That, or they, would be the outer most shell electrons. The one(s) that get shared when elements bond. The one that moves out and up when struck by a photon. The one that makes light when it falls back down (gives up its' energy) to its' original shell. ADD: It is a valence electron.
Bromine has 7 electrons. Three bonds with oxygen give sic electrons and the charge gives one. Therefore, bromine has 14 electrons in valence shell in Bromate(V) ion.
number of electrons in valence (last) shell
An ionic form is created because valence electrons are transferred. A covalent bond is when valence electrons are shared.
Cation because it gives away its valence electrons in order to form an Ionic Compound, ie. LiCl
ionic
Yes, The electrons are unequally shared in an Ionic Bond. One atom has more electrons than the other atom. Every Atom has Electrons that are called Valence Electrons. These Valence Electrons are the electrons in the outer shell of the Bohr Model of the atom. There should be a stable number of Valence electrons (2 or 8) for an atom to be completely stable. To stabilize the valence electrons the atom bonds with other atoms. One type of bond is called ionic bond where one atom gives up a certain number of electrons to be stable and another atom gains all of those lost atoms.
This is the loaning (by one atom) and the borrowing (by another atom) of a valence electron or electrons that creates a chemical bond. This type of bond is the ionic bond where one atom loans (or gives up) and the other borrows (or takes) an electron or electrons. In the other bond type, the covalent bond, the two atoms involved share electrons.

Valence electrons are electrons on the outermost "level". And depending on its electron configuration, it plays a role in which if the atom requires to gain or lose electrons in order to become "stable", it can accept or give electrons to another atom in a chemical reaction.
30 valence electrons. Valence electrons are on the outer shell of a atom. To find valence electrons, subtract the amount of electrons the noble gas has before the element from the number of electrons the element actually has. Since the noble gas before carbon is Helium, you subtract 2 electrons from 6 electrons which gives you 4 valence electrons. Since there are 6 carbon atoms, multiply 4 by 6 to get 24. Do the same to the hydrogen atoms and add the valence electrons of the two molecules together and you should get 30 total valence electrons.
Bromine has 7 electrons. Three bonds with oxygen give sic electrons and the charge gives one. Therefore, bromine has 14 electrons in valence shell in Bromate(V) ion.
Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
The properties of an ionic compound are simple. My science teacher put it in a way that was easy to understand. An ionic bond is when an element gives up one or more electrons to another atom so that they will both have a maximum of 8 valence electrons. A covalent bond is when the two atoms share electron clouds and share 8 valence electrons. Co- sharing Valent- valence.
For PBr4^+ you have...Valence electrons in P = 5Valence electrons is Br = 7 and there are 4 of them so total = 28This gives a total of 33, but you subtract 1 because of the + charge on the ion,Thus total valence electrons shown in the Lewis dot will be 32.
