2.5 The Periodic Table – Chemistry
Element 43 (technetium), element 61 (promethium), and most of the elements with atomic nuer 84 (polonium) and higher have their atomic mass given in square brackets. This is done for elements that consist entirely of unstable, radioactive isotopes (you will learn more about radioactivity in the nuclear chemistry chapter).

Minerals and trace elements - British Nutrition Foundation
Calcium absorption is well controlled to match the needs of the body and so calcium balance can be maintained at a variety of different levels of calcium intake. Even at low levels of intake, there is evidence from the Gaia, for example, that calcium balance can be achieved.

This is commonly happens to barium, calcium, strontium, sodium and potassium. D) Matrix interferences due to differences between surface tension and viscosity of test solutions and standards. E) Broadening of a spectral line, which can occur due to a nuer of factors.
Elements and atoms (video) | Khan Academy
Or an atom of one element, how it could react, or how it could bond, or not bond, or be attracted, or repel, another atom of another element. So for example-- and we''ll learn a lot more about this in the future-- it is possible for another atom, someplace, to swipe away an electron from a carbon, just because, for whatever reason.

Diet, Nutrition, and Bone Health | The Journal of Nutrition …
Besides the amount of calcium in the diet, the absorption of dietary calcium in foods is also a critical factor in determining the availability of calcium for bone development and maintenance. There is therefore a need to identify food components and/or functional food ingredients that may positively influence calcium absorption to ensure that calcium bioavailability from foods can be
Pigments through the Ages - Spectroscopy
In general, the energy of the emitted x-ray for a particular element is independent of the chemistry of the material. For example, a calcium peak obtained from CaCO3, CaO, and CaCl2 will be in exactly the same spectral position for all three materials.

If the blood calcium is abnormal, measuring calcium and PTH together can help determine whether the parathyroid glands are functioning normally. Measuring urine calcium can help determine whether the kidneys are excreting the proper amount of calcium, and testing for vitamin D, phosphorus, and/or magnesium can help determine whether other deficiencies or excesses exist.
