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 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.
Which way does electron shells increase on the periodic table?
The number of shells in periodic table increase down the group, i.e., vertically.
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.
What is the atomic number of Periodic Table element Period?
The atomic number of the Periodic Table element Period is 92.
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 maximum number of electrons in a period with a principle quantum number of 4 is?
The maximum number of electrons in a period with a principle quantum number of 4 is 32. Each period corresponds to a principal quantum number, and the number of electrons in a period can be calculated using the formula 2n^2, where n is the principal quantum number. In this case, for n=4, 2(4)^2 = 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.

What is the atomic number of Periodic Table element Period?
The atomic number of the Periodic Table element Period is 92.
Quantum number for uranium?
The quantum number for uranium is 92, which corresponds to its atomic number on the periodic table. Each element is uniquely identified by its atomic number, which indicates the number of protons in its nucleus.
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 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.
