Organize the elements in group 16 - oxygen, polonium, selenium, sulfur, and tellurium - in order of increasing atomic radius.

Polonium > Tellurium > Selenium> Sulfur > Oxygen

Explanation:

In the periodic table, the trend of the atomic radius is; It increases down the group.

The elements when arranged in increasing atomic radius is given as;

Polonium > Tellurium > Selenium> Sulfur > Oxygen

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
