Group 1 (metals) and Group 17 (non-metals).
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
Not clear: 'opposite' in respect to WHAT? NON-transition metals is not a defined group of elements.
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
The group of elements that share characteristics of metals and non metals is metalloids.
Group 18 of the Periodic Table has only non metals. Additionally, the stable elements of group 17 are also non metals.
Group 1 (for metals) and group 17 (for non metals).
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
The elements classified as non-metals are in right direction. They are present in group-15,16,17.
Definitely NON-Metals. , othjerwise known as the HALOGENS.
Group 17 elements are acceptors of electrons and group 1 elements ar donor of electrons.
non-metals
Metalloids
Group 7A are not metals.Alkaline earth metals refer to Group 2A.and group 7a is halogens which are non-metals
