chlorine would need only one electron to attain an octet structure.
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
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.
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.
Carbon needs to gain four electrons in order to obtain a noble gas electron configuration, similar to that of neon. This will result in a full valence shell with eight electrons, fulfilling the octet rule.
Nitrogen needs to gain 3 electrons to achieve noble gas electron configuration, similar to the nearest noble gas, which is neon. By gaining 3 electrons, nitrogen would have a full outer shell of 8 electrons, making it more stable.
Calcium will lose two electrons to gain the noble gas configuration of Argon.
nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
loses 2 electrons to achieve a noble gas configuration
Barium has 2 electrons in its outer shell. In order to achieve a noble gas electron configuration it needs to lose these 2 electrons. This will leave it with the same electron configuration as Xenon, a noble gas.
Boron must give up 3 electrons in order to achieve a noble-gas electron configuration.
Two.
Nitrogen has to gain three 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.

Carbon needs to gain four electrons in order to obtain a noble gas electron configuration, similar to that of neon. This will result in a full valence shell with eight electrons, fulfilling the octet rule.
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.
Nitrogen needs to gain 3 electrons to achieve noble gas electron configuration, similar to the nearest noble gas, which is neon. By gaining 3 electrons, nitrogen would have a full outer shell of 8 electrons, making it more stable.
