- True
- False
Show hintHide hint
Recall the charges of the different subatomic particles.
Question 5.
An element has an atomic number of 12. Determine its atomic mass if it has 6 neutrons and provide its electron configuration.
Show hintHide hint
Use the atomic number and neutrons to find the atomic mass, then distribute electrons based on the 2n² rule.
Question 6.
If an atom contains 5 electrons, how would you write its electron configuration and determine its valency?
Show hintHide hint
Distribute the 5 electrons according to the shell rules, then calculate the valency.
