What is the quantum number needed to determine the size and shape of an atomic electron?

There is no single quantum number that will tell you the size of an atom.
The best answer to the question is the principal quantum number n, though it isn't a particularly good answer. While in general atoms with high maximum n tend to be larger than atoms with low maximum n, this doesn't always hold true. For example, chlorine (highest n value 3) is actually slightly smaller than lithium (highest n value 2).
Also, two atoms with the same maximum n can be significantly different in size.

The amount of energy needed to move an electron from one energy level to another is an?
The amount of energy needed to move an electron from one energy level to another is called a quantum.
What information is needed to determine the orientation of an orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
What happens to the energy needed to remove an electron as the atomic number increases down a family?
The energy needed to remove an electron from an atom generally increases, decrease as you go across a period? Explain why ? please
How many electrons are needed to complete outer shell of hydrogen?
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
Will Lithium Sodium or Potassium react the fastest?
As it has more electron shells between the nucleus and the outermost electron, and as group 1 elements react by losing there outermost electron, the more shielding effect between the nucleus and the electron, the smaller the force of attraction on the electron, so the more readily it will react as less energy is needed to break the bond between the outer electron and the positive nucleus.

How do you determine the wavelength of light needed to excite and electron from the ground state to the lowest excited state of a mercury atom?
Use the Rydberg equation.
A quantum of energy as defined in the Quantum Mechanical Model is a?
It isn't so much a matter of there being a given "quantum of energy" as much as energy is quantized. This means that particles that behave quantum mechanical laws can only have certain values of energy and not the values in between. The most popular example of this is an electron in an atom. Quantum theory tells us that the electron can be in it's ground state energy, which has a given value, or it's first excited state, which has another given value, or any higher excited state. However, you cannot observe an electron with an energy value in between the ground state and first excited state, or between any two consecutive excited states. This is what it means to have quantized energy: only certain discrete values are allowed.

How many quantum numbers?
n = 2, l = 0, ml = 0, ms = -1/2 Only the radial function R(r) of the Schrodinger wave function (psi) is needed to calculate the Energy. The radial function only deals with the principle quantum number (n). Therefore, only n is required to find the Energy. As to find the Energy states, one must specify if we are dealing with a one-electron atom situation or multiple-electron system. For one-electron atoms, the Energy states is determined by the principle quantum number (n). For multi-electron systems, the Energy states depend on both the principle quantum number (n) and orbital quantum number (l). This explanation is valid unless we are using very high resolution spectroscopic techniques, deviations will appear.
What technology did Bohr use to discover the electron?
The only technology Bohr needed to develop his model for the atom was a spectrometer, which, in the mid-1800s, revealed the emission lines of hydrogen. In 1885, Johann Balmer developed a mathematical formula (the Balmer Series) that fully described these lines, but nobody could explain why it worked. Neils Bohr combined the quantum ideas of Max Planck and Albert Einstein with the atomic model proposed by Ernest Rutherford, and developed an atomic model from which the Balmer Series could be derived.
