loses 2 electrons to achieve a noble gas configuration
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.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
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.
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.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
4 but it will need energy, so carbon gain 4 electrons to achieve a noble gas configuration.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
By transfer or sharing of electrons.
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.
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.
Oxygen needs to gain 2 electrons to achieve a noble gas configuration, as it has 6 valence electrons and wants a full valence shell of 8 electrons, like a noble gas.
Strontium, a group 2 element, will lose 2 electrons to attain a noble gas configuration because it will achieve a stable electron configuration similar to the nearest noble gas, which is krypton. Strontium has 38 electrons in its neutral state, while krypton has 36 electrons. By losing 2 electrons, Strontium becomes Sr2+, and its electron configuration is similar to krypton.
Calcium has to lose 2 electrons to form noble gas configuration.
