The elements immediately above and below aluminum in the same column of a wide form periodic table: boron and gallium. As is usual for relatively light elements, aluminum is more like the element below it, gallium, than the one above it: Aluminum and gallium are both metals, while boron is a nonmetal. In compounds with oxyanions, however, boron is similar to aluminum compounds with oxyanions.
No, nitrogen and argon have different chemical properties. Nitrogen is a reactive diatomic nonmetal, while argon is a noble gas known for its inertness. Nitrogen tends to form compounds, while argon is largely unreactive.
Carbon would be the element that is most similar in chemical behavior to Silicon. Both carbon and silicon are in the same group on the periodic table (group 14) and share similar properties such as the ability to form covalent bonds and act as the central atom in complex molecules.

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.

Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
Uranium and neodymium are very different chemical elements.
I expect elements with similar properties in the periodic table to be most similar. For example, elements in the same group or period tend to have similar chemical characteristics due to their similar electron configurations.

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.
Cubic boron nitride would be expected to have properties similar to diamond, such as extreme hardness, high thermal conductivity, and excellent resistance to chemical corrosion. It is commonly used in cutting tools and abrasives due to its hardness and wear resistance.

Silicon (Si) would be expected to behave the most like carbon (C) due to their similar chemical properties and positions in the periodic table. Both elements can form strong covalent bonds, resulting in similar types of compounds and structures.
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.
