Period ---- Shell -------------- Atom pairs
1 ------------ s ---------------------- 1
2 ---------- s, p ------------------- 1, 3
3 ---------- s, p ------------------- 1, 3
4 -------- s, p, d ---------------- 1, 3, 5
5 -------- s, p, d ---------------- 1, 3, 5
Each pair represent 2 atoms. The s shell can hold 2 electrons, the p shell can hold 6 electrons, and the p shell can hold 10 electrons. The 3rd shell does not include the d shell since the atoms in the B group begin on the 3rd period
There are also some special configurations in the B group where the s shell lends an electron to the d group such as Cr. For example, if Cr followed the general guidelines that other atoms in the A groups, it would be
1s^2/2s^2 p^6/3s^2 p^6/4s^2 d^5, except it actually is 1s^2...4s^1 d^5
Special guidelines apply to group 5B for period 5 excluding 4, group 6B for periods 4 and 5, group 8B (sub groups 8, 9, and 10) for period 5, and group 1B for periods 4 and 5 (and 6 if you want to count the f subshell), where electrons from the s shell are loaned to the d shell

Do each of the elements in Group 1 have the same or different numbers of electrons?
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
What is the electron configuration?
The electron configuration is a representation of how electrons are distributed among the various atomic orbitals in an atom. It is often written using the notation of the periodic table, indicating the number of electrons in each energy level or subshell.
How is an elements period related to its its electron confuguation?
An element's period is related to its electron configuration by indicating the energy level of its outermost electrons. Each period corresponds to a new energy level, with elements in the same period having electrons in the same principal energy level. Electron configuration describes the arrangement of electrons in these energy levels, with each period accommodating a specific number of electron shells.
What is the electron configuration for boron how many unpaired electrons does each atom have?
The electron configuration for boron (atomic number 5) is 1s² 2s² 2p¹. In this configuration, boron has three electrons in its outer shell (the second energy level), specifically in the 2s and 2p orbitals. There are two paired electrons in the 1s and 2s orbitals, while the single electron in the 2p orbital is unpaired. Therefore, each boron atom has one unpaired electron.

How are subshells and orbitals related in the electron configuration of an atom?
In the electron configuration of an atom, subshells are made up of orbitals. Each subshell can hold a specific number of orbitals, and each orbital can hold a maximum of two electrons. The arrangement of electrons in subshells and orbitals determines the overall electron configuration of an atom.
The element with the electron configuration 2e- 8e- 8e- is?
The element with the electron configuration 2e- 8e- 8e- is oxygen (O), with atomic number 8. Each number in the electron configuration represents the number of electrons in each energy level (shell) around the nucleus. The electron configuration 2-8-8 corresponds to two electrons in the first energy level, and eight electrons each in the second and third energy levels.
How do the valence electrons configurations of the alkali metals compare with each other?
