Calcium must lose 2 electrons and will become Ca2+. It will then have the electron configuration of Argon, a noble gas.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
Calcium (Ca) has 20 electrons and its electron configuration is [Ar] 4s². To attain a noble gas electron configuration, calcium needs to lose two electrons to achieve the stable electron configuration of argon ([Ar] 4s² 3d¹⁰).
Caesium (Cs) has 55 electrons, and it will need to lose 1 electron to achieve a noble gas electron configuration. This is because Cs is in Group 1 of the periodic table, so losing 1 electron will leave it with the same electron configuration as the noble gas element in the previous period (Xenon).
A sulfide ion (S2-) must gain two electrons to achieve a noble gas electron configuration, similar to that of a stable, inert gas such as argon. This transfer allows the sulfide ion to fill its valence shell with eight electrons, satisfying the octet rule.
Both a neon atom and a sodium ion have 10 electrons. Neon is a noble gas with a full valence shell, while a sodium ion has lost one electron to achieve a stable electron configuration.
Cesium (Cs) has one electron in its outermost shell, which is in the 6th energy level. To achieve a stable noble gas configuration, cesium must lose this single valence electron, resulting in a positively charged ion (Cs⁺). After losing this electron, cesium attains the electron configuration of xenon, a noble gas. Therefore, cesium must lose one electron to become a noble gas.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
It should loose 2 electrons to become a noble gas.
Calcium (Ca) has 20 electrons and its electron configuration is [Ar] 4s². To attain a noble gas electron configuration, calcium needs to lose two electrons to achieve the stable electron configuration of argon ([Ar] 4s² 3d¹⁰).
The noble gas electron configuration of an iron 3 ion (Fe3+) is [Ar]3d^5. This means that the ion has lost three electrons, leaving behind a 3+ charge, and the remaining electrons are arranged based on the electron configuration of argon.
Caesium (Cs) has 55 electrons, and it will need to lose 1 electron to achieve a noble gas electron configuration. This is because Cs is in Group 1 of the periodic table, so losing 1 electron will leave it with the same electron configuration as the noble gas element in the previous period (Xenon).
The noble gas electron configuration for Uranium (IV) ion (U^4+) is [Xe] 4f^14 5d^10. This means that the electrons from the noble gas Xenon are included, along with 14 electrons in the 4f orbital and 10 electrons in the 5d orbital for a total of 24 electrons.
Iodine, located in Group 17 of the periodic table, has 7 valence electrons. To achieve a noble gas electron configuration (like Xenon), it must gain 1 electron to fill its valence shell and attain stability.
No, Ni2+ does not have a noble gas configuration. A noble gas configuration is attained when an atom has a full valence shell of electrons, like the noble gases in Group 18 of the periodic table. Ni2+ has lost electrons to achieve a stable electron configuration but does not have a full valence shell like a noble gas.
Gallium's atomic number is 31 and has a positive 3 charge which means it has lost 3 electrons to form an ion Ga3+. it has 28 electrons Hope this helps
calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]
