The elements in group 1a to 8a called representative elements. This is due to the fact that they portray as wide array of chemical and physical properties.
transitional metal
transition elements
Sometimes these are called the "representative" elements.
They follow a pattern for valence electrons.
nonmetals
any in column 1a, 2a, 3a-8a
The goal of every element is to complete its outer shell of electrons through reacting with other elements. And atom's outer shell can hold up to eight electrons. The elements of group 8 already have 8 electrons, so they have no reason to react with other elements. Because they don't react they're called noble gasses.
Sometimes these are called the "representative" elements.
Yes In Groups 1A through 8A
They follow a pattern for valence electrons.
-melting/freezing point -boiling point -density -reactivity with acid -flammability -solubility
The block in the periodic table that consists of elements in groups 3A through 8A is the p-block.
groups 1a,2a,3a,4a,5a,6a,7a,8a : elements of each group generally have similar properties do to similar #s of valence e-s.
nonmetals
They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18 They are called noble gases or inert elements. Belong to group 8A or 18
I love you LUKE A.
- 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
Group 8a
The alkaline earth metals belong to group 2A elements. The alkali metals belong to group 1A elements. The halogens belong to group 7A elements. The noble gases belong to group 8A elements.
