Its electron configuration is 1s22s22p63s1.
A good Periodic Table that includes electron configurations can be found under related links.
None - the electron goes from sodium TO the chlorine.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
8 electrons on the outer shell
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
None - the electron goes from sodium TO the chlorine.
Sodium has ONE valence electron in its outer shell that is to be donated to any kind of oxidant. By then the outer (3rd) shell (of the Na+ ion) is EMPTY, so the 2nd shell has become the outmost, containing 8 electrons (Ne-configuration). No electrons at all are taken up by sodium.
Just one.
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
8 electrons on the outer shell
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
2 outer shell electrons
One, because it is a group 1 metal.
