Write the corresponding electron configuration for the following pictorial representation.

Before the 4p orbit starts to fill, the element must have:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰,  

which is Zn.  

Depending on the number of electrons in the 4p, the element might be Ga to Kr, inclusive

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
