Question:

               What are the symbols of the four quantum numbers used in the specification of electrons in atoms?

              The four Quantum Numbers along with Symbol and brief explanation are as follow,

1) Principal Quantum Number:

          Symbol = n

This quantum number explains the main energy level or main shell in which an electron is present.

2) Azimuthal Quantum Number:

          Symbol = l

This quantum number is associated with principal quantum number and it represents the sub energy levels or sub shells.

3) Magnetic Quantum Number:

          Symbol = m

This quantum number explains the magnetic properties of an atom. Electrons with different magnetic quantum numbers have different orientations in applied magnetic field.

4) Spin Quantum Number:

          Symbol = s

This quantum number explain the spin of an electron about its axis. The spin may be clockwise or anti-clockwise.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
