How does a barium atom become a barium ion with a #2^+# charge?
1 Answer
See explanation below.
Explanation:
Basically, an atom becomes an ion when it "steals" electrons from another atom or when another atom "steals" electrons from it. Barium becomes an ion with a
For instance, in the reaction represented below, solid barium reacts with hydrochloric acid to produce aqueous barium chloride and hydrogen gas:
In this redox reaction, barium starts as a neutral solid but becomes an aqueous ion with a
An atom is oxidized when it has one or more electrons stolen from it.
An atom is reduced when it steals one or more electrons from another atom.
