How many electrons are lost by 42 g of sodium when its atom are oxidized to ions?

The ion sodium is Na + so we have a one to one loss and can just find the atoms of sodium in the mass.
42 grams sodium (1 mole Na/22.99 grams)(6.022 X 1023/1 mole Na)
= 1.1 X 1024 atoms of sodium
-----------------------------------------now,
Every atom of sodium donates one electron to become a sodium ion. So.
We have.....1.1 X 1024 .......electrons lost by 42 grams of sodium ionized.

What change does the sodium atom have after combining with chlorine?
In presence of chlorine, sodium atoms will discharge electrons to give sodium ions to combine with chloride ions followed by forming a lattice of sodium chloride.
Do metals prefer to be oxidized or reduced?
Metals all prefer to loose electrons (sodium -> Na+, Fe - > Fe3+ etc.) S they prefer to be oxidised (oxidation is electron loss).
Why sodium and magnesium form positive ions?
Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.
How many protons in sodium?
the number of protons is the atomic number, which for sodium is 11. The number of electrons in neutral sodium atom is 11 and these are in the following shells:- 1st valence = 2 electron 2nd valence = 8 electrons 3th valence = 1 electrons
Which element is the reducing agent in a redox reaction?
The reactant that has the atom that gets oxidized
Difference between ions and atoms?
An atom is a particle that has the same number of protons as electrons. For example sodium. A sodium atom has 11 protons and 11 electrons. A sodium ion might have 11 protons and 10 electrons, so it would have a charge of +1. If a sodium ion had 10 protons and 11 electrons, it would have a charge of-1.
What change does the sodium atom have after combining with chlorine?
In presence of chlorine, sodium atoms will discharge electrons to give sodium ions to combine with chloride ions followed by forming a lattice of sodium chloride.
Do metals prefer to be oxidized or reduced?
Metals all prefer to loose electrons (sodium -> Na+, Fe - > Fe3+ etc.) S they prefer to be oxidised (oxidation is electron loss).
What is the structure of a sodium ion?
A sodium ion (Na+) is essentially a sodium atom which had been oxidized, losing one electron and gaining a positive charge. Thus, the atomic structure of a sodium ion is an atom with 11 protons in its nucleus, but only 10 electrons in its orbitals, thus explaining its positive charge.
When are ions formed?
Ions are formed when an atom gains or loses electrons. When an atom loses electrons the Ion that is formed has a positive charge.
Find out number of electron's in one mole of sodium ion?
Find out number of electron's in one mole of sodium ion? 1 mole of atoms = 6.02*10^23 atoms 1 mole of electrons = 6.02*10^23 electrons A Na atom has 11 protons and 11 electrons. Protons have a +1 charge and electrons have a -1 charge. A Na ion has 1 less electron than a sodium atom. One Na ion has 10 electrons. 1 mole of Na ions = 6.02*10^23 ions Each Na ion has 10 electrons. 1 mole of Na ions = 10 * 6.02*10^23 ions 1 mole of Na ions = 6.02*10^24 ions
When a sodium atom reacts with a chlorine atom to form a compound the electron configurations of the ions forming the compound are the same as those of noble gas atoms?
That is correct. A noble gas (or at least all the noble gas elements heavier than helium) has an electron configuration of 8 electrons in its outer shell, and the sodium and chlorine ions in sodium chloride also have 8 electrons in their outer shell, just like a noble gas atom.
How can you get a negatively charged ion?
When atoms lose or gain electrons, they are called ions. As electrons are negatively charged, it is when they gain electrons that they become negative ions, if they lose electrons they become positive ions. They can also form ions in pairs. for example sodium atom (NA) gives up it's outer electron and becomes an NA+ ion. the chlorine atom (CL) picks up the spare electron and becomes a CL- ion.
How does sodium sulfite remove oxygen?
The sulfite ions, with formula SO3-2, are oxidized to sulfate ions, with formula SO4-2.
A strontium atom differs from a stontiun ion in that the atom has a greater what?
electrons. Ions exist when an atom gains or loses electrons
What is the charge of ions formed from the atom of sodium?
1 (+)
Why sodium ions are more stable than sodium ions why?
If you're asking why Sodium ions are more stable than Sodium atoms, it is because most all atoms, besides Hydrogen and Helium, are more stable when they have 8 electrons in their valence shell. They all "want" to be like those atoms which have 8 electrons in their valence shell (the noble gasses). A Sodium atom has 11 electrons, and it is very easy for it to "give up" one electron to something else so that it will be like Neon, the closest noble gas.
