Lead - Pb Lead is a bluish-white lustrous metal. It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity. It is very resistant to corrosion but tarnishes upon exposure to air. Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.

Lead Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains, rings and polyhedral structures.

How to Deworm a Puppy All nursing puppies should start on a deworming schedule at 2 weeks of age, and every two weeks until they reach 3 months of age. Each nursing puppy needs to be weighed on a digital kitchen scale to administer the correct amount of liquid dewormer as per the package instructions or your veterinarian's instructions.

- Lead has only one common allotrope, which is face-centered cubic, with the length of an edge of a unit cell being 349 pm. At 327.5 °C (621.5 °F), lead melts; the melting point exceeds that of tin (232 °C, 449.5 °F), but is significantly below that of germanium (938 °C, 1721 °F).ead has only one common allotrope, which is face-centered cubic, with the length of an edge of a unit cell being 349 pm.

- The products of this electrolysis are: lead metal at the negative electrode. The lead will form as a liquid at the bottom of the reaction vessel. bromine (Br 2) at the positive electrode. The bromine appears as a brown gas at the positive electrode.he copper forms as a brown solid on the negative electrode. chlorine gas (Cl 2) at the positive electrode. The chlorine appears as a gas with a characteristic smell at the positive electrode.

- Lead is a bright and silvery metal with a very slight shade of blue in a dry atmosphere. On contact with air, it begins to tarnish by forming a complex mixture of compounds depending on the conditions. The color of the compounds can vary.

Is the Lead ion anion or cation? exists and is an alternate of. Merge this question into. Split and merge into it. Answer by Chemistry4thewin. Confidence votes 1.6K. The lead ion is a cation, meaning that it has a positive charge. However, there are multiple lead cations, each with a different charge. These ions are lead (ii) and lead (iv), which have a 2+ and 4+ charge, respectively.

Metal Lead is a chemical element with the symbol Pb and atomic number 82. The symbol for lead, Pb, comes from the Latin name for the metal, plumbum. The English words plumbing and plumber are derived from this Latin name. Lead is a soft, malleable, ductile (drawn out into a thin wire) and heavy metal.

3.4 Ions and Ionic Compounds A few elements, all metals, can form more than one possible charge. For example, iron atoms can form 2+ cations or 3+ cations. Cobalt is another element that can form more than one possible charged ion (2+ and 3+), while lead can form 2+ or 4+ cations. Unfortunately, there is little understanding which two charges a metal atom may take, so it is best to just memorize the possible charges a particular element can have.

- Lead has four observationally stable isotopes, lead-204, lead-206, lead-207, and lead-208. The relative multitude of its stable isotopes relies on the fact that lead's atomic number of 82 is even, and is in fact a magic number.

Lead Background. Lead is a dense, soft, low-melting metal. It is an important component of batteries, and about 75% of the world's lead production is consumed by the battery industry. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against X-rays.his is only about half the lead used worldwide; the remainder is obtained by recycling. The top producer of lead is Australia, followed by the United States, China, and Canada. Other countries with major lead deposits are Mexico, Peru, Russia, and Kazakhstan.

- In other words, tin and lead in Group 4A can form either 4+ or 2+ charges, while bismuth in Group 5A can form either a 5+ or a 3+ charge. The transition metals usually are capable of forming 2+ charges by losing their valence s electrons, but can also lose electrons from their d orbitals to form other charges.

- The ions before mixing are Pb 2+ (aq), NO 3- (aq), Na + (aq) and Cl - (aq). The precipitate formed when the solutions are mixed is lead chloride, PbCl 2 (s). The precipitate forms because Pb 2+ (aq) react with Cl - (aq) ions to form the insoluble (ionic) solid, lead chloride. Question Three: Lead nitrate + potassium chloride  lead chloride + potassium nitrate OR. Lead nitrate + potassium chloride  potassium nitrate + lead chloride (order of the products. doesn’t matter).
