Natural isotopes of silicon are:
28Si - 92,23 % (stable)
29Si - 4,67 % (stable)
30Si - 3,1% (stable)
31Si - traces (radioactive, unstable)
32Si - traces (radioactive, unstable)
Silicon is not converted to magnesium in earth; some artificial isotopes of silicon decay to magnesium isotopes.
Yes: Naturally occurring silicon contains isotopes with mass numbers 28, 29, and 30 in order of decreasing abundance. As with almost any element, many artificial, radioactive isotopes are also known.
The average atomic mass of silicon is around 28.09 atomic mass units. This is due to the natural abundance of the three silicon isotopes: silicon-28, silicon-29, and silicon-30. Silicon-28 is the most abundant isotope at about 92.23%, followed by silicon-29 at about 4.67%, and silicon-30 at about 3.1%.
The atoms of all three isotopes have the same number of protons (14) and electrons, but differ in the number of neutrons: silicon-28 has 14 neutrons, silicon-29 has 15 neutrons, and silicon-30 has 16 neutrons. This variation in neutron number gives each isotope a different atomic mass.
Yes Neon has isotopes from 16-34.

Naturally occurring silicon, of which there are three isotopes, is not radioactive, There are a half dozen artificial radioisotopes.
The chemical symbol for the element Silicon is Si. If you wanted to distinguish Silicon 29 from other Silicon isotopes you would write 29Si.
Some common compounds made from silicon include silicon dioxide (silica), silicon carbide, silicon nitride, and silane. Silicon dioxide is found in materials like quartz and sand, while silicon carbide and silicon nitride are used in ceramics and abrasives. Silane is a precursor to silicones, which are used in sealants, adhesives, and lubricants.

The common name of silicon carbide is carborundum.

Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
