show more If you were asked to describe metals and magnetism you could say. nonâpaired electrons spin in opposite directions in all metals, creating a magnetic field. metals are magnets because they have more electrons than nonâmagnetic materials. metals can become magnetic if they have many spinning electrons... show more If you were asked to describe metals and magnetism you could say. nonâpaired electrons spin in opposite directions in all metals, creating a magnetic field.
Not to be confused with Argonne (disambiguation). Argon is a chemical element with symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv).
Atomic Number The number of protons always equals the number of electrons in an atom, and that number is equal to the atomic number. For instance, carbon has an atomic number of six and therefore has six protons and six electrons. The Atomic Mass is the weight of an atom and is determined by the number of neutrons and protons that are present in the nucleus. Hope that helps!!!
