* Answer: Nitrogen.
* Hint: Look at Atomic Number 7 on the Periodic Table.
💡 Hint: Look at Atomic Number 7 on the Periodic Table.
Where exactly is the proton located within the structure of the atom?
* Answer: In the nucleus (the dense central core).
* Hint: It lives in the "heart" of the atom along with the neutrons.

What does the letter "Z" represent in chemistry?
* Type: mcq
* Options: A) Atomic Mass, B) Number of Neutrons, C) Atomic Number (Number of Protons), D) Total number of particles
* Correct Answer: C
* Explanation: Z is the standard scientific notation for the Atomic Number.
💡 Hint: No hint provided
True or False: Two different elements can have the same number of protons.
* Type: boolean
* Options: True, False
* Correct Answer: False
* Explanation: The number of protons is unique to each element. If the number of protons changes, the element's identity changes.

The Identity Crisis: A mysterious sample contains atoms with 26 protons. A chemical reaction occurs that causes these atoms to lose 2 electrons.
* Task A: Identify the element.
* Task B: State the new number of protons after the reaction.
* Solution:
* Task A: The element is Iron (Fe).
* Task B: The number of protons remains 26. Chemical reactions do not change the number of protons in the nucleus!
- Hint: "P" is for Proton, "P" is for Permanent (in chemical changes).
💡 Hint: "P" is for Proton, "P" is for Permanent (in chemical changes).
Isotope Investigation: You have two atoms. Atom A has 6 protons and 6 neutrons. Atom B has 6 protons and 8 neutrons. Are they the same element?
* Solution: Yes, they are both Carbon. Because they both have 6 protons, they have the same Atomic Number (). The difference in neutrons simply makes them different isotopes of the same element.
* Hint: If the proton count matches, the name matches.
💡 Hint: If the proton count matches, the name matches.
