How metallic and nonmetallic character is related to valency?
Metallic and nonmetallic character is closely related to the valency of elements. Metals typically have low valency (1-3) and tend to lose electrons easily, exhibiting metallic characteristics such as conductivity and malleability. In contrast, nonmetals usually have higher valencies (4-7) and tend to gain or share electrons, leading to their nonmetallic properties like poor conductivity and brittleness. As a general trend, elements with lower valency are more metallic, while those with higher valency are more nonmetallic.
What 3 steps did mendeleev took to organize the elements?
Mendeleev organized the elements by first arranging them in order of increasing atomic mass, which allowed him to identify patterns in their properties. He grouped elements with similar chemical properties into columns, forming what we now recognize as periods and groups in the periodic table. Additionally, Mendeleev left gaps for undiscovered elements, predicting their properties based on the trends he observed, which demonstrated the periodic nature of the elements.
What elements are in groups 3-4 of the periodic table?
Transition elements are present in group 3-4. These elements have different properties.
What is three ways the periodic table arranged?
The periodic table is arranged by atomic number, which increases from left to right and top to bottom. Elements are grouped together based on similar chemical properties, and are organized into periods (rows) and groups (columns) to show trends in physical and chemical properties.
