The figure shows the electronic configuration of an element. What do you obtain when it reacts with oxygen gas?

The atom contains one outer shell electron. Therefore, it is most likely that it’s a group one element. Hydrogen is the only nonmetal in group one. The rest are metals. Hydrogen only contains one electron. As this element contains more than one electron, it must be a metal.

The question asks, what do you obtain when it reacts with oxygen gas? The group one metals are very reactive and easily react with oxygen to form metal oxides. Oxides can be acidic or basic. Generally speaking, oxides become more acidic as you move from left to right across a period in the periodic table. As we are dealing with a group one metal, the oxide formed will be basic.

Therefore, when the element in the figure reacts with oxygen, you obtain a basic oxide.
