Lithosphere and hydrosphere: oxygen
The Troposphere
The troposphere is the lowest layer of the Earth's atmosphere, extending about 8-15 kilometers above the Earth's surface. It primarily contains air and is where weather phenomena occur. The troposphere also contains various gases, such as nitrogen, oxygen, carbon dioxide, water vapor, and trace amounts of other gases.
It's the troposphere because :The troposphere contains 75 per cent of the atmosphere's gas. It also holds huge amounts of dust and water vapor, and is often dense with clouds and mist. Air pressure is greatest in the troposphere, because gravity pulls the atmosphere towards the Earth, squeezing most of its weight into this lowest layer.
Ultimately, major driving forces of weather on earth are uneven heating of the surface and moisture. The vast majority of the moisture in Earth's atmosphere is in the troposphere. The amounts in other layers are generally inconsequential. The troposphere is also the only layer that interacts directly with Earth's surface and is impacted by surface temperature, moisture content and the terrain. The other layers do not encounter such varied environments and so are realtively uniform compared to the troposphere.
No! Limestone is composed of significant amounts of calcite (calcium carbonate - CaCO3) which is soluble and so is relatively easy to weather.
Radium is a highly radioactive alkali earth metal, and it can be found in trace amounts in some water sources and in some soil or rock samples. That means this stuff isn't found in the atmosphere. (It may be in some dust, but not likely.) But it will be found in some places in the lithosphere (the ground or the earth) or the hydrosphere (the water). Radium is associated with the radioactive decay of uranium, so where traces or deposits of uranium ore are found, this stuff will be around. A link to the Wikipedia article on radium is provided.
The Troposphere
It can be harmful in large amounts, but is relatively safe in low amounts.
There is normally no life that breathes in the stratosphere. In the troposphere, both plants and animals suffer when significant amounts of ozone are present.
The atmospheric layer containing water is troposphere. It contains water vapor.

Relatively small amounts of energy are released or absorbed.

Yes it is. The hydrosphere(mostly ocean water) is made up of H2O and other chemicals such as NaCl(salt), and smaller amounts of Mg, S, Ca, and other elements as ions. (Magnesium, Sulfur, Calcium etc.)
