Because they both have a different number of valence electrons in their outer shells, and that is what determines the properties of the element.
There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
Sulfur and oxygen will form polar covalent bond
a) nitrogen b) fluorine c) oxide iond) nitride ion e) sulfurOut of these options, the correct answer is e) sulfur. Sulfur is the chemical species that would be expected to have a properties most similar to oxygen.
any element in the same group as oxygenmainlysulfurselenium
Sulfur is in group 16. Other members are oxygen, selenium, tellurium and polonium and in some respects their chemistry is similar. The elemnt most like sulfur is selenium and to a lesser extent tellurium. Polonium is a metal, and oxygen has a high electronegativity which has a major effect on the chemistry
Silicon.

Each chemical element has specific chemical and physical properties.
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
Elements in a same group have same number of valence electrons and hence similar physical and chemical properties.
Elements showing properties similar to oxygen would be those that are found in the same group as oxygen (group 6A, or 16). Those would be sulfur (S), and selenium (Se)
Because they both have a different number of valence electrons in their outer shells, and that is what determines the properties of the element.
