How many valence electrons dose a bromine anion contain?
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
How many valence electrons does br- have?
The anion is Br+; bromine has 7 valence electrons.
How many valence electrons does anion of OCl?
14
If an atom has four valence electrons is it an anion?
An anion is an ion with negative electrical charge.
How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
How many valence electrons dose a bromine anion contain?
The anion form of bromine, bromide, has eight valence electrons. Bromine normally has seven valence electrons, but gains to to form bromide.
How many valence electrons does HBr have?
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
How many valence electrons does br- have?
The anion is Br+; bromine has 7 valence electrons.
How do you determine which halogen has an anion with 36 electrons?
There is no halogen that will become anionic. All of the valence electrons in halogens are filled, thus halogens will not react with any other compound or element. Bromine is an element that will form and anion with 36 electrons.
How many electrons does (anion) CL have?
Chloride anion has 8 valence electrons.
How many valence electrons does cl- have?
Cl has 7 valence electrons.
What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
How many valence electrons does anion of OCl?
14
If an atom has four valence electrons is it an anion?
An anion is an ion with negative electrical charge.
How many valence electrons do the anions have when they bond?
This number is different for each anion.
What is a Group 6A element whose anion contains 36 electrons?
Bromine, atomic number 35. Each bromine atom (Br) has 35 electrons, and the bromine (or bromide) ion (Br1-) has 36 electrons.
How many electrons does a fluoride anion contain?
flouride atoms are part of the halogen group and so have 7 valence electrons. however a flouride ion is a different story. firstly it depends if the ion is an anion or a cation. if the ion is F- then it is an anion and has 1 extra electron and so has 8 valence electrons. if it is F+ is is a cation and has lost an electron and so has only 6 valence electrons. if the ion is F2- this means it has gained two electrons and so on.
