The most likely products from the reaction between calcium carbonate (CaCO3) and sodium metal (Na) would be calcium oxide (CaO), sodium carbonate (Na2CO3), and elemental calcium (Ca) due to the displacement of sodium.
The most important factor in decreasing intracellular calcium ion concentration after contraction is the active transport of calcium ions out of the cell by the calcium ATPase pump located on the cell membrane. This pump helps in restoring the calcium ion concentration back to its baseline level, allowing the muscle to relax and prepare for the next contraction.
Potassium is the most active metal. It is highly reactive and can easily react with water to produce hydrogen gas and caustic potassium hydroxide.
The most active metal is francium (Fr). It is located farthest to the left and at the bottom. The most active nonmetal is fluorine (F). It is located at the top of Group 17 (the halogens).
Fluorine is the most active non-metal due to its high electronegativity, which allows it to readily gain an electron to achieve a stable electron configuration. Francium is the most active metal because it has the lowest ionization energy among all the elements, making it highly reactive and prone to losing an electron to form a positive ion.
Lithium is NOT the most active alkali metal. Francium is the most active but is available in such trace quantities and radioactive that for practical purposes it is Cesium that is considered most active.
Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.
It is an Alkaline Earth Metal

Calcium is the most chemically active alkaline earth metal because it has a relatively low ionization energy compared to its group counterparts, which allows it to easily lose its two valence electrons. This property makes calcium more reactive, particularly with water and acids, leading to the formation of hydroxides and salts. Additionally, its larger atomic size compared to beryllium and magnesium results in a weaker attraction between the nucleus and the valence electrons, further enhancing its reactivity.
There is no such thing. There are carbon atoms of varying properties, and isotopes. There is no such thing as an "human carbon atom."
Calcium is the most prevalent in the human body.
The number of grams in 9,0 moles of calcium metal is 360,7 g.
Francium is the most reactive metal.

Calcium is a very active element which forms innumerable compounds. The most familiar one is calcium carbonate, also known as limestone.
