In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on farther and farther from the nucleus.

7 as fluorine is in 7th group of periodic table so it has 7 electrons in valence shell.
Valence Electrons. The electrons in the outermost shell are the valence electrons the electrons on an atom that can be gained or lost in a chemical reaction. Since filled d or f subshells are seldom disturbed in a chemical reaction, we can define valence electrons as follows: The electrons on an atom that are not present in the previous rare gas, ignoring filled d or f subshells.
Valence describes how easily an atom or radical can combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. Valence is denoted using a positive or negative integer used to represent this binding capacity.

The valence electrons increase in number as you go across a period. Then when you start the new period, the number drops back down to one and starts increasing again. As we discussed above, you can determine how many valence electrons an element has by determining which group it is in.
The electrons in an atom live in orbits, moving like blindingly fast planets in a cloud around the nucleus. For the transition metals (groups 3-12), figuring out the valence electrons is more complicated. Their atomic structure is such that their d subshell is incomplete.
Elements in a given group have the same number of valence electrons, and, as a result, have similar chemical properties. Things we've learned: 1) the atomic number is equal to the number of electrons in a neutral atom.

Jun 16, 2011 · Because the definition of a valence electron is the number of electrons in the outer most shell. If the electron configuration of Sr is: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2. And 2+ means it is more positive than it was before, so it lost two electrons making it. 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6
Valence: Here, sulfur in the center because of its lowest electron capability, and three oxygen around it. There are 6 electrons in the structure which we have made, and there are 24 in total. So we need to put 18 electrons down. Now fill the outer atoms so that it satisfies the octet rule.
The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly. Which metals conduct the best?
