AdministratorWhat ion is Na+?
sodium ion
So, Na+ is “sodium ion”.
How do you calculate the mass of sodium?
The relative atomic mass of sodium is calculated by dividing the atomic mass of sodium by the unified atomic mass unit, which is 1.66*10-27 kg. The number of 23 amu means that a normal, or stable, sodium atom weighs 23 unified atomic mass units.
What is the charge of Na+?
+1
A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.
How many ions are there in a mole of Na+?
A mole of sodium chloride is 58.443 g. It will contain 6.022 X 1023 sodium ions and 6.022 X 1023 chloride ions. Even though they are not paired off into molecules, the ratio is strictly one to one.
Which has more electrons Na or Na+?
Na has more number of electrons than Na+ because there is positive charge on Na which means it has lost one electron.
Why is Na+ an ion?
Opposite charges attract each other (positive charge attracts negative charge, and vice versa), so a collection of cations and anions is stable. Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron.
What is the formula of a sodium ion?

Which is bigger sodium atom or sodium ion?
The Na+ ion is significantly smaller than the neutral Na atom because the 3s1 electron has been removed to give a closed shell with n = 2. The Na− ion is larger than the parent Na atom because the additional electron produces a 3s2 valence electron configuration, while the nuclear charge remains the same.
