Sulfur has an atomic number of 16. sulfur will form chemical bonds in a similar manner as sulfur has an atomic number of 16. sulfur will form chemical bonds in a similar manner as carbon hydrogen oxygen nitrogen

The correct answer is oxygen.

Explanation:

Sulfur is the element having atomic number of 16. The group to which this element belongs is Group 16.

The elements which belong to same group show similar chemical properties because they have same number of valence electrons.

For the given options:

Carbon belongs to Group 14 of the periodic table and thus will not show similar behavior to sulfur.

Hydrogen belongs to Group 1 of the periodic table and thus will not show similar behavior to sulfur.

Oxygen belongs to Group 16 of the periodic table and thus will show similar behavior to sulfur.

Nitrogen belongs to Group 15 of the periodic table and thus will not show similar behavior to sulfur.

From the above information, the correct answer is oxygen.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
