The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Krypton has the same electron arrangement as Sr2. Both have a total of 36 electrons arranged in outer shells with the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
K+ and argon have the same electron configuration
Krypton has the same electron configuration as phosphorus in a PCl3 molecule. Both have the electron configuration of [Ne] 3s^2 3p^3.
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
Krypton (Kr) has the same electron configuration as S2, which is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6.
Silicon has 4 valence electrons. No noble gases will have 4 valence electrons.
Krypton has the same electron arrangement as Sr2. Both have a total of 36 electrons arranged in outer shells with the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6.
The symbol for the noble gas used to represent the core electrons of zirconium is [Kr] (krypton). This notation indicates that the core electrons of zirconium are equivalent to the electron configuration of krypton, which is a noble gas with a filled electron shell, so Zr would have the same core electron configuration as Kr.
The noble gas element strontium (Sr) has the electron configuration of [Kr]5s^2. This means that it has the same electron configuration as krypton (Kr), with two electrons in its outermost shell (5s).
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
An ion of bromine has the electron shell arrangement of 2, 8, 18, 7. Therefore, an atom that has the same electron shell arrangement would be one that has 35 electrons, such as the element bromine itself before it becomes an ion with a charge of -1.
