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).
Mass number-atomic number = # neutrons. Determining the number of electrons-. The number of electrons in an element can change. For a neutral atom, the number of protons is exactly equal to the number of electrons.So the number of electrons is the same as the atomic number.ass number-atomic number = # neutrons. Determining the number of electrons-. The number of electrons in an element can change. For a neutral atom, the number of protons is exactly equal to the number of electrons.
