No, Selenium has 6 valence electrons while Bromine has 7. You can determine this because on the Periodic Table, Selenium is in Group VI while Bromine is in group VII.
Selenium and sulfur are both elements in the same group on the periodic table and share similar chemical properties. They can both form compounds with similar structures, and both have important roles in biological systems. However, selenium is less abundant in nature compared to sulfur.
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is 4. This is because the outermost electrons of an atom are located in the highest energy level, and for Bromine (with 35 electrons), the outermost electrons are in the 4th energy level.
Bromine-82 has 36 electrons since bromine has an atomic number of 35, which corresponds to the number of electrons in a neutral atom. The number of electrons remains the same in different isotopes of an element.
An iodine atom has the same number of electrons as a bromine ion. Both elements belong to the halogen group and have seven valence electrons. When bromine gains one electron to become an ion, it will have a full outer shell with eight electrons, the same electron configuration as iodine.
Bromine 81 has 35 electrons, which is the same number of electrons as a neutral bromine atom since it is the most common isotope of bromine.
Selenium has 6 electrons in its outermost shell.
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
Selenium with 6-Valence electrons
Bromine's atomic number is 35, so it has 7 valence electrons. To achieve 8 valence electrons and a full outer shell, bromine needs to gain one electron.
The number of valence electrons is seven.
no the do not bromine has 4 and oxygen has 2
Bromine, with an atomic number of 35, has 7 valence electrons. This is because bromine is in Group 17 of the periodic table, also known as the halogen group, which has 7 valence electrons.
Selenium is Atominc number: 34 It has 6 Valence electrons Therefore you take 6 from 34: 28 core electrons
Bromine (Br) has 18 core electrons. This can be determined by subtracting the number of valence electrons (7 in the case of bromine) from the total number of electrons in a neutral atom, which is 35 for bromine.
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.
4
A ground state atom of bromine has 28 core electrons. This can be determined by subtracting the number of valence electrons in a neutral bromine atom (7) from the total number of electrons in a bromine atom (35).
