How many valence electrons does an ionic bond have?

Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.


Why does carbon bond with so many elements?

it has 4 valence electrons


How many valence electrons does Br2 have?

Br2 has a total of 14 valence electrons, with each Br atom contributing 7 valence electrons. This allows them to form a covalent bond by sharing electrons with each other.


How many total valence electrons take part in triple bond between 2 atoms?

In a triple bond between two atoms, a total of six valence electrons take part. Two electrons come from each atom to form the sigma bond, and the remaining four electrons form two pi bonds.


How many valence electrons do all the cations have when they bond?

Cations have fewer valence electrons than the number they started with. The number of valence electrons that cations have after bonding is dependent on the element they originate from.


How many valence electrons does an atom of nitrogen have?

Nitrogen can have either 3 or 5 valence electrons. The number changes because the 2 electrons from the 2s shell can bond as well as the 3 electrons in the outer 2p shell.


What aspects of an atom determine how an atom will bond to another atom?

The number of electrons in the outermost energy level (valence electrons) and their energy levels determine how an atom will bond to another atom. Atoms tend to bond in a way that allows them to achieve a stable electron configuration, often by either gaining, losing, or sharing electrons to fill their outer energy level.


how many hydrogen atoms must be bond to silicon to give it an octet of valence electrons?

Silicone has 4 valence electros so it would need 4 hydrogen atoms to give itself an octet of valence electrons.


How many valence electrons occupy sigma bond orbitals an pi bond orbitals in c14h10?

26 sigma 7 pi


How do you tell how many valence electrons in an element?

the group in which an element falls = # of valence electrons eg Na gp 1 = 1 valence e Ca, gp 2 = 2 valence e and so on....... the number of covalent bond an element makes really depends on which other element it bonds with but note this a covalent bond consist of 2 electrons so how many covalent bonds formed will depend on how many electrons an atom has in its valence shell - covalent bond are mostly between non metals and involves electron sharing carbon forms the longest chain of covalent bonds with itself...


How many valence electrons does the nobel gas group have?

Noble gases have a full valence shell with 8 electrons, except for helium which has 2. This makes them very stable and unreactive.


How many valence electrons does indium?

Indium has 3 valence electrons.
