Question
Explain what happens to caesium atoms and to oxygen atoms when caesium reactswith oxygen to produce caesium oxide.You should answer in terms of electrons.
Solution
When caesium reacts with oxygen to produce caesium oxide, there is a transfer of electrons between the atoms.
-
Caesium is in Group 1 of the periodic table, meaning it has one electron in its outermost shell. This electron is relatively loosely held, so caesium tends to lose this electron in order to achieve a stable electron configuration, similar to that of a noble gas.
-
Oxygen, on the other hand, is in Group 16 of the periodic table, meaning it has six electrons in its outermost shell. Oxygen needs two more electrons to achieve a stable electron configuration.
-
When caesium and oxygen react, each caesium atom donates its one outer electron to an oxygen atom. This results in the formation of caesium ions (Cs+) and oxide ions (O2-).
-
The caesium ions and oxide ions then attract each other due to their opposite charges, forming an ionic bond and resulting in the compound caesium oxide (Cs2O).
So, in summary, caesium atoms lose electrons and become positively charged ions, while oxygen atoms gain electrons and become negatively charged ions. This transfer and subsequent attraction of electrons is what forms the ionic compound caesium oxide.
