Explanation:
Answer:
An atom of Bromine (Br) forms an ion and becomes Br⁻
Explanation:
- Atoms of elements gain or lose electron(s) to attain a stable configuration and form ions.
- When an atom gains electron(s) it forms a negatively charged ion called an anion.
- For example, Bromine is a halogen and its atom requires to gain one electron to attain stability and form a bromine ion (Br⁻).
- When an atom loses electron(s) it forms a positively charged ion called a cation.
- For instance, atoms of calcium(Ca) requires to lose two electrons to attain stability and form calcium ion (Ca²⁺).
Answer:
Molar Mass
Explanation:
Plz brainliest lemme know if wrong (:
Formula M1V1 =M2V2
1.5 * 100 = M2 *300
M2 = 1.5*100/300= 0.5.
Answer: the molarity is 0.5M.
