This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
The outermost energy level of a atom is where the valence electrons are found.
The valence shell is the outermost energy level of an atom.
The energy level in which the valence electrons are held are known as the atoms outermost energy level.
valence electrons
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
Magnesium atoms have two electrons in their outer shell; it is these that will be lost, to turn the Mg atom into an Mg2+ ion.
The first energy level can hold 2. The second level can hold 8. The third level can hold 18. Fourth and beyond can hold 32.
Nitrogen has 5 valence electrons. Valence electrons are the electrons that are found in the outer most shell of an atom, and are consequently the electrons that move from atom to atom in the formation of compounds. The reason for this is a result of the electron configuration. A nitrogen atom has 3 orbitals; the 1s orbital, the 2s orbital, and the 2p orbital. In this case, the 2s and 2p orbitals are the valence orbitals, as they have the electrons with the most energy. With 7 protons, a neutral nitrogen atom has 7 electrons. The s orbitals can only hold 2 electrons, and the p orbitals can hold up to 6 electrons. The 1s orbital is filled first, leaving five electrons, then the 2s orbital is filled, leaving 3 electrons, and then these remaining electrons fill the 2p orbital halfway. There are a total of 5 electrons in the 2s and 2p orbitals, and since these orbitals have the most energy, there are 5 valence electrons.
Glass is clear because of the minerals. Rocks and Minerals get melted in a huge container and they let it cool. Then it just hardens and you get that clear view from the melted rocks and minerals. ***That answer is wrong*** I'll explain it as simply as possible so that you can understand the kind of thing that happens but to really understand you'll have to study the topic and get to understand how atoms, molecules and photons work. Basically, understand that in an atom there are levels of energy... for the sake of understanding just think of it sort of like an onion. There are layers, each layer furthest from the center is a higher energy. Electrons in a given atom have an energy level in the atom where they are generally most comfortable and they stay there most of the time. When a photon comes along (particle of light) it will want to take that spot where the electron is. It will try to knock the electron out of the way to make room for itself. Now, the photon only has a certain amount of energy. Depending on, due to the specific type of atom we are talking about, how far away the next available level of energy is and therefor how much energy is needed to knock the electron out of its place to the next energy level, the photon may or may not have enough energy to succeed in getting the electron out of the way so that it can claim its energy space (get absorbed by the atom). If the photon meets a type of atom that has an accessible energy level for the photon to displace the electron than the photon gets adsorbed and the substance is opaque. If the atom's next energy level is too high, and the photon does not have the energy to move the electron to the next level, than the photon passes through and the substance is transparent. There is more to it but that will give you the idea.
Valence electrons
The electrons on the outtermost energy level of an atom is called a valence electron.

Valence electrons.
In a neutral carbon atom, there will be 4 electrons in the outer most valence shell.
The outer energy level is the strongest because it has more electrons in it.
When less than half of the outer energy level is filled!
by the number of electrons lost or gain by the atom to complete it's outer most energy level example : magnesium's atomic number is 12 so the electronic configuration in the 7 energy levels K L M N O P & Q will be 2-8-2 so the atom tends to loss 2 electrons so the valency of Magnesium is 2. note: in the outer most energy level if the electrons are 1-2-3 the atom tends to loss them , 4 the atom tends to share , 5-6-7 the atom tends to gain IN ORDER TO complete the outer most energy level with 8 electrons except when the outer most energy level is K it needs only 2 electrons to be completed.
A negatively charged atom is a electron.
Electrons are those found in the outermost energy level of an atom?They are called valence electrons.
Yes, bonds and reactions are caused by the valence electrons only (the outermost principle energy level).
