Unlike phantom power, bias does not require a balanced circuit. Bias supplies power to a Junction Field Effect Transistor (JFET) connected to the output of an electret condenser mic element. The JFET acts as an impedance converter that is a necessity in any microphone design that uses a condenser element.
Iodine atoms have 53 electrons and the shell structure is 2.8.18.18.7. The ground state electron configuration of ground state gaseous neutral iodine is [Kr].4d10.5s2.5p5 and the term symbol is 2P3/2.
This allows two iodine atoms to bond together, each sharing the same pair of electrons and each having an apparent full outer shell. (Original post by Yelleanor). I have the question Explain, in terms of covalent bonding, why iodine exists as simple molecules and carbon does not..I found the exact same question on TSR but it was like the replies were in a different language, and im still none the wiser.Original post by charco) Iodine atoms have 7 electrons in the outer shell. They acheive a full apparent outer shell by sharing one pair of electrons. This allows two iodine atoms to bond together, each sharing the same pair of electrons and each having an apparent full outer shell. Thank you, you beautiful person.
