electrons / protons / neutrons
Isotopes are atoms with the same number of but different number of .
|
Which of the following are plausible isotopes of carbon?
|
stable / unstable / gamma / theta
Some isotopes are and can decay into other elements. Decay involves emitting radiation such as alpha, beta, and radiation.

Electrons, shells, and ionisation
absorb / emit / shells / ionisation / radiation / nearer / further
- Electrons orbit the nucleus at specific energy levels which are also called .
- The shells get progressively from the nucleus and increase in energy level.
- Electrons can electromagnetic radiation and jump to a higher energy level / shell. In these cases we say that the electron has become 'excited'.
- Excited electrons can later fall back to a lower energy level, and electromagnetic radiation in the process.
- Electrons can also absorb enough energy to leave the atom altogether, this is known as .
