An electron is formally assigned a -1 charge. Therefore, if the ion is +1 then that means it has lost an electron- it has 11 normally, so 11-1 = 10 electrons!

A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
The cation of sodium has 11 protons and 10 electrons.
Au (gold) has a total of 79 electrons, making it the species with the greatest number of electrons among the options provided.
A sodium ion would have a charge on it, such as a positive charge, a cation, or a negative charge, an anion. Take your charge to be Na+1. This means that sodium is missing one electron, thus having one more proton giving it a positive charge. Na normally has 11 electrons, but this plus one knocks it down to 10. Neon at a neutral charge has 10 electrons. So, a sodium ion and neon atom have the same number of electrons (but only if the Na ion is +1 charge).
The number of electrons is 10.
A sodium ion with the symbol Na+ has 10 electrons. Sodium normally has 11 electrons, but when it loses one electron to form a Na+ ion, it has 10 electrons.
If you dont know this answer , well i dont either :0
The atomic number (Z) gives the number of protons in the atom. For a neutral atom, this is equal to the number of electrons. For an ion, plus or minus the number given by the charge. i.e. sodium has atomic number 11, so Na would have 11 electrons and Na+ would have 10 electrons (each electron is -1 remember)
Sodium plus oxygen react to form sodium oxide (Na2O). This reaction is a combination reaction where sodium atoms lose electrons to form sodium ions and oxygen atoms gain electrons to form oxide ions. Sodium oxide is a basic compound that dissolves in water to form a basic solution.
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
The symbol for sodium with 11 protons and 10 electrons is Na+. The plus sign indicates that the sodium atom has lost one electron, resulting in a positive charge.
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
The Mg2 plus cation has 10 electrons.
The cation of sodium has 11 protons and 10 electrons.
