How many electrons would calcium have to lose or gain to have to have 8 valence electrons?

Calcium would need to lose 2 electrons to have 8 valence electrons. This is because calcium has 2 valence electrons in its outer shell, and by losing these 2 electrons, it can achieve a stable octet configuration like the noble gas argon.


How many electrons does nitrogen gain in order to achieve a noble gad electron configuration?

nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.

How many electrons does barium have to give up in order to achieve a noble gas electron 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.


How many electrons need to be removed from boron to form noble gases?

Boron must give up 3 electrons in order to achieve a noble-gas electron configuration.

How many electrons does silver have to gave up in order to achieve a pseudo-noble-gas electron configuration?

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.


Which of the following would have to lose three electrons in order to achieve a noble gas electron configuration?

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.


How many electrons does carbon need to gain in order to obtain a noble-gas electron configuration?

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.


How many electrons does phosphorus have to gain in order 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.


How many electrons does nitrogen have to gain in order to achieve noble gas electron configuration?

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.
