The protons are in the nucleus. It's the electrons that are in the "shells"
around the nucleus.
There's just one electron in the third shell of the sodium atom.
Protons won't be found in an electron shell. They are concentrated in the nucleus.
A sodium atom has 11 protons and 11 electrons including 1 outer shell electron A magnesium atom has 12 protons and 12 electons of which 2 are in the outer shell. Sodium loses its valence electron more easily than magnesium does, making the sodium much more reactive.
The atom of sodium has got 11 protons.
A sodium atom has 11 protons.
An atom of chlorine has 17 protons, while an atom of sodium has 11 protons. Therefore, an atom of chlorine has 6 more protons than an atom of sodium.
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 atomic number of an element gives its number of protons per atom. Sodium's atomic number is 11. Thus, sodium has 11 protons per atom.
firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows: first shell-2 electrons second shell - 8 electrons third shell - 6 electrons this can also be written as 2,8,6
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 :)
The atomic number is the number of protons in an atom of an element. For example, Sodium's atomic number is 11. This tells us that an atom of sodium has 11 protons in its nucleus. The interesting thing here is that every atom of sodium contains 11 protons. If an atom doesn't have 11 protons, it can't be an atom of sodium. Adding or removing protons from the nucleus of an atom creates a different element. For example, removing one proton from an atom of sodium creates an atom of neon.
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 :)
Sodium is represented by the symbol Na on the periodic table, which indicates that it has 11 protons. It is a metallic element that belongs to group 1 and has one electron in its outer shell.
