How many protons, electrons and neutrons are in an atom of krypton, carbon, oxygen, neon, silver, gold, etc...? Units of measure have been defined for mass and energy on the atomic scale to make measurements more convenient to express. Bismuth is a brittle metal with a silvery white color when freshly produced, but surface oxidation can give it a pink tinge. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. What is the atomic number of nickel?

Mass numbers of typical isotopes of Tungsten are 182-184, 186. The chemical symbol for Boron is B. The chemical symbol for Iron is Fe. It is one of the least reactive chemical elements and is solid under standard conditions. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Tungsten is an intrinsically brittle and hard material, making it difficult to work. It is by mass the most common element on Earth, forming much of Earth’s outer and inner core. Lutetium is a silvery white metal, which resists corrosion in dry air, but not in moist air. E.
