Periodic table – Group 1 The alkali metals have a silvery, shiny surface when they are first cut. However, this goes dull very quickly as the metals reacts with the oxygen in the air. e.g. sodium + oxygen sodium oxide 4Na(s) + O2(g) 2Na2O(s) Lithium, sodium and pota...

The elements in group 0, the right most corner of the table, have stable electron structure and are the inert gasses. The elements in Group VIIA and VIA are deficient of one and two electrons, respectively, for a stable structure. The elements in Groups IA and IIA are one and two ...
The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 termed s-block elements. Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.
One of the early models of the periodic table arranged elements by atomic weight, which naturally grouped elements with similar properties together. 有种早期的元素周期表按原子量来排列元素,自然就将性质相似的元素放在一起了。 However, certain elements were outliers, and did not fit in their groups....
