Questions & Step-by-Step Solutions

Which of the following statements about hydrogen is true?
  • Step 1: Understand what hydrogen is. Hydrogen is the simplest and lightest element on the periodic table.
  • Step 2: Learn about cations. A cation is a positively charged ion, which means it has lost one or more electrons.
  • Step 3: Recognize that hydrogen can lose an electron. When hydrogen loses its only electron, it becomes a cation called H+.
  • Step 4: Know where this happens. This process often occurs in acid-base reactions, where acids release H+ ions.
  • Step 5: Conclude that the statement about hydrogen forming cations (H+) is true.
