What does 1s2 2s2 2p6 mean?
It means there are 2- electrons in first energy level s-subshell and 2-electrons 2nd energy level s- sub shell and 2-electrons in 2nd energy level p-sub shell.
What is the purpose of the electron configuration?
Commonly, the electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals.
What does the electron configuration tell you?
It tells you how many electrons there are in each of the different orbitals (s, p, d, or f) and at which energy level (n= 1, 2, 3.).

What element has the electron configuration 1s22s22p63s23p4?
The name of the element with electron configuration 1s22s22p63s23p2 is silicon. The second most abundant element in the Earth’s crust, silicon is a metalloid, an element that is neither metal nor nonmetal.
What is the electron configuration for the periodic table?
Electron configuration. An electron configuration is the arrangement of electrons within an atom. The electron configuration describes where the electrons are inside orbitals. The structure of the Periodic table of elements is partly based on electron configuration. There are four kinds of electron configurations: s, p, d, and f orbitals.
What is the electron configuration of an oxygen atom?
Oxygen is the eighth element with a total of 8 electrons. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital.
