In descending order:
radon (86)
copper (29)
sodium (11)
Radon: 86 protons
11. The atomic number of any atom equals the number of protons in the atom.
Radon, with 88 protons (Na 11, Cu 29)
Sodium is an element itself, it has no elements inside.
Yes. Every element has a different number of protons.
Sodium is an element because it is composed only of sodium atoms, all of which have 11 protons in their nuclei.
Sodium element contain 11 protons. It is a alkali metal.
11. The atomic number of any atom equals the number of protons in the atom.
Sodium element is a metal. Atom contains 11 protons.
Radon, with 88 protons (Na 11, Cu 29)
Sodium, Na, is the element that has eleven protons.
Sodium has 11 protons.
Sodium chloride is a salt and copper is an element.
See the periodic system. They are numbered according to the number of protons in the nucleus. So number 11 is Sodium. It was discovered in 1807 by Davy, who called it Sodium. In 1813 Berzelius called it Natrium, and gave it the symbol Na.
Sodium has 11 protons. The element with 12 protons is magnesium
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.
Sodium is an element itself, it has no elements inside.
Yes. Every element has a different number of protons.
