Is oxygen and calcium an ionic compound?
The ionic formula for calcium oxide is simply CaO. The Calcium ion is an Alkaline earth metal and wants to give up the 2 s orbital elections and become a +2 cation. Oxygen has six valence electrons and is looking to gain two electrons to complete the octet (8) electron count in the valence shell making it a -2 anion.
Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF2. It is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.
- Calcium nitrate
Names Chemical formula Ca(NO3)2 Molar mass 164.088 g/mol (anhydrous) 236.15 g/mol (tetrahydrate) Appearance colorless solid hygroscopic Density 2.504 g/cm3 (anhydrous) 1.896 g/cm3 (tetrahydrate)
- OXIDIZER that enhances the combustion of other substances. No occupational exposure limits have been established for Calcium Nitrate. However, it may pose a health risk. Always follow safe work practices.
- Mixing coffee grounds with wood ash, shredded leaves and lime creates a rich compost, one high in nitrogen that's easy for tomatoes to access. Using grounds to make compost is also a way of lessening their acidity, because in their raw, untreated form, coffee grounds may make the soil too acidic for plants to thrive.

- Calcium absorption is best when a person consumes no more than 500 mg at one time. So a person who takes 1,000 mg/day of calcium from supplements, for example, should split the dose rather than take it all at once. Calcium supplements may cause gas, bloating, and constipation in some people.
- Calcium D-glucarate is made by combining glucaric acid with calcium to make supplements that people use for medicine. Calcium D-glucarate is used for preventing breast, prostate, and colon cancer; and for removing cancer-causing agents, toxins, and steroid hormones from the body.
- Calcium is a chemical element with symbol Ca and atomic number 20. An alkaline earth metal, calcium is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air.
