How is the periodic table used to describe atomic structure?
The periodic table can be used to describe atomic structure by using the period to tell you how many shells (principle quantum number) there are in an element, and the group number can be used to tell you the number of valence electrons in the outermost shell.
What does the period number tell about the energy levels occupied by electrons in an atom?
A period is a row in the periodic table which runs horizontally. Each atom in a period has one more electron than the previous atom. Periods feature atoms with similar principle quantum numbers. Within a period, the s and p orbitals have the same quantum number, and, if they exist in that period, the d orbital features a principle quantum number that is one lower than s and p, while that for f is two lower than s and p. Trends across a period include increasing electronegativity, decreasing atomic radius, increasing ionization energy, and increasing electron affinity.
How does the bohnr model of the atom relate to the periodic table?
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
What does the period number on the periodic table represent?
The period number represents the highest principal quantum number of the valence electrons, or the energy level of the valence (outer) shell. So, a period represents atoms with the same core electron, or noble gas, configuration, and having the same number of occupied electron shells.
Does the number of each period in the modern periodic table represents the number of?
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
What is the quantum number for helium?
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.

The periodic table can be used to describe atomic structure by using the period to tell you how many shells (principle quantum number) there are in an element, and the group number can be used to tell you the number of valence electrons in the outermost shell.
The maximum number of electrons in a period with a principle quantum number of 4 is?
2* (4^2) or 32
What are some periodic trends in elements?
A period is a row in the periodic table which runs horizontally. Each atom in a period has one more electron than the previous atom. Periods feature atoms with similar principle quantum numbers. Within a period, the s and p orbitals have the same quantum number, and, if they exist in that period, the d orbital features a principle quantum number that is one lower than s and p, while that for f is two lower than s and p. Trends across a period include increasing electronegativity, decreasing atomic radius, increasing ionization energy, and increasing electron affinity.

Periodic table relate to electrion configuration?
YES! principle quantum number is the period and we add protons neutrons and electrons as we go to the right. There is an s orbital block and a p orbital block typically what first year students focus on.
How does the bohnr model of the atom relate to the periodic table?
The quantum number of the highest occupied electron orbital in a Bohr model atom corresponds to the atom's period (row) number in the periodic table.
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 does the period number on the periodic table represent?
The period number represents the highest principal quantum number of the valence electrons, or the energy level of the valence (outer) shell. So, a period represents atoms with the same core electron, or noble gas, configuration, and having the same number of occupied electron shells.
Does the number of each period in the modern periodic table represents the number of?
The number of each period in the modern periodic table represents the number of shells. There are 7 periods in periodic table.
What information on the periodic table does the period number help you with?
Period number describes the total number of shells. There are 7 periods in periodic table.
What is the period number in the periodic table?
The period number of an element is the row in which it appears.
