Want this question answered?
Ca^(2+) is the Calcium cation .
CaCO3 also known as limestone.
Ca 2+ ( calcium ions ) are stored in the smooth endoplasmic reticulum.
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
Calcium donates two electrons (charged -2) in reaction with a nonmetal. Substracting this from the zero (of the non-charged element) it leaves the +2 charge of the ion Ca2+Ca --> Ca2+ + 2e-
Ca2 is basically two Ca's so it's larger (the plus doesn't compensate)
Ca(NO2)2
No, Ca2+ has 2 electrons LESS than Ca
If you mean Ca(OH)2(s) --> Ca2+(aq) + 2OH-(aq) this is the equation for the dissolving of calcium hydroxide in water.
CaCO3 also known as limestone.
Ca 2+ ( calcium ions ) are stored in the smooth endoplasmic reticulum.
The cation Ca(2+) exist in many compounds, for example in salts.
No. elemental calcium is Ca. The calcium ion is Ca2+
Ca2+
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.
Ca2+ + 2 I- --> CaI2
Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.
