What is the 1st element?
Hydrogen is the "lightest" element.
Which element ha properties most similar to sulfur?
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.)
What is the 2nd lightest element?
Helium
What is the second lightest chemical element?
From gaseous elements Helium is the 2nd lightest. From solid elements Potassium is the 2nd lightest. From liquid elements Mercury is the 2nd lightest AND heaviest. (only two liquid elements: Bromium is the lightest)

Do all isotopes only occur in heavier elements?
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
