How many valence electrons do calcium have? From the electronic configuration we know that the outermost shell of Ca is the fourth shell and the number of electrons in that shell is the valence electrons. Here there are two valence electrons in the outermost shell. So the number of valence electrons in Ca is 2.
Does calcium have 1 valence electrons? Calcium has 2 valence electrons. You can see that there are 2 electrons in the outer energy level and these are the valence electrons.

How are calcium channel blockers used to treat patients?
Calcium channel blockers are medications used to lower blood pressure. They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to squeeze (contract) more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.
How much calcium is allowed in drinking water?
Hardness is most commonly expressed as milligrams of calcium carbonate equivalent per litre. Water containing calcium carbonate at concentrations below 60 mg/l is generally considered as soft; 60–120 mg/l, moderately hard; 120–180 mg/l, hard; and more than 180 mg/l, very hard (McGowan, 2000).
Is the fluoride in calcium carbonate good for my teeth?
Conclusion: Fluoride delivered from calcium carbonate-based SMFP toothpastes is an effective means of reducing caries. Further, calcium carbonate may confer additional benefits through elevation of oral calcium levels and neutralisation of plaque-acids.
