Understanding Electron Arrangement - Quiz 3

How many electrons in Ca(2+)?

Electrons can only orbit nuclei in fixed orbits with specific characteristic energy levels.

Ionisation of an atom is the process in which the subatomic particle, the [blank_start]electron[blank_end], is removed. The outermost particle will have the [blank_start]least[blank_end] binding energy, and so will be most [blank_start]easy[blank_end] to remove. As the particles are taken away, the energy increases, increasing the amount of energy required.

Insert a number, eg 1, 4, 26, 32. If no electrons, put in 0. How many electrons in each shell: Magnesium: 1st: [blank_start]2[blank_end] 2nd: [blank_start]8[blank_end] 3rd: [blank_start]2[blank_end] 4th: [blank_start]0[blank_end] 5th: [blank_start]0[blank_end]
