Calcium is classified as an alkaline earth metal that is a bit hard and is silvery white in color. Its melting point is around 839 +/-2 degrees C and boiling point is around 1484 degrees C. Its specifiion for gravity is at 1.55 or is equivalent to twenty degrees C, and its valence is two.

hydrated. But the other alkali metal ions are comparatively big in size. They have therefore, lesser tendency to get hydrated. These salts are usually anhydrous. 7. Beryllium and magnesium do not give colour to flame whereas other alkaline earth metals do so
2003/3/19· Chemistry of the Group 1 Elements - Li, Na, K, Rb, Cs, Fr, from the edited h2g2, the Unconventional Guide to Life, the Universe and Everything Sodium and potassium are the most abundant Group 1 elements on the Earth, and can be found in rock salt deposits
Of the alkaline earth metals calcium and magnesium rank fifth and sixth in abundance respectively in the earth’s crust. Strontium and barium have much lower abundances. Beryllium is rare and radium is the rarest of all comprising only 10 -10 per cent of igneous rocks (Table 10.2, page 299).
Would you expect strontium to be, chemically, more similar to calcium or rubidium and WHY? What are the coinage elements? What is the heaviest noble gas? What is the heaviest alkaline earth metal? In going from top to bottom of any group, each element
classifiion metal belongs to the Alkaline earth metals family orgin name is calcis (lime) latin Discoverd by Sir Humphrey Davy (England) in 1808 I hope this helps someone who really needs it. All these facts are true. I used them for a project and made a A+
2019/9/29· Calcium is one of the alkaline earth metals. It darkens or oxidizes in air. It is the 5th most abundant element in the body and the most abundant metal. Scandium - Element 21 These are samples of high purity scandium metal.
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).They are harder and less reactive than the alkali metals of Group 1A. The name comes from

2012/5/20· Place in order of reactivity: potassium, sodium, * Relate the method of extraction of a metal calcium, magnesium, zinc, iron, hydrogen and from its ore to its position in the reactivity copper, by reference to the reactions, if any, of series.
A Group Brain Teaser: Which of the following words doesn''t belong: HELIUM, ARGON, CALCIUM, NEON, RADON :: Difficulty:1/4 Group These brain teasers rely on your ability to recognize groups of common attributes. For each of these puzzles you''ll need to figure
2020/8/4· This page explores the trends in some atomic and physical properties of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties. Even if
Reactions of alkaline earth metals (Mg & Ca) with hydrochloric acid (HCl) Magnesium and calcium react readily with dilute hydrochloric acid to form hydrogen gas and a water soluble metal salt. Like group 1, one observes an increase in reactivity down the group (i.e. Ca is more reactive than Mg)
The elements in the alkaline earth metals group; beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra), have two electrons in their outer electronic shell. Each element in this group has a tendency to lose two electron, to form a doubly charged positive ion, which has the stable electronic configuration of its neighbouring Nobel Gas element in the periodic
Among the alkaline earth metal hydroxides, calcium and magnesium are the strongest in terms of alkalinity in an aqueous solution. Calcium hydroxide is not quite as strong a base as potassium hydroxide or sodium hydroxide because it is only relatively soluble where the other two completely dissociate.
Both magnesium and calcium are in the second vertical column on the periodic chart. Like all Group 2 elements, magnesium and calcium are alkaline earth metals. They are both soft, silver-colored metals that react quickly with halogen gases such as fluorine
2020/7/17· Calcium is considered to be a metal. The general properties of calcium include limestone, chalk, gypsum, marble, and plaster. In terms of chemistry, calcium belongs to an element family called alkaline earth metals. Similar metals include magnesium and radium. Milk is a good source of calcium
2020/1/17· Magnesium is an alkaline earth metal, the eighth most abundant mineral found in the earth’s crust. Because of its ready solubility in water, magnesium is the third most abundant mineral in sea water, after sodium and chloride. In the human body, magnesium is

The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be 2+, Mg 2+, Ca 2+, and so on). These metals are less reactive than the neighboring alkali metal. Magnesium is less active than sodium; calcium is less active than potassium; and so on.
