LEAD englannista ruotsiksi - Ilmainen Sanakirja englanti-ruotsi

The chemical symbol for Lead is Pb. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Lead has a magic number of protons (82), for which the nuclear shell model accurately predicts an especially stable nucleus. Lead-208 has 126 neutrons, another magic number, which may explain why lead-208 is extraordinarily stable. With its high atomic number, lead is the heaviest element whose natural isotopes are regarded as stable; lead-208 Lead Lead is a chemical element with symbol Pb and atomic number 82. Classified as a post-transition metal, Lead is a solid at room temperature. Element Lead (Pb), Group 14, Atomic Number 82, p-block, Mass 207.2.

Lead atomic number

Lead has been known since ancient times. It is sometimes found free in nature, but is usually obtained from the ores galena (PbS), anglesite (PbSO 4), cerussite (PbCO 3) and minum (Pb 3 O 4).Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Lead atoms have 82 electrons and the shell structure is 2.8.18.32.18.4. The ground state electron configuration of ground state gaseous neutral lead is [Xe].4f … Lead: atom sizes.
