This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
8
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
4 electrons
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
It is always 2. The first shell will be 1s2
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.
The sodium atom (Na) has 11 electrons. The electron configuration of sodium is 2-8-1. The third noble gas shell is the second energy level or shell, which can hold a maximum of 8 electrons. Therefore, the number of electrons in the third noble gas shell of sodium is 1.
the sodium atom has 3 shells where 2 electrons are in the first shell, 8 in the second and 1 in the third shell; which isn't stable..... and its symbol is Na :)
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
the sodium atom has 3 shells where 2 electrons are in the first shell, 8 in the second and 1 in the third shell; which isn't stable..... and its symbol is Na :)
8
8 electrons
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
4 electrons
The second orbit has 8 electrons.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
