What is carbon's atomic number? What are the stable isotopes of silicon? What is the mass number of an oxygen atom with 7 neutrons? What is the mass in kilograms of a single atom of carbon? What is the mass number of an element equal to?
Silicon is the second most common element in the Earth's crust. Two allotropes of silicon, amorphous and crystalline, exist at room temperature. The compound silica, also known as silicon dioxide (SiO2), makes up more than 25% of the Earth's crust. Amorphous silica usually occurs as a br...

Silicon (Si) is the second most abundant mineral element present in the soil, and silicon dioxide composes approximately 50–70% of the soil mass1,2,3,4. Si has various ecological functions, with complex roles in plant processes and in mediating interactions with the environment and other org...
but is not classed a mineral itself in its elemental form. Silicon is the second most abundant element in the Earth’s crust after oxygen, constituting about 27.7% of the Earth’s crust by mass. It is a versatile element with properties that make it useful in various applications, especially...
Silicon is a cheap, abundant, and environmentally friendly chemical element widely used in semiconductor electronic devices, for example, transistors, solar cells, etc. Bulk silicon exhibits poor TE performance, as it has inherently extremely high thermal conductivity (~150 W/mK). However, this has...
Dissolved trace metals were determined after dilution by inductively coupled plasma-mass spectrometry (ICP-MS) with a magnetic sector instrument. The amount removed was determined from the concentration of a major element, Ca. With the exception of Zn, trace metal concentrations agreed reasonably well...

Based on its important role in rice husbandry, Si has been given the status of an “agronomically essential element” in Japan and is frequently added to rice fields [24]. Lodging is a key constraint in many agroecosystems as it not only hinders the efficiency of mechanical harvesting but ...
