-Hydrogen is the lowest density solid

2.which element has the highest?
Osmium

Certainly! When it comes to the lowest density element in solid form, hydrogen is indeed one of the least dense elements. To confirm this, we can consult the periodic table and look for the element with the lowest atomic mass. Hydrogen has an atomic mass of approximately 1 gram per mole, making it the lightest element on the periodic table.

Now, let's move on to the element with the highest density in solid form. To determine this, we need to consider elements known for their high atomic masses. One such element is osmium, which has an atomic mass of approximately 190 grams per mole, making it one of the densest elements.

To summarize:
- The element with the lowest density in solid form is hydrogen.
- The element with the highest density in solid form is osmium.
