The ground state of and atom also means for it to be stable i.e. an equal number of protons to electrons i.e. the charge is balanced between these two.
In chemistry, an ion is unstable atom i.e. when there is atom that has one or more electrons than the number of protons or vice versa.
When talking gravitational spacetime, we have moved into the ultra-micro scales where we envision a quasi-physical existence i.e. there is motion and quanta at scales far beyond that of which humans or any creature of Universe will ever attain/observe.

The words physical/energy is a generalized terms that are inclusive of all fermions and bosons. Often times we people use the term energy the specifically mean EMRadiation( photonic ).
The term radio-activity has nothing to do with radio's ergo it is a left-over term from early days that still gets used loosely i.e.in more generalized terms.
The correct term is ionizing radiation i.e. forms of EMagnetic radiation or highly energetic fermions that cause atoms to become ions i.e. radiating particle that creates unstable atoms in their local area ex alpha( think plutonium ),
or that will pass through thinner layers of matter ex high speed beta/electron particles,
or that will pass thicker layers of matter ex x-rays( high-frequency photons ).

The Wikipedia article you linked is surprisingly clear and concise; good find. To add my own understanding to it, a normal crystal is a structure that is spatially periodic in its ground state. (For instance, a salt crystal consists of alternating sodium and chlorine ions with regular spacing.) Because of this, a crystal breaks spatial translation symmetry. The laws of physics generally don't care where you are, but if there's a crystal present to impose a lattice on space, your location relative to that lattice suddenly matters. We can easily generalize this concept to a "time crystal" that is temporally periodic, and so breaks time-translation symmetry. A swinging pendulum with no loss is a simple example of a temporally periodic system. The catch, though, is that a crystal has to be periodic in its ground state, and things like pendulums only oscillate once they've been excited. In fact, since a system's Hamiltonian drives its evolution in time, the ground state of any Hamiltonian should by definition not evolve in time, which would make a time crystal a contradiction. But recent literature is abuzz with smart people claiming otherwise, so I'd love to learn more.
