Molecular ions are formed by passing
Correct answer: A. High energy trelecon beam
- A. High energy trelecon beam
- B. α-particle
- C. X-rays
- D. All of the above
Explanation
Molecular ions are formed by passing high-energy electrons through a sample .High-energy electrons can ionize molecules by knocking off electrons from them, resulting in the formation of molecular ions.This is the most common method and involves bombarding molecules with electrons having enough energy to knock out an electron from the molecule's orbital. This creates a positively charged molecular ion (cation).

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
