Calcium was discovered by Sir Humphry Davy in 1808, and barium was discovered by Carl Wilhelm Scheele in 1774.
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.
Beryllium, magnesium, calcium, strontium, barium, and radium.
The balanced equation for the reaction between barium sulfate (BaSO4) and calcium chloride (CaCl2) is BaSO4 + CaCl2 -> BaCl2 + CaSO4. This reaction forms barium chloride (BaCl2) and calcium sulfate (CaSO4) as products.
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
Calcium is a member of group 2, whose elements are beryllium, magnesium, calcium, strontium, barium and the radioactive radium.
When barium sulfate is mixed with calcium chloride, a double displacement reaction occurs where barium chloride and calcium sulfate are formed. Barium chloride is soluble in water, while calcium sulfate is not, so a solid precipitate of calcium sulfate will form.
All discovered by Humphrey Davy through electrolysis
It is not known what country barium was discovered in but it was discovered by German Carl Wilhelm Scheele in 1774. Barium is an alkaline metal.
Calcium and barium have different reactivities. Barium is more reactive than calcium because it has a greater tendency to lose electrons and form positive ions in chemical reactions. Calcium is a moderately reactive metal that readily forms compounds with oxygen and water, but it is not as reactive as barium.

Barium.
In 1808 it was shown that this substance was not an element. It starts with L and ends in e, so it cant be Barium.
Barium was discovered by Carl Wilhelm Scheele in 1774.
No, they do not.
No. Barium and magnesium and calcium are in group 2A but potassium is in group 1A.
Barium hydroxide and calcium hydroxide will not react with each other as they are both strong bases and do not undergo neutralization reactions.
No, Iron was known to man since ancient times... but magnesium was discovered in 1808 by Sir Humphrey Davy.
