The sodium atom has 11 protons 11 electrons and 12 neutrons.
Sodium has 11 protons, 11 electrons and 12 neutrons.
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
equal numbers of protons and electrons
It indicates the protons. Periodic table is based on atomic number.
Sodium's atomic number is 11. Thus, neutral sodium has 11 protons and 11 electrons per atom. 23Na is sodium's only stable isotope, having 23 - 11 = 12 neutrons.
Sodium has 11 protons, 11 electrons and 12 neutrons.
Sodium (not soduim), Na, is atomic number 11, having 11 protons in nucleus
Sodium's atomic number is 11. Thus, it has 11 protons, all of them being positively charged. In order to be neutral then, an atom of sodium must also have 11 electrons.
Fluorine has 9 protons.
2 protons as its atomic number is 2
equal numbers of protons and electrons
Cl Chlorine
There are 6 protons in carbon. The weights of the different isotopes are due to different numbers of neutrons.
It still has 7 protons because isotopes of elements have variable NEUTRON numbers, not nucleon (atomic mass) or proton numbers.
Sodium has 11 electrons
It indicates the protons. Periodic table is based on atomic number.
18 protons as its atomic number is 18
