The electron configuration of an atom can be determined by identifying first the right order of the electron shells. The atomic number of Magnesium is 12 so we expect the electrons also sum up to 12. The condensed electron configuration is Ne 3s2. The complete configuration is 1s2 2s2 2p6 3s2.

Answer:
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.

I'm not so sure but I would say it could be an iconic bond!
Ionic compounds. because when in solid form they are held firmly in place therefore they cannot move to conduct electric current.
