Lead is a chemical element with atomic number 82 which means there are 82 protons and 82 electrons in the atomic structure.The chemical symbol for Lead is Pb. When we do this for #PbCl_2#, we gets..... #PbCl_2 rarr Pb^(2+) + 2xxCl^-#. Electron Configuration. 4H + 1C = 0. ; 4(+1) + C = 0 ; C = -4. The oxidation state of an atom in a molecule/ion is the charge left on the atom when all the bonding pairs of electrons are removed with the charge (the electrons) devolved to the MOST electronegative atom. ... Nitrate(NO3) has an oxidation state of -1, so since there are 2 of them, Pb has an oxidation of +2. Answer Save. 4 Answers. Electron Configuration and Oxidation States of Lead. Pb +2 S -2 + H +1 2 O -1 2 → Pb +2 S +6 O … Pb's oxidation number is the same as its ionic charge, which is +2. Lead is a chemical element with the symbol Pb (from the Latin plumbum) and atomic number 82. It looks at the increasing tendency of the elements to form compounds in which their oxidation states are +2, particularly with reference to tin and lead. Give the oxidation number of the nitrogen in each of the following compounds: a. Electron configuration of Lead is [Hg] 6p2. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). 1 decade ago +2 as shown by the fact you need 2 NO3 molecules to bond to one Pb. Lead is soft and malleable, and also has a relatively low melting point.When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Everything must equal zero out if you add all the numbers together. C in CH4 is -4. Name Symbol Oxidation number; hydrogen: H +1 +1: lithium: Li +1 +1: sodium: Na +1 +1: potassium: K +1 +1: rubidium Relevance. H is +1. Determine the oxidation number of {eq}Pb {/eq} in {eq}Pb(SO_4)_2 {/eq}. Monoatomic Ions Oxidation Numbers. +2 for Pb -2 for S. lead(II) sulfide Sulfur has an oxidation number of 2. Cross then superscript S^2 down in front of lead and there ya go. What is the oxidation number of Pb in Pb(NO3)2? What is the oxidation number for the metal in #PbCl_4#? It is a heavy metal that is denser than most common materials. Anonymous. +2(Pb)+(Sulfur's oxidation number)-6(Oxygen)= 0 This page explores the oxidation states (oxidation numbers) shown by the Group 4 elements - carbon (C), silicon (Si), germanium (Ge), tin (Sn) and lead (Pb). Possible oxidation states are +2,4. Anonymous. 1 decade ago. Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. 1 0 Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers).
