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 in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
the number of valence electrons determine the reactivity of the atoms
Valence electrons form the bonds between atoms in a molecule.
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
There are 15 electrons in phosphorus, 45 electrons from five fluorine atoms, and they make 60 electrons altogether.
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
These electrons are called "outershell electrons" or "valence electrons."
the number of valence electrons determine the reactivity of the atoms
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
The answer is not 6 as said here before! The number of valence electrons in O2 (oxygen molecule) is: 12 valence electrons. 6 of them from each oxygen (O) atom. 4 valence electrons make up the double bond between the two oxygen atoms, and the remaining 8 valence electrons form lone pairs (non-bonding pairs) on the oxygen atoms, 2 lone pairs on each. I hope there is some help in this.
The number of valence electrons used to make sigma bonds in a molecule depends on the specific atoms and bonding arrangements present in the molecule. Generally, each covalent bond involves two electrons, one from each bonding atom. So, the total number of valence electrons used to make sigma bonds in a molecule can be determined by counting the number of bonding pairs.
alkaline earth metals or group 2 elements have two valence electrons and make +2 ion.
Molecules or covalent compounds are formed by the sharing of valence electrons.
Valence electrons form the bonds between atoms in a molecule.
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
