The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
When an atom becomes an ion, it gains or loses electrons to achieve a full outer electron shell, resulting in a change in electron configuration. For example, a neutral sodium atom (1s2 2s2 2p6 3s1) loses one electron to become a sodium ion (1s2 2s2 2p6). The electron configuration of the ion reflects this change in the number of electrons.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
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 electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
It accepts one electron.
Argon has the same electron configuration as a potassium ion, as both species have 18 electrons with the electron configuration of [Ne]3s²3p⁶.
When an atom becomes an ion, it gains or loses electrons to achieve a full outer electron shell, resulting in a change in electron configuration. For example, a neutral sodium atom (1s2 2s2 2p6 3s1) loses one electron to become a sodium ion (1s2 2s2 2p6). The electron configuration of the ion reflects this change in the number of electrons.
If a sodium atom loses an electron to become a Na+ ion, its electron configuration will be the same as neon (1s22s22p6). Both sodium and neon have stable electron configurations.
The chloride ion (Cl-) has the same electron configuration as argon (1s2 2s2 2p6 3s2 3p6) because it has gained an electron compared to a neutral chlorine atom. The chlorine atom has an electron configuration of 1s2 2s2 2p6 3s2 3p5.
The fluoride ion has the same electron configuration as a neon atom. This is because fluoride has gained an extra electron compared to a neutral fluorine atom, resulting in a full valence shell with 8 electrons. Therefore, the electron configuration of a fluoride ion is 1s2 2s2 2p6.
No, the electron configuration for an ion is not always the same as that of its nearest noble gas. When an atom loses or gains electrons to form an ion, its electron configuration changes. For example, a sodium ion (Na⁺) has the electron configuration of [Ne], which is the same as neon, but a chloride ion (Cl⁻) also has the same configuration as argon ([Ar]). Thus, while some ions can have configurations similar to noble gases, this is not universally true for all ions.
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 electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
Electron configuration of radium:Ra: [Rn]7s2Ra(2+): 1s2.2s2.2p6.3s2.3p6.3d10.4s2.4p6.4d1o.4f14.5s2.5p6.5d10.6s2.6p6.
It accepts one electron.
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.
The Fluoride ion, neon atom, and sodium ion all have the same electron configuration and known as ISO-ELECTRONIC ions.
