He proposed the Law of Conservation of Matter, being the first to say that matter can not be created nor destroyed.
1. by making a atomic configuration
2.by making a table of shells of k.l.m.n....
that's all
The student was not successful.
Consider the standard reduction potentials.
Li⁺ + e⁻ ⇌ Li; E° = -3.04 V
2H₂O + 2e⁻ ⇌ H₂ + 2OH⁻; E° = -0.83 V
To reduce Li⁺ to Li, the student must apply 3.04 V.
However, it takes only 0.83 V to reduce water to hydrogen.
Thus, the student will get H₂ instead of Li.
