The outermost principle energy level for strontium is the 5th energy level.
Strontium hydroxide is base; the pH is over 7.
About twice as large, which is not that much at the first ionization level. Still, Magnesium has a slightly larger, one proton nucleus and one more electron in that valence level to add to the energy needed to pill the first electron out of it's orbital. Electron shielding may have something to do with this also as the other valance electron of this 2+ element may shield the pulled electron.
"Absorbed"
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.

Strontium. They both have two electrons in their outermost energy level, however since the electrons are farther from the nucleus in Strontium than in Calcium, Strontium is more readily able to shed these two electrons to achieve a more stable state with it's outermost energy level being complete (with 8 electrons).

Sr has two electrons in the highest occupied energy level
Strontium (Sr)
There are two electrons.

High-level-control fluoroscopy increases radiation dose to the patient.
It is potentially dangerous. The radiation level found in granite is enough to suppress the immune system, cause birth defects, and cause cancer. There are granite composite options which are not containing the level of radiation that is dangerous.
