Rather than to give a simple number as answer, I suggest to look up Magnesium on wikipedia, where you will even find a picture with the electron configuration.

(And this method can be applied to answer the same question for any other element.)

Which of these elements has the same number of electron orbitals as the element sodium?

The element magnesium has the same number of electron orbitals as sodium - both have three electron orbitals. Sodium and magnesium are in the same period on the periodic table, which means they have the same number of electron shells.


How many electrons shells does magnesiun have?

Magnesium has three electron shells. The electron configuration is 2,8,2


What is different in number of shells in magnesium and sulphur?

There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.


What is the correct number of shells neptunium the element has?

Neptunium has 7 electron shells.


Is it true Iodine has four electron shells?

No, iodine has four electron shells, marked as "K", "L", "M", and "N". The number of electron shells is determined by the electron configuration of an element.


What can the period of a element be determined by?

The period of an element in the periodic table can be determined by the number of electron shells or energy levels that the element's atoms have. Each period on the periodic table corresponds to the number of electron shells occupied by the elements within that period.


How many shielding atoms does magnesium have?

Magnesium has 3 electron shells.


Does mg have the same number of atomic shells as na?

No, magnesium (Mg) has 3 atomic shells while sodium (Na) has 2 atomic shells. The number of atomic shells is determined by the number of electron shells in an atom.


How many shells does magnesium atom have?

A magnesium atom has 12 electrons arranged in 3 shells. The electron configuration of magnesium is 2-8-2, indicating that it has 2 electrons in the first shell, 8 in the second shell, and 2 in the third shell.


What element has 4 shells?

The element with 4 electron shells is potassium (K).


Which element is in group v of the periodic table and has 3 electron shells?

The element in group V of the periodic table with 3 electron shells is Phosphorus (P). Group V elements have 5 valence electrons and the number of electron shells corresponds to the period number on the periodic table, so a Group V element with 3 electron shells is in period 3.
