∙ 9y agoThis is not an entirely objective question, but many would consider any two lanthanide metals to meet this test. The two heaviest two elements in any wide-form periodic table column would also be good candidates, as would zirconium and hafnium, because the lanthanide contraction result in their being almost the same size even though one of them is from a higher period than the other. An objective answer would require specifying some specific chemical property with the least quantitative difference between two elements.

∙ 9y agoThe elements in the same group on the Periodic Table tend to have similar chemical properties. For example, lithium (Li) and sodium (Na) in Group 1 have similarities due to their tendency to lose one electron to achieve a stable electron configuration. Another example is chlorine (Cl) and bromine (Br) in Group 17, which both tend to gain one electron to achieve a stable configuration.

∙ 12y agoAny two members of an inner transition metal period have very similar chemical properties. Aside from this, zirconium and hafnium are probably most similar.
Aluminum and silicon are elements that likely have physical and chemical properties most similar to boron. They are in the same group as boron on the periodic table and share some similar characteristics in terms of reactivity and bonding.
Elements in the same group of the periodic table have the most similar chemical properties. For example, elements in Group 1 (such as lithium, sodium, potassium) or Group 17 (fluorine, chlorine, bromine) will have similar properties due to their shared number of valence electrons and outer electron configuration.
Praseodymium (Pr) is an element in the periodic table that has properties most similar to cerium (Ce). Both elements are lanthanides and share similar chemical properties, including their reactivity and oxidation states.
Bromine and iodine have properties most similar to chlorine since they all belong to the halogen group on the periodic table. They share similar chemical reactivity, forming similar compounds and exhibiting comparable physical properties.
Rubidium and francium would have properties most similar to cesium due to their locations near cesium on the periodic table. They share similar chemical reactivity and physical properties such as low melting and boiling points, softness, and high reactivity with water.
The chemical properties of calcium are most similar to the chemical properties of magnesium and strontium, as they all belong to the same group in the periodic table (Group 2 or alkaline earth metals). These elements share similar reactivity, ionization tendencies, and ability to form ionic compounds with similar characteristics.

Aluminum and silicon are elements that likely have physical and chemical properties most similar to boron. They are in the same group as boron on the periodic table and share some similar characteristics in terms of reactivity and bonding.
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.
Elements in the same group of the periodic table have the most similar chemical properties. For example, elements in Group 1 (such as lithium, sodium, potassium) or Group 17 (fluorine, chlorine, bromine) will have similar properties due to their shared number of valence electrons and outer electron configuration.
Mendeleev listed the elements in order of increasing atomic weight and grouped elements with similar properties together. He left gaps for undiscovered elements and predicted their properties.
The pair of elements with the most similar chemical properties are lithium (Li) and sodium (Na). They belong to the same group in the periodic table (Group 1) and exhibit similar reactivity and chemical behavior due to having one valence electron.
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.
