how many electrons present in na+?
3464
There are 10 electrons present in Na+. The atom of sodium has 11 electrons, 11 protons along with 12 neutrons, but Na+ contains one less electron, 11 protons along with 12 neutrons, as the ion has lost 1 electron.

From top to bottom of the periodic table ions will increase in radii. However, now left to right the radius is more of a function of the number of electrons. Mg2+ is smaller than Na+. Both have 10 electrons but Z=12 for Mg and Z=11 for Na.

The ions present in NaCl is one ion of Na and one ion of Cl.

1 molecule of Na2SO4 contains 2 atoms of Na, 1 atom of sulfur and 4 atoms of oxygen.

Mg2+ ion is formed by loss of two electrons by Mg atom. Therefore, it has two electrons less than the number of electrons in Mg atom. Number of neutrons = (24- 12) = 12.

Sodium Chloride or NaCl is made up of two elements, sodium (or Na) and chlorine (or Cl). A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total.
82627
Sodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom.

CLASS PRACTICE 3 a. What four ions are present in sodium chloride solution? Na+(aq), Cl-(aq), H+(aq), OH-(aq) b. In Figure 21.3, write the ionic equation.

Number of electrons in a chloride ion is 17. Hence, it needs one more electron to complete its octet. Its valence electrons are the number of electrons present in its outermost shell, i.e., 7.
231692
Sodium has 11 electrons. The first two fill the innermost energy level. The second energy level is also full, holding eight electrons and one electron remaining in the outer energy level. It is the number of outer electrons that give an element its chemical properties.

In 1 mol Nacl , there is one mole of Na+ and one mole of Cl- ions . Therefore there are Total two moles of ions in one mole of NaCl .

The sodium atom is left with a full outermost electron shell with eight electrons, and the outermost shell of the other atom is full as well.
753172
So, sodium's 11 electrons are arranged this way: 2 electrons in the first "shell", 8 electrons in the second "shell"; and 1 electron (the valence electron) in the third "shell". We write this as 2.8. 1. The last number is how we know the number of valence electrons.

The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element's atomic number, which is same 11. The number of neutrons can be found by subtraction of the atomic number from sodium's atomic mass of twenty three.
496402
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).

So, each unit cell has 4 atoms of each Na+ and Cl-. Hence there are total 4 molecules of NaCl in each unit cell. As the mass of -Avogadro number of molecules- of NaCl is 58.5g.
