Selenium, the element immediately below sulfur in the same column of a wide form Periodic Table. (The element immediately above sulfur in the same column, oxygen, is the lightest element in the column, and these lightest elements in a column of main group elements often have chemical properties somewhat different from all the other elements in the column. Sulfur, for example, has a much lower electronegativity than oxygen, while the difference between electronegativities of selenium and sulfur is much less.)
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
Se (Selenium)
sulfur
Lanthanides have properties similar to Cerium
any element in the same group as oxygenmainlysulfurselenium
The last answer here was wrong by the way. Oxygen and sulfur aren't alike.
This element is selenium.
The element that would have properties most similar to the new element would be an element that lies in the same group as the new element. Specifically, the element with the most similar properties will lie directly above or below that element in the group.
Se (Selenium)
sulfur
Lanthanides have properties similar to Cerium
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.

lanthanum and other lanthanides
Element A and element B are the most likely to have similar properties because they belong in the same family, because if you know an element's family you can tell the number of valance electrons and the elements they react with. In periods, the properties are not alike, they slowly change in a pattern.
The two elements that have the most similar chemical properties to arsenic are Phosphorus (P) and Antimony (Sb).
