11
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.
Sodium element is a metal. Atom contains 11 protons.
A sodium atom has 11 protons.
The atom of sodium has got 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.
Sodium has 11 protons.
Sodium is a metal element. Atomic number of it is 1.
The amount of protons something has is equal to its atomic number. Sodium has 11 protons.
If a neutral atom of sodium has 11 protons, it will have 11 electrons also.
There are 9 protons in the element fluorine.
An element with 11 protons will have atomic number 11, or sodium. If the element has 11 neutrons, then it has an atomic mass of 11+11 = 22. Therefore, the isotope Sodium-22 has 11 protons, neutrons, and electrons.
The element is sodium with a mass number of 23. Sodium has 11 protons and thus an atomic number of 11. The mass number is calculated by adding the number of protons and neutrons, which gives 23 in this case.
