Question

1. the first battery electrified the world of science, increasing the speed of science and the ability to separate compounds. davy started to study that electric current. he gave very popular lectures, before turning back to his work. he wanted to know if you could use a bigger battery to break down compounds that were more difficult to break down. he wanted to break down caustic pot ash. he found glowing, shining globules that exploded and burnt with a bright flame. what element did he discover?
2. he did the same with caustic soda (lye) to discover which element?
3. somehow the particles of matter must be glued together to form particles. if electricity could separate them, is that what stuck them together in the first place? he found that elements were held together because opposites (attract / repel) ← chose one of the two options

Explanation:

1. When Humphry Davy electrolyzed caustic pot - ash (potassium hydroxide, KOH), he discovered potassium. Potassium is a highly reactive metal that burns with a bright flame when exposed to air.
2. When he electrolyzed caustic soda (sodium hydroxide, NaOH), he discovered sodium. Sodium is also a very reactive metal.
3. Opposite charges attract. In the context of chemical bonding, positive and negative ions are held together by electrostatic forces of attraction.

Answer:

1. Potassium
2. Sodium
3. attract
