If an atom with a mass number of 202 has 122 neutrons, it is an atom of which element? What is the mass number of an oxygen atom with 7 neutrons? How many protons are there in a silver atom? What is the mass number of an electron? What is the atomic mass of boron? An atom ha...
Source:Silver is found in elemental form and also in various ores such as argentite (silver sulfide, Ag2S) and horn silver (silver chloride, AgCl). Commercially, the main sources of silver arecopper, copper-nickel, gold, lead, and lead-zinc ores. Silver is extracted from the anode waste s...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. About 16 radioactive isotopes of ...
