filling, the 4p subshell would be filled after the 4s and 3d subshells, so the proper configuration for an element with atomic number 35 (bromine) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.
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.
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.
The ground state electron configuration of mercury (Hg), which has an atomic number of 80, is [Xe] 4f² 5d⁹ 6s². This configuration indicates that mercury has a filled xenon core, followed by two electrons in the 6s subshell, nine in the 5d subshell, and two in the 4f subshell.
Three completely filled orbitals.
The noble gas configuration of chromium (Cr), atomic number 24, is [Ar] 3d^5 4s^1. This configuration indicates that after the noble gas argon (Ar), chromium has five electrons in the 3d subshell and one electron in the 4s subshell. This specific arrangement is due to chromium's tendency to achieve a more stable half-filled d subshell.
