Group one elements are the alkali metals.
The elements in Group 1 have one valence electron in their outermost s orbital.
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
The group A elements together comprise one family called as 'Alkali metals'.
Group 1 elements are alkali metals. Group-18 elements are inert in nature.
In group 3A elements, or elements in group 13, have only one unpaired electrons.
Group 1 elements are metallic in nature. They have 1 electron in their outermost octet.
Alkali is a group of elements, not just one specific elements. Alkali metals are Group 1A elements starting with Hydrogen then lithium and so on.
An outer electron shell with only one electron.
The elements in this group are called Alkali Metals.
alkali metals
Elements are just one type of atom. An element is a group of atoms of one type.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
