There are seven horizontal rows, or periods, on the periodic table. The length of each period is determined by electron capacity of the sublevels that fill during that period, as seen below (Table below). Recall that the four different sublevels (s, p, d, and f) each consist of a different number of orbitals.
The electronic configuration of an element is related to its position on the periodic table. The links are: the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in.
Moreover, What is the electronic configuration of representative elements?
The elements of s-block and p-block except noble gases are called representative elements. The general configuration of s-block elements is ns1−ns2. And for p-block elements except noble gases is ns2np1−ns2np5. Thus combined for representative elements it is ns1−ns2p5 i.e., option A.

How does electron configuration relate to the periodic table?
The organization of electrons in atoms explains not only the shape of the periodic table but also the fact that elements in the same column of the periodic table have similar chemistry. Elements in each column have the same valence shell electron configurations, and the elements have some similar chemical properties.
What is period electron configuration?
The value of n, the principal quantum number, for the valence shell is the period of the element. Different energy levels can accommodate different number of electrons. Thus, the first period with n = 1 can hold up to 2 elements by filling the lowest level 1s. Sep 5, 2020
What does the period number tell you about the electron configuration?
the number of circles in the electronic configuration of an element is represented in the periodic table as the period number that element is situated in. the number of electrons in the outermost shell of an element is represented in the periodic table as the group number that element is situated in.

Are periods based on electrons?
There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.

How are sublevels related to the shape of the periodic table?
Why does the periodic table have the structure it does? The answer is rather simple, if you understand electron configurations: the shape of the periodic table mimics the filling of the subshells with electrons. The shape of the periodic table mimics the filling of the subshells with electrons.
What information from the periodic table helps you derive an electron configuration from the position of an element in the periodic table?
The position of each element in the table gives important information about its structure, properties, and behavior in chemical reactions. Specifically, an element’s position in the periodic table helps you figure out its electron configuration, how the electrons are organized around the nucleus.
