The least dense layer of water is at the surface, where the water is typically warmer and less dense due to factors such as sunlight, wind action, and mixing. This layer is known as the epilimnion, and it floats on top of the more dense layers below.
Ernest Rutherford's model of the atom disproved the Plum Pudding Model proposed by J.J. Thomson. Rutherford's gold foil experiment led to the conclusion that the atom is mostly empty space with a small, dense nucleus at the center, which contradicted the idea of electrons being randomly distributed throughout the atom.
The nuclear model of the atom was proposed by Ernest Rutherford in 1911. This model suggested that an atom has a small, dense nucleus containing positively charged protons and neutral neutrons, surrounded by negatively charged electrons in empty space.
The Earth's layers, from least dense to most dense, are the crust, mantle, outer core, and inner core. The crust is the thinnest and least dense layer, primarily composed of silicate rocks. Beneath it, the mantle is denser and made up of semi-solid silicate materials. The outer core, consisting of liquid iron and nickel, is denser than the mantle, and the inner core, a solid sphere of iron and nickel, is the densest layer.
An isotropic sphere of Osmium should be the most dense.
The planet Saturn is the least dense of all the planets.I think this is actually about the " four spheres" on Earth.The four "spheres" of the Earth's surface can be described as:atmosphere, biosphere, hydrosphere, and lithosphere.The least dense is the atmosphere.

The sphere made from the least dense material. If this is for a specific math problem, you may have to calculate density by dividing mass / volume for each sphere. The question could be about the "four spheres of the Earth" : Atmosphere Biosphere Hydrosphere Lithosphere. In that case the answer is the "atmosphere".
inner core
The "plum pudding" (as they called it) model suggest's that the electrons were dispersed throughout the atom. Where as the nuclear model has positively charged protons which are present in the center of an atom (called the nucleus)

A steel sphere will float in water if its density is less than that of water. This means the weight of the sphere pushing down is less than the weight of the water it displaces, creating a buoyant force that keeps it afloat.

Presence of dense bodies, which are structures that anchor actin filaments and help transmit force throughout the cell.
One of the most dense objects in the universe is a neutron star. Neutron stars are the collapsed cores of massive stars that have undergone supernova explosions. They are incredibly dense, with a mass greater than that of the Sun packed into a sphere only about 12 miles (20 kilometers) in diameter.
