1. nucleus and electron

2. nucleus

3. Positively charged, negatively charged

4. zero

5. protons and electrons

6. Capacitor

Explanation:

1. nucleus and electron - Nucleus is the central part of atom which is positively charged

2. nucleus

3. Positively charged, negatively charged - Proton have +1 change and electron have -1 charge

4. zero - Neutrons are neutral in nature and hence have no charge

5. protons and electrons

6. Capacitor
