The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
A bromine atom with a mass number of 79 loses one electron to become a bromine ion with a negative 1 charge. This occurs when the atom gains an extra electron, giving it a full outer electron shell of 8 electrons, thus forming the Br- ion.
2 electrons in the first shell then 3 electrons in the second shell
An atom of chlorine and an atom of bromine both have the same number of valence electrons in their outermost shell, which is 7 electrons. This makes them both part of Group 17 of the periodic table, known as the halogens. Each atom will typically gain one electron to achieve a stable electron configuration.
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
Bromine loses an electron and forms a bromide ion by gaining one electron in the reaction with sodium. Sodium donates its electron to bromine, making the bromine atom gain one electron and become a bromide ion during the reaction.
what is the arrangement of electrons in an atom of a silicon
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
The electron pair geometry of Br3 (tribromide ion) is trigonal planar. This is due to the presence of three bromine atoms bonded to a central bromine atom, with no lone pairs on the central atom. The arrangement minimizes electron pair repulsion according to VSEPR (Valence Shell Electron Pair Repulsion) theory.
When a bromine atom gains an electron, it becomes a bromide ion with a charge of -1. This extra electron fills the outer electron shell of the bromine atom, giving it a full set of electrons and making it stable.

When a bromine atom gains an electron to form the bromide ion (Br-), it becomes negatively charged. The added electron gives the ion a full outer shell of electrons, making it stable. The bromide ion will be attracted to positively charged ions or molecules.

One electron
Bromine loses an electron and forms a bromide ion by gaining one electron in the reaction with sodium. Sodium donates its electron to bromine, making the bromine atom gain one electron and become a bromide ion during the reaction.
A bromine atom typically has seven electrons in its outer shell, which means it only needs one more electron to have a full octet of eight electrons. Bromine can achieve an octet by gaining one electron to form a stable bromide ion with a -1 charge.
