Extramarks - The Learning App - Metals
Metals are defined as the elements which form positive ions by the loss of electrons. Atoms of metals usually have 1, 2, or 3 electrons in their outermost shells. Metals are egorized on the basis of their characteristics into alkali metals, alkaline earth metals, Transition metals and Inner transition metals.
Calcium carbonate is used in medicine and agriculture. It is also used in flue gas desulfurization in fossil fuel power stations, production of toothpaste, ceramics/glazing appliions, purifiion of iron from iron ore, and to clean tarnish on silver. It is used in the

Why is potassium (K) is the most reactive metal of all …
Within the alkali metals family, reactivity increases with increasing atomic nuer. This makes Francium the most reactive, followed by cesium, rubidium, potassium, sodium and lithium.
Some of the Group 1 and 2 metals are amongst the most abundant: calcium, sodium, magnesium and potassium are the 5th to 8th most abundant metals respectively, though others like Lithium and Beryllium have very low abundances.

Filtration in the Café - Fresh Cup Magazine
For example, a column coated with sodium salt might interact with water heavy in calcium, trading two sodium (Na +) molecules for one calcium (Ca 2+) molecule; the resulting water is high in sodium but lower in calcium, reducing the chance of scale formation.
Potassium - Wikipedia
Potassium is the second least dense metal after lithium.It is a soft solid with a low melting point, and can be easily cut with a knife.Freshly cut potassium is silvery in appearance, but it begins to tarnish toward gray immediately on exposure to air. In a flame test, potassium and its compounds emit a lilac color with a emission wavelength of 766.5 nanometers.
