Br valence electrons

The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei.

Wiki User. The element bromine has 35 protons in its nucleus, and therefore in its electrically neutral state it also has 35 electrons. Two electrons fit in the innermost shell, eight fit in the next shell, eighteen fit in the next shell, which takes the total up to If we subtract 28 from 35 we get seven, voila. Counting the 4th shell orbitals and their electrons, Bromine has two 4s electrons and five 4p electrons, giving it a total of 7 valence electrons.

An element has the electronic configuration 1 s 2 , 2 s 2 2 p 6 , 3 s 2 3 p 2. Use app Login. In the electron configuration of Br , where are the valence electrons? Are they in the 3d? Open in App. Verified by Toppr. Explanation : When the five 3d orbitals have 10 electrons this subshell is filled. Being filled the d subshell becomes stable and falls into the lower third electron shell. The 4s and 3d are similar in the kinetic energy required to occupy these orbitals. The 3d is closer to the nucleus but the 3d orbitals are more complicated with up to four lobes. The 4s is farther from the nucleus but is a simple spherical orbital. The first two electrons fill the 4s but as more electrons enter the 3d subshell, the 3d is drawn closer to the nucleus and becomes the favored place for new electrons. Similar Questions.

What is the valency of bromine? Find the answer to this question and access a vast question bank that is customised for the student. Bromine has an atomic number of 35 and is a member of the halogen family. Bromine has seven valence electrons, and its valency is one. The symbol of the bromine element — Br. Bromine is a chemically reactive metal that is never pure in nature, as it reacts readily and strongly with alkali metals due to its 7 valence electrons and high electron affinity. Bromine is too reactive to exist naturally as a free element.

Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties.
