How many valence electrons each noble gas has?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
How many total valence electrons make up BrO31?
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.
What gives elements in a family or group similar properties?
number of electrons in valence (last) shell
What is special about the arrangement of electrons in the noble gases?
Noble gases have a full outer electron shell, making them stable and chemically inert. This arrangement gives them little tendency to gain, lose, or share electrons with other atoms, making them nonreactive under normal conditions.
Outermost principal energy level?
The outermost principal energy level is the highest energy level in an atom where electrons are located. This level determines the chemical properties of an element, as it is the location of valence electrons that participate in chemical bonding.
When an atom completely gives up its valence electrons to another atom they form a bond that is considered to be?
ionic
How many valence electrons each noble gas has?

How many valence electrons in NF3?
There are 26 valence electrons in NF3N: 1 (5) = 5 5+21=26F: 3 (7) = 21
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
What happens when one or more valence electrons are transferred from one atom to another?
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.
What role do valence electrons play in formation of bonds?
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.
Is electrons share unequally in ionic bond?
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.
How many valence electrons need to be accommodated in the Lewis structure for LiCl?
You will have 8 valence electrons around Cl (it usually has 7 but gained one from Li). There are no valence electrons to show around Li because it gave it's valence electron to Cl. Answered by a chemistry teacher.
How many total valence electrons make up BrO31?
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.
How can you find out an element in the representative groups number of valence electrons?
To find the number of valence electrons for an element in the representative groups (Group 1, 2, 13-18), you can look at the group number. Elements in Group 1 have 1 valence electron, Group 2 have 2 valence electrons, Group 13 have 3 valence electrons, and so on up to Group 18 which have 8 valence electrons. The group number gives you the number of valence electrons for elements in the representative groups.
Elements across a series have the same number of?
valence electrons, which determine their chemical properties and how they form bonds with other elements. This shared electron configuration gives elements within the same group similar reactivity and properties.
Are the valence electrons held most tightly by the atom?
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.
