The elements are also grouped in the periodic table into other elements with the same valence electrons. Some of the groups of elements in the periodic table are Alkali metals, Alkali or Alkaline Earth metals, Halogens, and Noble Gases.

Alkali Metals: Alkali metals are metals that can be found in Group 1A (Column 1; aside from hydrogen) on the Periodic Table of the Elements. They make up many salts in the earth's crust and have found a myriad of uses in modern society. The natural abundance in order is sodium, potas...
So what? Atoms in a certain group (column) tend to have similar properties. So, for example, the red column on the right contains the Noble Gases (helium, neon, argon, krypton, and so on), which are relatively unreactive. The pink column on the left contains the alkali metals (lithium...
Feldspar is a group of minerals that are aluminosilicates of the alkali metals potassium, sodium, and calcium. The most common color of feldspar is white to buff, but the color can be blue, green, gray, pink, buff, or white, depending on the trace impurities present. Feldspar is ...
Which elements in the periodic table are referred to alkali metals? Which element is a metalloid? (a) iron (b) silicon (c) sodium (d) cadmium. What are the characteristics of metalloids? On the periodic table, what are elements from the 7A(17) group called?
•While the word "alkaline" means "basic," "alkali" and "base" are not synonymous. An alkali, in fact, is one of a specific group of elements on the periodic table, as you'll soon learn. So be aware of the alkali vs. alkaline distinction. ...

What is the most metallic element? What is the heaviest alkali metal? What are the heavy metals on the periodic table? What is the heaviest alkaline Earth metal? What metal expands the most when heated? Is promethium the strongest metal?
Properties of the Alkaline Earth Metals The alkaline earths possess many of the characteristic properties ofmetals. Alkaline earths have low electron affinities and lowelectronegativities. As with thealkali metals, the properties depend on the ease with which electrons are lost. The alkaline earths ha...
