What does the angular quantum number tell you?
The angular momentum number shows the shape of the electron cloud or the orbital. The magnetic quantum number, on the other hand, determines the number of orbitals and their orientation within a subshell.
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 orbital filling diagram has arrows pointing in opposite drections when two electrons occupy the same orbital. What do these arrows indicate?
The arrows indicate the spin of the electron, which is either +1/2 or -1/2. This it also indicates the magnetic quantum number, or the fourth quantum number.
What are the four quantumn numbers and what does each number tell us?
The principal quantum number (n = 1, 2, 3, 4, …) denotes the eigenvalue of Hamiltonian (H), i.e. the energy, with the contribution due to angular momentum (the term involving J2) left out. This number therefore has a dependence only on the distance between the electron and the nucleus (i.e., the radial coordinate, r). The average distance increases with n, and hence quantum states with different principal quantum numbers are said to belong to different shells.The azimuthal quantum number (ℓ = 0, 1, …, n − 1) (also known as the angular quantum number or orbital quantum number) gives the orbital angular momentum through the relationL2 = ħ2 ℓ (ℓ + 1). In chemistry, this quantum number is very important, since it specifies the shape of an atomic orbital and strongly influences chemical bonds and bond angles. In some contexts, "ℓ= 0" is called an s orbital, "ℓ = 1" a p orbital, "ℓ = 2" a d orbital, and "ℓ = 3" an f orbital.The magnetic quantum number (ml = −ℓ, −ℓ + 1, …, 0, …, ℓ − 1, ℓ) yields the projection of the orbital angular momentum along a specified axis. Lz = mℓħ.The spin projection quantum number (ms = ±½), is the intrinsic angular momentum of the electron or nucleon. This is the projection of the spin s = ½ along the specified axis.
Why is the periodic table called the periodic table?
The periodic table is organized in rows called periods.Periodic means Repeating Pattern. Since the chemical and physical properties of elements have a repeating pattern, the table that lists the elements is called a periodic table.
What does the angular quantum number tell you?
The angular momentum number shows the shape of the electron cloud or the orbital. The magnetic quantum number, on the other hand, determines the number of orbitals and their orientation within a subshell.
What is the definition of quantum number?
Four quantum numbers are used to describe electrons. The principle quantum number is the energy level of an electron. The angular momentum number is the shape of the orbital holding the electron. The magnetic quantum number is the position of an orbital holding an electron. The spin quantum number is the spin of an electron.
Why quantum mechanics is someone called wave mechanics?
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
What group of elements have 2 electrons in s subshell and 4 electrons in p subshell of their atoms valence shell?
It is group 16, also known as the chalcogens
What does the principal quantum number tell you?
The principal quantum number is the level of the most energetic electrons in an atom. It also corresponds to which period the element is in on the periodic table. For example, barium has a principal quantum number of 6 because its valence electrons are in level 6, and the element is in period 6.

What is a lump of energy associated with light called?
A lump of energy associated with light is called a quantum. Another lump of energy associated with light is also called a photon.
What command could you use to create a variable called TEST that is available to child processes in subshells?
If you want a shell variable to be visible to all child shells then it has to be exported before you start the subshell. For example, export TEST=hi would allow a subshell to see and use that variable. Some shells also use setenv, which does a similar thing.
What is Quantum Mechanics about?
It's the study of very small particles... so small that quantization becomes a noticeable factor in their behavior. Adding to the answer above you would also see quantum behaviour in macroscopic objects if it was not for a phenomena called decoherence - an interaction with the wider environment that wipes out quantum behavior
What does an element's atomic number tell about that emelent?
The number of protons in each nucleus of an atom of the element. Also if this element is an atom and not an ion (has no charge) the Atomic number is equal to the number of electrons in its quantum shells

The arrows indicate the spin of the electron, which is either +1/2 or -1/2. This it also indicates the magnetic quantum number, or the fourth quantum number.
Does the Quantum Superloader have to be mounted or can it run on the counter?
The Quantum Superloader can be mounted or it can also run on the counter.
