part iii: isotopes 12. play with the simulation to determine (make sure all boxes are clicked): a) which particles affect the stability of the atom? ____________ b) which particles do not affect the stability of the atom? ____________ 13. what are the names of the stable forms of oxygen? a) oxygen - 16 b) oxygen - __ c) oxygen - __ d) list all of the things that are the same about these atoms (ignore the electrons). e) list all of the things that are different about these atoms (ignore the electrons). 14. the atoms in the previous question are isotopes of each other. based on this information, list the requirements for two atoms to be isotopes of each other. 15. test your understanding of isotopes by examining the relationships between the pairs of atoms listed below: | atom 1 | atom 2 | relationship between atom 1 and atom 2 | | ---- | ---- | ---- | | $_{6}^{12}c$ | $_{6}^{13}c$ | $square$ isotopes
$square$ same atom, not isotopes of each other
$square$ different element | b) each representation (symbol and name) in the table above provides information about the atom. describe the similarities and differences between the symbol and name representations. | symbol | name | | ---- | ---- | | $_{6}^{12}c^{ + 1}$ | carbon - 12 ion | | $_{9}^{18}f$ | | | $_{5}^{11}b$ | |

Question

Accepted Answer

# Explanation:
## Step1: Determine particles affecting atom stability
Protons and neutrons in the nucleus affect stability as they are involved in nuclear - forces.
Answer: Protons and neutrons
## Step2: Determine particles not affecting atom stability
Electrons are in the electron - cloud outside the nucleus and do not directly affect nuclear stability.
Answer: Electrons
## Step3: Identify stable forms of oxygen
The stable forms of oxygen are Oxygen - 16, Oxygen - 17, and Oxygen - 18.
Answer: 17; 18
## Step4: List similarities of oxygen isotopes (ignoring electrons)
They have the same number of protons (atomic number = 8), same number of electrons (when neutral), and same chemical properties.
Answer: Same number of protons; same chemical properties
## Step5: List differences of oxygen isotopes (ignoring electrons)
They have different numbers of neutrons and different mass numbers.
Answer: Different number of neutrons; different mass numbers
## Step6: List requirements for isotopes
Isotopes of an element have the same atomic number (same number of protons) but different mass numbers (different number of neutrons).
Answer: Same atomic number; different mass numbers
## Step7: Determine relationship between carbon atoms
$^{12}_{6}C$ and $^{13}_{6}C$ have the same atomic number (6) but different mass numbers (12 and 13), so they are isotopes.
Answer: Isotopes
