Elements for Kids Elements for Kids. Phosphorus. Phosphorus is the second element in the fifteenth column of the period table. It is classified as a nonmetal. Phosphorus atoms have 15 electrons and 15 protons with 5 valence electrons in the outer shell. Phosphorus is a highly reactive element and, as a result, is never found on Earth as a free element.

Phosphorus Phosphorus is a chemical element with symbol P and atomic number 15. As an element, phosphorus exists in two major forms—white phosphorus and red phosphorus—but because it is highly reactive, phosphorus is never found as a free element on Earth. At 0.099%, phosphorus is the most abundant pnictogen in the Earth's crust.

Phosphorus Phosphorus is a chemical element with symbol P and atomic number 15. As an element, phosphorus exists in two major forms— white phosphorus and red phosphorus —but due to its high reactivity, phosphorus is never found as a free element on Earth.Instead phosphorus-containing minerals are almost always present in their maximally oxidised state, as inorganic phosphate rocks.he glow of phosphorus itself originates from oxidation of the white (but not red) phosphorus— a process now termed chemiluminescence. Together with nitrogen, arsenic, and antimony, phosphorus is classified as a pnictogen. Phosphorus is essential for life.

Lead Lead (or Pb in the periodic table) is a naturally occurring heavy metal that is found in the Earth’s crust. Lead can be released into soil, air and water through soil erosion, volcanic eruptions, sea spray and bushfires. The natural concentration of lead in the air is less than 0.1 microgram per cubic metre.

As an element, phosphorus exists in two major forms— white phosphorus and red phosphorus —but due to its high reactivity, phosphorus is never found as a free element on Earth.Instead phosphorus-containing minerals are almost always present in their maximally oxidised state, as inorganic phosphate rocks.n 1769 Johan Gottlieb Gahn and Carl Wilhelm Scheele showed that calcium phosphate (Ca 3(PO 4) 2) is found in bones, and they obtained elemental phosphorus from bone ash. Antoine Lavoisier recognized phosphorus as an element in 1777. Bone ash was the major source of phosphorus until the 1840s.

Lead - Pb Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.

What element has the symbol P? Phosphorus, (IPA: [ˈfɒsfərəs], Greek: phôs meaning light, and phoros meaning bearer), is the chemical element that has the symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group, phosphorus is commonly found in inorganic phosphate rocks. Due to its high reactivity, phosphorus is never found as a free element in nature.

Beryllium Beryllium is the chemical element with the symbol Be and atomic number 4. Because any beryllium synthesized in stars is short-lived, it is a relatively rare element in both the universe and in the crust of the Earth. It is a divalent element which occurs naturally only in combination with other elements in minerals.

Who Discovered Niobium 21 Jun, 2012 Who discovered 0. Niobium is a soft gray metal and a chemical element represented by the symbol Nb with the atomic number 41. The free metal does not occur in nature, but it can be found in certain minerals such as columbite and pyrochlore. The largest deposits of niobium containing minerals are found in Brazil and Canada and these two countries continue to produce the majority of the element for the world. Niobium is chemically similar to the element tantalum, which meant that its discovery was the subject of much debate.

PHOSPHORUS The periodic table is a chart that that shows how chemical elements are related to each other. Phosphorus is part of the nitrogen family along with nitrogen, arsenic, antimony, and bismuth. Phosphorus was first discovered in 1669 by German physician Hennig Brand (ca. 1630-92). Brand is somewhat famous in chemistry.
