Accepted Answer

# Brief Explanations:
The text explains the process of charge separation in clouds (heavier water droplets become negatively charged, lighter ice crystals positively charged) leading to lightning. It also details electron movement during a lightning strike (about $1\times10^{20}$ electrons moving over $0.1 - 0.2$ seconds). For atoms, gaining electrons makes them negatively charged (as electrons are negatively charged particles), losing electrons makes them positively charged (protons in the nucleus are positively charged, and with fewer electrons, the positive charge dominates). Electrons cause static electricity (charge imbalance) and lightning (large - scale electron movement to balance charge).
# Answer:
- From the Findings section: Charge separation in clouds (negative at bottom, positive at top), electron count in lightning ($1\times10^{20}$), time of electron movement ($\sim0.2$ s). Different from Background (general concepts) and Research Methods (how data was collected) as it's specific results.
- a. Gaining electrons makes an atom's charge negative.
- b. Losing electrons makes an atom's charge positive.
- Electrons cause static electricity (charge imbalance) and lightning (massive electron movement to balance charge).
