Verified step by step guidance1
Identify the number of electrons in the outermost shell for each atom depicted in the image. This is crucial because atoms tend to lose electrons from their outermost shell to achieve a stable electron configuration.
Examine atom A: It has one electron in its outermost shell. Atoms with a single electron in their outer shell are highly likely to lose that electron to achieve a stable, full outer shell.
Examine atom B: It has four electrons in its outermost shell. Atoms with half-filled outer shells are less likely to lose electrons compared to those with only one electron.
Examine atom C: It has three electrons in its outermost shell. Similar to atom B, it is less likely to lose electrons compared to an atom with only one electron in its outer shell.
Examine atom D: It has five electrons in its outermost shell. Atoms with more than half-filled outer shells are even less likely to lose electrons compared to those with fewer electrons.
