To effectively compare the relative properties of elements, one would typically consider their position in the Periodic Table, including factors such as atomic number, electronegativity, ionization energy, and atomic radius. Elements in the same group often exhibit similar chemical behaviors due to having the same number of valence electrons, while those in the same period tend to show trends in properties like metallic character and reactivity. Additionally, comparing metals, nonmetals, and metalloids can further clarify differences in conductivity, malleability, and reactivity. Overall, these properties are interconnected and influenced by the electron configuration of the elements.
No, neodymium and uranium have different properties due to their different atomic structures and positions on the periodic table. Neodymium is a rare-earth metal with magnetic properties, while uranium is a radioactive heavy metal with nuclear properties.
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.

Two different samples of a pure substance would have the same physical properties, such as color, melting point, boiling point, and density. Their chemical properties, like reactivity and ability to form specific compounds, would also be identical. Variations in the samples' properties could indicate impurities present.
You would likely find five elements with very similar properties in the same group of the periodic table. For example, elements in Group 1 (alkali metals) like lithium, sodium, potassium, rubidium, and cesium share similar characteristics such as being soft, highly reactive metals with low melting points and easily losing electron to form cations.
Uranium and neodymium are very different chemical elements.
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
same number of valence electrons, so are their chemical properties more or less the same.
You would expect to find them in both.
The newest officially discovered elements are Ununquadiumand Ununhexium so, we'll focus on those.Ununquadium will be part of the Carbon series, so we would expect it to have properties similar to those elements (e.g. 4 electrons in the outer shell). The closest relation to it in that group would be Lead.Ununhexium will be part of the Oxygen series, so, again, we would expect it to have properties similar to those elements (e.g. 6 electrons in the outer shell). The closest relation to it in that group would be Polonium, which is also the first radioactive element.
No, neodymium and uranium have different properties due to their different atomic structures and positions on the periodic table. Neodymium is a rare-earth metal with magnetic properties, while uranium is a radioactive heavy metal with nuclear properties.
Rhenium is similar to technetium.
Metalloids are elements that have properties of both metals and nonmetals. They are located on the periodic table along the staircase between metals and nonmetals. Examples of metalloids include silicon, germanium, and arsenic.

Mendeleev arranged the known elements by increasing atomic mass and grouped elements with similar properties together. Gaps in the table indicated elements that were yet to be discovered. By observing the patterns in the properties of known elements within each group, Mendeleev was able to predict the properties of the undiscovered elements that would fill these gaps.
