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
Alkaline earth metal definition is - any of the divalent strongly basic metals of group II of the periodic table comprising beryllium, magnesium, calcium, strontium, barium, and
(a) noble gas; (b) chalcogen; (c) alkaline earth metal; (d) alkali metal In studying the periodic table, you might have noticed something about the atomic masses of some of the elements. Element 43 (technetium), element 61 (promethium), and most of the elements with atomic nuer 84 (polonium) and higher have their atomic mass given in square brackets.

2020/8/18· This page describes and explains three examples from beryllium chemistry where it behaves differently from the rest of Group 2. In fact, there are several similarities between beryllium and aluminium in Group 3. This is known as a diagonal relationship and is …
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
Calcium was first isolated by Sir Humphry Davy in 1808 in London. In a lecture to the Royal Society in June 1808, Davy described his experiments that year, which produced tiny amounts of metal, at best. He could not find any way to produce more calcium (3)
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
The alkaline earth metals have much higher melting points than the alkali metals: beryllium melts at 1287ºC, magnesium at 649ºC, calcium at 839ºC, strontium at 768ºC, barium at 727ºC, and radium at 700ºC. They are harder metals than the Group 1A

Calcium, Ca, is a soft, gray, nontoxic alkaline Earth metal. Although pure calcium doesn’t exist in nature, calcium compounds are very common in Earth’s crust and in sea water. Calcium is also the most abundant metal in the human body, occurring as calcium
The Periodic Table 38 B The Alkaline Earth Metals They are called alkaline because like alkali metals, they also react with water to form bases, but the bases are like mud or earth in that they do not dissolve well in water. 1. Physical Properties If the alkali metal
