How many protons and electrons in ion Br?
35 protons, 36 electrons
How many electrons are in the second shell of ion Br -1?
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
Does Br lose or gain electrons to become an ion?
Bromine (Br) gains electrons to become an ion. In its elemental form, bromine has seven valence electrons and needs one more to achieve a stable octet configuration. By gaining an electron, it forms a negatively charged ion known as bromide (Br⁻).
Would the Br ion be bigger than the Se ion?
No. The Se ion will be larger than the Br ion. The more negative the anion's charge, the larger the radius (more electrons = stronger repulsion between the electrons; so, more distance between them). Se would become "Se2-" as an anion, and Br would become "Br1-". Because Se's "2-" anion charge is more negative than Br's "1-" anion charge, and because Se would have more relative electrons to protons than Br, there is more repulsion between electrons, and distance, within the Se ion. So, the Se ion has a larger radius. Hope it helps.
How many electrons in Br?
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.
When bromine reacts to form an ion it becomes isoelectronic with?
When bromine reacts to form an ion, it becomes isoelectronic with krypton. Both bromine (Br) and krypton (Kr) have 36 electrons in their neutral state. When bromine gains one electron to form the Br- ion, it now also has 36 electrons like krypton.
Does N and Br gain or lose electron?
Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
How many electrons does Br1- have?
A Br1- ion has 36 electrons. Bromine (Br) normally has 35 electrons (according to its atomic number of 35), but since the ion has a negative charge of -1, it gains one extra electron, totaling 36 electrons.
What is the ion symbol for bromine?
The ion bromide is Br-.
How many electrons and protons does Br have?
Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet.Br- will have 35 protons and 36 electrons. The negative charge indicates it gained an electron.
What is the symbol of bromine ion?
The bromine ion is referred to as bromide, and it is Br^-
How many electrons are in chloride ion?
There are 18 electrons in a chloride ion.
