What does the principal quantum number tell you?
The principal quantum number, denoted by ( n ), describes the main energy level of an electron in an atom. It indicates the average distance of the electron from the nucleus and the energy level of the electron. An increase in the principal quantum number corresponds to the electron being in a higher energy level and farther away from the nucleus.
What quantum number tell us the spin of an electron?
They act as codes that provide information about each electron in an atom. n - energy level (can be 1,2,3…) l - orbital shape (s=0, p=1, d=2) ml - orbital orientation (goes from -/to +/by integers) ms - spin (arrow up or down, and can be either +½ or -½)
What information does the periodic chart tell you?
Symbol Name Atomic Number Atomic Mass
WHAT do the period rows tell you?
The period rows in the periodic table indicate the energy levels of the electrons in an atom. Each row corresponds to a principal quantum number, with elements in the same row having their outermost electrons in the same energy level. As you move from left to right across a period, the number of protons and electrons increases, leading to changes in properties such as electronegativity and atomic size. Thus, period rows help to organize elements by their electron configurations and chemical behaviors.

What does the principal quantum number tell you?

What is the quantum number needed to determine the size and shape of an atomic electron?
The principal quantum number (n) is needed to determine the size of an atomic electron. The shape of an atomic electron is determined by the azimuthal quantum number (l) and the magnetic quantum number (m).
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.
How can you tell the difference between 1s subshell and 3s subshell?
The principal quantum number (n) distinguishes between different subshells. For example, the 1s subshell has an n value of 1, while the 3s subshell has an n value of 3. The higher the n value, the higher the energy level of the subshell.
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 quantum number tell us the spin of an electron?
They act as codes that provide information about each electron in an atom. n - energy level (can be 1,2,3…) l - orbital shape (s=0, p=1, d=2) ml - orbital orientation (goes from -/to +/by integers) ms - spin (arrow up or down, and can be either +½ or -½)
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons

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
What do quantum numbers tell us about the properties of an electron in an atom?
Quantum numbers provide information about the energy, position, and spin of an electron in an atom. They help us understand the arrangement of electrons in different orbitals and predict their behavior within the atom.
