Sodium would need to gain 7 electrons to fill its valance shell. Instead of doing that, however, sodium will lose the one valence electron it does have, leaving behind the shell below it, which is already full.
Nitrogen has five valence electrons as a neutral atom, but it is shooting for eight. So it needs to gain three more 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
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.
Chlorine needs one additional valence electron to have a full valence shell, as it has seven valence electrons in its outermost shell and aims to have a complete octet with eight electrons for stability.
A fluorine atom can accommodate one more electron in its valence shell to achieve a full valence shell of 8 electrons.
Sodium has one valence electron.
Silicon has 4 Calcium has 2 Chlorine has 7 Sodium has 1
It has only 1 valence electron
Every sodium atom has only one valence electron.
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
Sodium's atomic number is 11. To be neutral then, it must have 11 protons and 11 electrons. Since sodium is in group 1, it has 1 valence electron.
electrons in Na2O
it is in the oxygen family and has 6 valence electrons it requires 2 electrons
Sodium oxide has a total of 8 valence electrons (1 from sodium and 6 from oxygen) because sodium is in group 1 and oxygen is in group 6 of the periodic table.
Sodium has 1 valence electron. It is present in group-1.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
Sodium has one valence electron because it is in group 1 of the periodic table.
