It has been quite a long time since I last heard a ballad from K-artists.
Now I question the relevance of this post.
Since I mentioned about potassium earlier on, let's check K out.
- It's represented by a "K", a letter that doesn't appear in the element's name at all, but is based on the German word "Kalium".
- It is a very soft, light silvered colored metal that tarnishes quickly in air into a gray color.
- When it is burned, the flame is a light purple.
- Before the 19th century, it was thought that sodium and potassium were the same.
- It is an electrolyte, it helps conduct electricity in the body, as does sodium, calcium, chloride, and magnesium.
