I am not really an alkali metal, but since I have
only 1 electron I behave like them.
What element am i?
The element you are describing is Hydrogen (H).
To determine the element, we need to consider the fact that you have only one electron, which classifies you as a Group 1 element on the periodic table. The Group 1 elements are known as alkali metals and have similar properties due to the presence of one valence electron.
Some examples of alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Considering your description, it is likely that you are sodium (Na) since it closely matches the characteristics you provided. Sodium has one valence electron, similar to your situation, and generally behaves like other alkali metals due to the presence of that single electron.
