Chemistry
Element with an atomic number 19 will:
- Accept an electron & get oxidized
- Accept an electron & get reduced
- Lose an electron & get oxidized
- Lose an electron & get reduced
Answer
Lose an electron & get oxidized
Reason — The element with atomic number 19 has the electronic configuration is 2, 8, 8, 1. It has 1 valence electron. It tends to lose its 1 valence electron to achieve a stable noble gas configuration. The loss of electron is defined as oxidation.
