Sulfur belongs to Group 16 (VIA) of the periodic table, also known as the chalcogens. Elements in the same group share similar chemical properties due to having the same number of valence electrons (electrons in the outermost shell).

Therefore, elements with similar properties to sulfur are:

* Oxygen (O)

* Selenium (Se)

* Tellurium (Te)

* Polonium (Po)

These elements all have:

* 6 valence electrons

* Tendency to gain 2 electrons to form -2 anions

* Ability to form covalent bonds

Here's a breakdown of some similarities and differences:

* Oxygen: Most reactive of the chalcogens, essential for life.

* Selenium: Essential trace element for some biological functions. Used in semiconductors and photoconductors.

* Tellurium: Used in alloys and semiconductors.

* Polonium: Radioactive element, used in some scientific applications.

It's important to note that as you move down the group, the properties of the elements become more metallic. This is why sulfur is a non-metal, selenium is a metalloid, and tellurium and polonium are metals.
