Lead bromide is an ionic compound and can conduct electricity when the ions are free to move - either molten or in aqueous solution. Despite lead bromide and the products of this reaction being hazardous, it is often used to show electrolysis of a molten ionic compound.

Chlorine is a stronger oxidising agent and so can easily oxidise lead from +2 oxidation state to +4 oxidation state, therefore, PbCl4 exists whereas PbBr4 and Pbl4 do not exist because bromine and iodine are weaker oxidising agents and so cannot oxidise Pb2+ to Pb4+.

Whenever continuous overcurrent flows through MCB, the bimetallic strip is heated and deflects by bending. ... As this mechanical latch is attached with the operating mechanism, it causes to open the miniature circuit breaker contacts, and the MCB turns off thereby stopping the current to flow in the circuit.

PbH4 will be formed as a result of a polar covalent bond between the H and the Pb. Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.

A piezoelectric crystal is placed between two metal plates. At this point the material is in perfect balance and does not conduct an electric current. Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance.

They are hard. They are brittle. They have high melting points and also high boiling points. They conduct electricity but only when they are dissolved in water.

In which case, the positive ion is Pb(2+) and the negative ion is I- (iodide).

They act as an inert pair of electrons and this leads to increased stability of +2 oxidation state in group 14 elements. ... Hence Pb4+ can easily gain 2 electrons to form more stable Pb2+ ions thereby acting as a strong oxidising agent.

Plays a critical role in preventing excess current surges during the starting of the AC motor. Dynamic Braking Resistors (DBR)– When the AC motor has to be brought to a stop, the VFD with the aid of the braking resistor acts like an electrical braking system instead of employing mechanical braking.

PbCl2 is ionic but PbCl4 is covalent why. The charge on Pb in PbCl2 is +2 and PbCl4 is +4. According to Fajan's rule, greater the charge on the cation, more is its ability to polarize the bonding electrons towards itself giving the compound a higher covalent character. ... Hence , PbCl2 is ionic.

In summary, ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier" - it can be transferred without moving ions too far from their mean positions.

Conduction of electricity Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Hence, the electrons flow towards the positive terminal and the base current flows (IB) is opposite to the electron flow. Besides, the current from emitter to collector starts to flow, provided the voltage VCE is applied at collector terminal. The PNP transistor can act as a switch and an amplifier.

like many ionic substances, it could under the right conditions of temperature exist as a vapor consisting of separate molecules of lead iodide, and since it is non linear molecule, Pb (II) iodide has a dipole moment and therefore it would be polar.

Lead(II) chloride (PbCl2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.

Answer: Pb has an electronic configuration of [Xe]6s2 4f14 5d10 6p2. Pb2+ would then have an electronic configuration of [Xe]6s2 4f14 5d10 since Pb2+ means that it lost two of its electrons.
