An atom with 1 valence electron 'needs' a full shell, so it can either gain 7 electrons or lose 1. Which is more likely to occur?
Question
An atom with 1 valence electron 'needs' a full shell, so it can either gain 7 electrons or lose 1. Which is more likely to occur?
Solution
An atom is more likely to lose 1 electron to achieve a full shell. This is because it requires less energy to lose one electron than to gain seven. This is particularly true for elements in Group 1 of the periodic table, such as hydrogen, lithium, and sodium, which all have one valence electron and tend to lose that electron in chemical reactions.

You travel to an alternate universe where the atomic orbits are different from those on Earth, but all other aspects of the atoms are the same. In this universe, you find that the first (lowest energy) shell is filled with three electrons and the second shell can hold a maximum of nine electrons. You discover an element Z that has five electrons in its atom. Q 2.6Suggest whether you would expect Z to be more likely to form a cation or an anion. Justify your opinion.
