Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the atomic structure?A neutral atom contains an equal number of protons and electrons
2. What is the neutralization reaction example?HCl (acid) + NaOH (base) → NaCl (salt) + H2O (water)
3. What does neutrality mean in science?Neutrality means that opposing forces, charges, or properties are exactly balanced, so there is no net effect.
4. How can we tell if a liquid is neutral?We can measure its pH. A pH of 7 shows equal amounts of hydrogen ions and hydroxide ions, meaning the liquid is neither acidic nor alkaline.

Homeostasis: The tendency of a system to maintain internal stability despite external changes.
Ion: An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
Buffer Solution: A solution that resists changes in pH when acid or alkali is added to it.
