Calcium - Simple English Wikipedia, the free encyclopedia

Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is

In this experiment, a strip of metal is added to a solution of a compound of another metal. A more reactive metal displaces (pushes out) a less reactive metal from its compound. In carrying out the experiment, students investigate competition reactions of metals and arrive at a reactivity series of the four metals they use.

Activity of Metals - Purdue University

We can decide which element should lose an electron by comparing the first ionization energy for potassium (418.8 kJ/mol) with that for hydrogen (1312.0 kJ/mol). Potassium is much more likely to lose an electron in this reaction, which means that hydrogen gains an electron to form K + and H - ions.

Carbonate - Wikipedia

Chemical properties Metal carbonates generally decompose on heating, liberating carbon dioxide from the long term carbon cycle to the short term carbon cycle and leaving behind an oxide of the metal. This process is called calcination, after calx, the Latin name of quicklime or calcium oxide, CaO, which is obtained by roasting limestone in a lime kiln.
