Oxygen is less dense.

∙ 6y agoOxygen is less dense than selenium. Oxygen has a density of about 1.43 grams per cubic centimeter, while selenium has a density of about 4.81 grams per cubic centimeter.
Element 34, which is selenium, contains 2 protons less than krypton. Krypton has 36 protons, while selenium has 34 protons.
Helium is less dense than oxygen and nitrogen. It is about 7-8 times less dense than air, which is a mixture of nitrogen and oxygen.
Selenium can be reactive and form compounds with other elements. It reacts with oxygen to form oxides and with water to form various compounds. However, it is less reactive compared to other elements in the same group like sulfur and tellurium.
Helium is less dense than oxygen and nitrogen. Helium is the second lightest and least dense gas, while oxygen and nitrogen are heavier gases. This is why helium is often used to lift balloons, as it is less dense than the surrounding air.
Yes, warm air is less dense than cold air because warm air molecules are more energetic and spaced out. Moist air is actually less dense than dry air because water vapor molecules are lighter than oxygen and nitrogen molecules found in dry air, making moist air less dense overall.

Helium is less dense than oxygen and nitrogen. It is about 7-8 times less dense than air, which is a mixture of nitrogen and oxygen.
Element 34, Selenium, has an atomic mass of about 78.96.
Yes. Air is less dense at higher altitudes, so the oxygen is at a lower concentration.
yes, the air becomes less dense and there is less oxygen
more space for air (oxygen)
Selenium is likely to be the most brittle out of the elements listed. Brittle materials are less able to deform plastically before fracturing, and selenium is known to be a brittle element when compared to cobalt, platinum, and zinc.
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
An oxide is a compound that contains oxygen and at least one other element that is less electronegative than oxygen.
Selenium has properties most similar to sulfur. Both elements belong to the same group (Group 16) of the periodic table and have similar chemical properties, such as forming similar compounds and exhibiting similar oxidation states.
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Selenium can be reactive and form compounds with other elements. It reacts with oxygen to form oxides and with water to form various compounds. However, it is less reactive compared to other elements in the same group like sulfur and tellurium.
