What is the symbol and number of neutrons in carbon?
An isotope of any element can be uniquely represented as AZX, where X is the atomic symbol of the element, A is the mass number and Z is the atomic number. The isotope of carbon that has 6 neutrons is therefore 126C.

Is bismuth a metalloid?
Other elements are occasionally classified as metalloids. These elements include hydrogen, beryllium, nitrogen, phosphorus, sulfur, zinc, gallium, tin, iodine, lead, bismuth, and radon.
How do you find bismuth?
Bismuth occurs naturally as the metal itself and is found as crystals in the sulphides ores of nickel, cobalt, silver and tin. Bismuth is mainly produced as a by-product from lead and copper smelting, particularly in the USA.
How do you find the number of neutrons in carbon?
Another common element, carbon, also has several isotopes. The normal carbon atom, atomic number 6, has an atomic mass of 12. Using the formula, atomic mass minus atomic number equals number of neutrons, shows 12-6=6, so the carbon-12 atom has 6 neutrons.

What is the chemical symbol for bismuth?
The chemical symbol for Bismuth is Bi. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. Bismuth is a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony.
What is the number of electrons in neutral atom of bismuth?
Therefore, the number of electrons in neutral atom of Bismuth is 83. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
What is the most common isotope of bismuth?
Bismuth occurs in 2 natural isotopes: 209 Bi and 210 Bi. Both are very slightly radioactive. 209 Bi is the most common isotope, having a natural abundance of approximately 100%. 210 Bi occurs only in traces. Bismuth-209 is composed of 83 protons, 126 neutrons, an 83 electrons.
How did the Ancients distinguish bismuth from lead?
The ancients did not distinguish bismuth from lead. The French chemist Claude-Francois Geoffroy showed that bismuth was distinct from lead in 1753. Bismuth, which has been known since ancient times, was often confused with lead and tin. Bismuth was first shown to be a distinct element in 1753 by Claude Geoffroy the Younger.
