K+ and argon have the same electron configuration
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
The electron configuration of a fluorine atom is 1s2 2s2 2p5. When fluorine gains an electron to form a fluoride ion, its electron configuration becomes 1s2 2s2 2p6, which is the same as that of a noble gas (neon). This gives the fluoride ion a stable, filled outer electron shell.
The negative ion F has the same electronic configuration as the positive ion Ne. This is because the negative ion F gains an electron to achieve a stable octet configuration, similar to the stable electronic configuration of the noble gas Ne.
Potassium can lose one electron from its outer shell to achieve a stable electron configuration similar to argon. Fluorine can gain one electron to fill its outer shell and attain a stable electron configuration like neon. In both cases, the atoms are trying to achieve a full valence shell and become stable like the nearest noble gas.
The noble gas configuration for selenium is [Ar] 3d10 4s2 4p4, which means it has the same electron configuration as argon, followed by 4d10 4p4 electrons.
I- ion (iodine ion and not iodine) and xenon will have the same number of electrons (54 electrons)
It accepts one electron.
Metals like sodium,potassium get noble gas configuration by losing electrons. Elements like nitrogen,oxygen get noble gas configuration by gaining electrons. Halogens get noble gas configuration by sharing electrons.
Generally (but not always) stable ions will have the same the electronic configuration as that of noble gases (completely filled valence shells / orbitals)
The ion formed when sodium achieves a noble-gas electronic configuration is Na+. This means that sodium has lost one electron to achieve the same electron configuration as neon, a noble gas, which has a stable electron configuration.
The electronic configuration of calcium is 1s2 2s2 2p6 3s2 3p6 4s2. In calcium hydroxide (Ca(OH)2), calcium loses its two outer electrons to form Ca2+ ion, which has the electronic configuration 1s2 2s2 2p6 3s2 3p6.
