1 electron which makes it belongs to group 1
1
Sodium has 1 electon in it's outer orbit, 8 in the second and 2 in the first.
One electron in 3s orbital of sodium
None - the electron goes from sodium TO the chlorine.
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.
One, because it is a group 1 metal.
Sodium has one electron in its outer ring.
The number of elements that contain the same type of outer electrons as sodium is 11.
Sodium has 1 electon in it's outer orbit, 8 in the second and 2 in the first.
One electron in 3s orbital of sodium
None - the electron goes from sodium TO the chlorine.
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.
magnesium has 2 outer electrons, its valence is 2+ sodium has 1 outer electrons, its valence is 1+
It needs to lose one electron so that it can have 8 electrons in its outer orbital
Just one.
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.
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.
One, because it is a group 1 metal.
