22.99 is sodiums relative atomic mass.
This is found by making an average of all the different isotopes of sodium
Sodium has 11 protons.
The symbol of sodium is Na and its atomic number is 11.
The element with 11 protons is sodium, and its elemental symbol is Na.
If it has 11 electrons it must have 11 protons to balance the charge. So the element is Na. But you know it's going to be an isotope of Na since the number of protons and number of neutrons are different. To find out which isotope you have, you must get the mass number which is just the number of protons plus the number of neutrons (remember, they are the only ones that have mass) 11+12= 23 So you have Na-23
11...There are 11 electrons in Na1+ the only difference between Na1+ and Na is Na1+ has 1 more proton...there is no difference in electrons. Hope this helps :)
In the periodic table, "Na" represents the chemical element sodium. Sodium is an alkali metal with the atomic number 11.
11.
Sodium has 11 protons.
The symbol of sodium is Na and its atomic number is 11.
The chemical symbol for the element of Sodium is Na and its atomic number is 11.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
The element with 11 protons is sodium, and its elemental symbol is Na.
If there is 11 protons then that would be Na or Sodium.
