State the number of electrons lost or gained when the following elements form
Ions:
Group 5A (15)
Express your answer as an integer
Group 5A elements have a valence electron configuration of 5s²5p³. To achieve a stable electron configuration, they tend to gain 3 electrons to fill their outermost shell. Therefore, the number of electrons gained when Group 5A elements form ions is 3.
Elements in Group 5A (15), also known as Group 15 or the Nitrogen group, typically gain 3 electrons when forming ions. Therefore, the number of electrons gained when these elements form ions is -3.
To determine the number of electrons lost or gained when Group 5A (15) elements form ions, we need to consider their electron configuration.
Group 5A elements have a valence electron configuration of ns²np³, where n represents the principle quantum number.
Elements in this group include Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).
When atoms in this group form ions, they tend to gain three electrons to achieve a stable outer electron configuration of the nearest noble gas.
Therefore, the number of electrons gained is 3.
