All of the alkali metals, Group 1, have one valence electron. which of these would represent the oxidation number of the alkali
metals such as lithium and sodium
1 answer:
Answer:
+1
Explanation:
The oxidation state of the alkali metals such as lithium and sodium which belongs to the first group will be +1.
- For simple ions, the oxidation number is the charge they carry.
- Oxidation number is the formal charge assigned to an atom.
- Metals generally have a positive oxidation number which shows their readiness to lose electrons.
- In this regard, most alkali metals would lose one electron to form bonds with other substances.
- This way, the number of protons will be greater in them and leave a positive net charge.
