Phosphorus is a chemical element. So it existed long before man appeared on earth and is, therefore, definitely not man-made. However, because it is so reactive it is never found in its pure form on earth. Thus, any quantity of the pure substance must be made by us from one of the phosphorus compounds that occurs naturally.

Is sodium hydroxide natural or synthetic?
Sodium hydroxide is a manmade substance.
Metal is a natural or synthetic substance?
i don't know is it man made or natural?
What isotope iodine iron phosphorus radium has the longest half-time?
Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
Why is phosphorus named phosphorus?
phosphorus means "bringer of light".
What is an element of the periodic table beginning with p?
Phosphorus
How do you spell synthetic?
That is the correct spelling of "synthetic" (manmade by chemical synthesis).
Is phosphorus natural of synthetic?
Phosphorus is an element. It's natural.
Is potting soil natural or man made?
Is phosphorus manmade or nutural
Is sodium hydroxide natural or synthetic?
Sodium hydroxide is a manmade substance.
What are synthetic codeine?
Synthetic codeine is just codeine made in a lab by scientists, synthetic means fake which is unnatural which is man made so manmade codeine
What is the difference between a bio-polymer and a synthetic polymer?
Both the polymers have a repeating structure which is the basic definition of polymer.
What is the difference between synthetic and regenerated fibres?
I don't think that there is much difference between the two.
Metal is a natural or synthetic substance?
i don't know is it man made or natural?
How are synthetic pearls made?
Synthetic is not a term used to describe imitation pearls. Synthetic, in the case of gemstones, is completely manmade, and it has to have the same structure, constituents, and chemistry as its natural counterpart. No cultured pearl is completely manmade. There is always human intervention, but the mollusk grows the cultured pearl. Of cultured pearls, only tissue-nucleated and keshis have the same structure, constituents, and chemistry as their natural counterparts, but they result from human intervention. So when the two criteria that determine a synthetic gem are applied, there is no cultured pearl or imitation that meets both. Therefore, no cultured pearl or imitation is a synthetic.

Phosphorus, iron, and iodine all have at least one isotope that is stable, and any of these would do for the longest half life. In fact, the radioactive isotopes of phosphorus are all synthetic, so radioactive phosphorus is not found in nature.
What does the Organic Fibers--Noncellulosic industry consist of?
Establishments primarily engaged in manufacturing noncellulosic, or synthetic, fibers comprise the manmade organic fibers industry.
Is there less phosphorus in organic grown foods?
The foods that contain phosphorus are more likely to have more phosphorus if they are grown organically. This is due to organic practices that build up the soil with compost, non-synthetic fertilizers, etc. In addition, organic methods help to replenish micronutrients, which are needed for optimal health. Synthetic fertilizers are usually nitrogen, phosphate, and potassium, but lack macronutrients.
