The noble gas krypton has the same electron configuration as an ion of bromine, Br-.
2 electrons in the first shell then 3 electrons in the second shell
bromine is bigger. bromine has an extra shell of electrons. bromine reacts less vigorously. bromine has a larger amount of protons, neutrons and electrons.
The charge if a fluorine atom were attract an extra electron from lithium the lithium atom would be positive. -APEX
1st electron shell can hold 2 electrons;2nd electron shell can hold 8 electrons;3rd electron shell can hold 18 electrons;4th electron shell can hold 32 electrons.
It has the same electron configuration as in a neon atom.
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.
2 electrons in the first shell then 3 electrons in the second shell
One electron
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
positively
bromine is bigger. bromine has an extra shell of electrons. bromine reacts less vigorously. bromine has a larger amount of protons, neutrons and electrons.
Bromine becomes basic.
lose only one electron
The charge if a fluorine atom were attract an extra electron from lithium the lithium atom would be positive. -APEX
1st electron shell can hold 2 electrons;2nd electron shell can hold 8 electrons;3rd electron shell can hold 18 electrons;4th electron shell can hold 32 electrons.
