Questions
- In the nucleus is where the mass is found.
- The electron cloud has the largest volume.
- The nucleus is positive.
- The electron cloud is negatively charged.
- The overall charge of the nucleus is positive and the electron cloud is negative which cancel each other out and keeps the atom stable and together.
- The electron to proton ratio is the same in both (1:1). They both have all the subatomic particles.
- Hydrogen has one of everything. Hydrogen has two of everything.
