Which element is most likely to form a cation?
Which element is most likely to form a cation?
Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).
What element group is least likely to form ions?
Noble Gases
Which of the following best explains why salt water helped conduct electricity?
The salt crystals dissolve and form bridges by which electric charges move. The ions move freely in water but lose their charges. The ions move freely in water and carry electric charges.
Which substance best conducts electricity in an aqueous solution?
electrolytes
Why does an ionic solid not conduct electricity until it melts?
Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current . But when an ionic compound melts, the charged ions are free to move. Therefore, molten ionic compounds do conduct electricity.
Why is seawater a better conductor of electricity than freshwater?
Sea water has a relatively large number of Sodium and Chloride ions and has a conductivity of around 5S/m. This is because the Sodium Chloride salt dissociates into ions. Hence sea water is about a million times more conductive than fresh water.
Is distilled water bad conductor of electricity?
Distilled water is a pure type of water which does not contain any ions in it. These gases dissolve in water to form some kind of acids like carbonic acids which dissociates to give ions. Therefore distilled water does not conduct electricity.
What is the largest conductor?
The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0).
What is the size of 12 gauge wire?
Share:
| GAUGE | SWG DIAMETER (Inches) | AWG DIAMETER (Millimeters) |
|---|---|---|
| 10 Gauge Wire | 0.1280 in | 2.588 mm |
| 12 Gauge Wire | 0.1040 in | 2.052 mm |
| 14 Gauge Wire | 0.0800 in | 1.626 mm |
| 16 Gauge Wire | 0.0640 in | 1.290 mm |
What is the current capacity?
A: Current carrying capacity is the maximum number of amperes (amps) that can flow through an insulated conductor before the insulation breaks down. Heat caused by an electrical current flowing through a conductor, will determine the amount of current a wire can handle.
