(a) The element with electron configuration: 1s2 2s2 2p6 3s2 3p5; (b)A noble gaseswith f electrons; (c) a fifth-period element whose atoms have three unpaired pelectrons; (d) First row transition metals having one 4s electron.
Losing an electron cesium has a noble gas configuration.
No, an abbreviated electron configuration of Xe using noble gas notation would be [Kr] 5s2 4d10 5p6. This notation shows the electron configuration of xenon (Xe) using the electron configuration of the noble gas krypton (Kr) as a starting point.
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble-gas electron configuration, silver would need to lose one electron to achieve a stable electron configuration that resembles a noble gas configuration like argon.
chlorine would need only one electron to attain an octet structure.
The electron configuration of cesium in noble gas form would be [Xe] 6s^1. This indicates that cesium has the same electron configuration as the noble gas xenon in addition to one extra electron in the 6s orbital.
Losing an electron cesium has a noble gas configuration.
No, an abbreviated electron configuration of Xe using noble gas notation would be [Kr] 5s2 4d10 5p6. This notation shows the electron configuration of xenon (Xe) using the electron configuration of the noble gas krypton (Kr) as a starting point.
No, potassium does not have a noble gas electron configuration. The noble gas configuration for potassium would be [Ar] 4s¹, but instead, potassium has the electron configuration 1s² 2s² 2p^6 3s² 3p^6 4s¹.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble-gas electron configuration, silver would need to lose one electron to achieve a stable electron configuration that resembles a noble gas configuration like argon.
chlorine would need only one electron to attain an octet structure.
An element that would have to lose three electrons to achieve a noble gas electron configuration is aluminum (Al). Aluminum has 13 electrons, and if it loses three electrons, it would have the same electron configuration as neon (10 electrons), which is a noble gas.
The noble gas configuration for potassium is [Ar] 4s^1. To form a cation, potassium would lose its one valence electron, resulting in a 1+ ion. Therefore, the ion formed when potassium achieves a noble gas electron configuration is K^+.
Silver (Ag) has 47 electrons. To achieve a pseudo-noble gas electron configuration, silver would need to give up one electron to match the electron configuration of the noble gas, krypton (Kr), in which the outermost energy level is full. This would leave silver with 46 electrons.
To achieve noble gas configuration, Bromine must gain one electron. In doing so, it obtains the electron configuration of Krypton. It's new complete electron configuration would be: 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.
Sulfur must lose six electrons to attain noble gas electron configuration (in SO3, H2SO4 etc) but in most of the compounds it will exist as sulphides which is formed when sulphur will gain two electrons.
