2n2 where n is the electron level
K is the old symbol for the first electron shell in atoms (near the nucleus). The K shell contain max. 2 electrons.
Each inner energy level of an atom can hold a maximum number of electrons. Electrons orbit around the nucleus of an atom in shells. Each shell has a set maximum number of electrons it can hold, and the shell has to be completely filled before electrons can start filling up the next shell.
Use the formula n2 = max. number of electrons in shell. 42 = 16. 16 electrons.
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
max. 6 electrons can be accommodated
The maximum number of s electrons that can exist in any one principal energy level is 2. This is due to the Pauli exclusion principle, which states that each electron in an atom must have a unique set of quantum numbers.
This value could vary from 1 to 8.
Hydrogen only has 1 electron. However it can share electron with other elements. 1s can hold a max of 2 electrons, in hydrogen case it would be 1 ( its on electron) and then 1 more IF it is sharing with another element, but it won't go higher than that.
The maximum number of electrons in the outer energy level of any atom (the so-called valence band) will depend on the atom (element) being investigated. Different outer electron energy levels can contain a different maximum number of electrons. The energy levels, sometimes called orbitals, are designateds, p, d and f. The maximum number of electrons in the energy levels of each of these orbitals is as follows"s = 2 electrons maximump = 6 electrons maximumd = 10 electrons maximumf = 14 electrons maximumg = 18 electrons maximumIt falls on the investigator to determine the electron configuration of a given atom (element) under investigation, and, thus informed, he will be able to deduce the number of electrons in that atoms's outer electron shell.This can get complicated in a hurry, but it is easily understandible with a little work.Extra information is provided in the Wikipedia post on atomic orbitals, and a link is provided below to that article.or easier it is 32
The most electrons an outer shell for group IA metals can have is 2 because IA metals are of the s energy level the max they can hold in an orbital is 2 electrons.
This coefficient (3s) refers to the thirds-orbital in the electron cloud around the positive core. And if you're wondering what an s-orbital is: that is a "shell" or "peel" in which the max 2 electrons are most likely to be, according to some heavy calculations
