Final answer:
The Build an Atom simulation is Done. The Build an Atom simulation has been opened and the process of building and assessing various atoms and ions has been completed.
The answer is option ⇒1
Step-by-step explanation:
The question involves using the Build an Atom simulation to construct and analyze different atoms and ions. For completing the tasks within the simulation, one needs to:
- Drag the appropriate number of protons, neutrons, and electrons to construct the required atom or ion.
- Identify the total number of each particle within the constructed species.
- Understand and apply the concepts of net charge and mass number.
- Predict the stability of an atom and validate it using the simulation feature.
For example, to create a neutral atom of Oxygen-16, one would drag 8 protons, 8 neutrons, and 8 electrons into the simulation template.
The isotope symbol would then be ¹⁶O since oxygen's atomic number is 8 and its mass number is 16.
If two more electrons are added to this atom, an ion with a -2 charge is created and the symbol for this ion is O²⁻.
The answer is option ⇒1
