How many electron can the second energy level hold?
The second electron level (n=2) can hold 8 electrons and consist of 4 orbitals. One S orbital which holds two electrons and three p orbitals each of which holds 2 electrons making 6 in all.
What is the average speed of electricity?
There are three different speeds here.The average speed of electrons - whether there is a current or not - is a significant fraction of the speed of light. That speed depends on the temperature. (The average VELOCITY of course is zero if there is no current, since as many electrons will go in one direction as in another.) The drift velocity (the average velocity) of the electrons is a small fraction of a millimeter per second. The exact value depends on the current, the cross section, and the material. The speed at which a signal can propagate in copper is about 2/3 of the speed of light in a vacuum - so, about 200,000 km/second. It is this speed that makes your light react quickly when you activate a switch.
How does the Bohr model of the atom relate to the Periodic Table?
The Bohr model of the atom places electrons in orbits or "shells." Elements in the first period only have electrons in the first shell. Elements in the second period have electrons in the first two shells. Elements in the third period have electrons in the first three shells, and so on.
How can you determine the number of electrons in an element's out energy level by the group it's in?
You can determine the number of electrons in the outer level by the goup numbers. Like aluminum (atomic number 13) will have three in the outer level. There will be two in the first inner level. in the second level there will be eight. and in the last three.

Difference between bjt and ujt?
UJT is the voltage controlled device.in which only one mejority carriers are responsible for current flowing. UJT is one junction transistor and it is three terminal emitter and two base. BJT is the current controlled device. in which both mejority and minority carrier are responsiblefor current flowing. this type of transistor consists of two junction and three terminal these are : emitter , base , collector.
How many electrons can be placed in the second energy level?
8 electrons. The second energy level (n=2) has 4 orbitals. One s orbital and three p orbitals. Each orbital can hold 2 electrons of opposite spin.

How many electrons canbe held in the second energy level?
The second energy level (n =2 ) has 1 s orbtial, and 3 p orbitals. The s contains 2 electrons, and each p contains 2 electrons (for a total of 6 electrons in the 3 p orbitals). Thus, the second energy level can hold a maximum of EIGHT (8) electrons.
