a. The atom’s first electron shell, which is innermost and closest to the nucleus, can hold **2** electrons.
b. The second shell can hold more; **8** electrons.
c. The third shell can hold 8 electrons in its lower subshell and up to a total of **18** electrons (when considering higher subshells as well).
Regarding the collaborative catch-up on atomic structure:
1. The atomic weight of oxygen is approximately **16 amu (atomic mass units)** (more precisely about 15.999), and its atomic number is **8**.
For a neutral atom of oxygen, it would have **8 protons** and **8 electrons**. The number of protons is equal to the atomic number (the defining characteristic of an element), and in a neutral atom, the number of electrons equals the number of protons.
b. The second shell can hold more; **8** electrons.
c. The third shell can hold 8 electrons in its lower subshell and up to a total of **18** electrons (when considering higher subshells as well).
