# Why does na make a +1 ion mg a +2 ion?

## Why does na make a +1 ion mg a +2 ion?

Na+ because it has more electrons than Mg2+. Magnesium has more protons, so its valence shell is pulled inwards. Explain why sodium forms a 1+ ion (Na+) but magnesium forms a 2+ ion (Mg2+). They try to completely fill their valence shell, so they lose the appropriate amount of electrons.

Why does sodium make a +1 ion?

A sodium atom has one electron in its outer shell. 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.

### Why is a sodium ion bigger than a magnesium ion?

Magnesium atom is smaller than sodium atom because the nuclear charge of Magnesium ( 12+ ) is higher than that of Sodium ( 11+ ). Magnesium nucleus will attract the electrons more toward it and therefore, shrinking the size of the atom.

How does NA become Na+?

Neutral sodium atom (Na) becomes sodium cation (Na+) by releasing an electron. positive charge on the sodium cation is balanced by the negative charge on the chloride, so the ionic compound is neutral.

#### Which ion is bigger Na+ or mg2+?

Explain your answer. mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.

Which ion has the largest radius?

K+ ion
Explanation: The ionic radii of cations follow the same trends as atomic radii. They increase from top to bottom and from right to left in the Periodic Table. Thus, the ion with the largest radius is closest to the lower left corner of the Periodic Table, and that is the K+ ion.

## Is salt water ionized?

Dissolving a salt molecule in water does not make its atoms ionize. The atoms in solid salts are already ionized long before touching water. Electrons in an atom can only take on specific wave states, and only one electron can occupy one wave state at a time.

Is salt a solute?

In salt solution, salt is the solute. A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent.

### Is sodium ion bigger than magnesium ion?

(i) The sodium ion (Na+) is larger than the magnesium ion (Mg2+) due to two effects. If one were comparing just the neutral atoms Mg and S, the S atom would be smaller as both elements are in the same period and sulfur is more to the right.

Is magnesium ion positive or negative?

Chemical formulae of ions

Name of ion Formula of ion Electrical charge(s)
Sodium Na + One positive
Magnesium Mg 2+ Two positive
Chloride Cl – One negative
Oxide O 2- Two negative

#### What is the difference between Na+ and Na?

Na is symbol of normal sodium atom which have 11 protons in nucleus , with electronic configuration (2,8,1) having total 11 electrons in its all 3 shells. But Na+ is positive ion of sodium. during chemical reaction sodium atom (Na) loses his one electron present last orbit.

What kind of ion is Na+?

Sodium(1+) is a monoatomic monocation obtained from sodium. It has a role as a human metabolite and a cofactor. It is an alkali metal cation, an elemental sodium, a monovalent inorganic cation and a monoatomic monocation. Sodium cation is an Osmotic Laxative….4.3Related Element.

Element Name Sodium
Atomic Number 11

## Which is greater the ionic radius of sodium or magnesium?

The ionic radius of sodium (+1) is greater than that of magnesium (+2). Both are isoelectronic with neon, that is, they all three have the same number of electrons. But magnesium has one more electron than sodium, and therefore, the effective nuclear charge experienced by the outermost electrons of Mg^2+ is greater than for Na^+.

Why does a sodium ion have a charge of 1 plus?

In water, the scenario changes. Liquid water has OH- and H30+ ions besides the common H2O molecule. H2O and H3O+ [I’m not sure these are both the right molecules] can create stronger bonds, with an electron, than sodium, because that electron will occupy a lower energy orbital; the lowest, actually, the one present in hydrogen.

### Why does NA + form but not Na2 +?

To obtain an octet structure, sodium gives out its outermost electron (1) hence forming a single positive charge (+1). Therefore this is the reason why Na+ is formed and not Na2+. As is known Na has 11 electrons, and one in its valence shell..just one extra than needed to aquire stability.

Why does sodium not form in an ionized state?

This means that ionized sodium would be lacking one valence electron while ionized magnesium would be lacking in two. In nature such atoms would quickly want to gain electrons by bonding to negatively charged atoms. So you would not likely find them alone, in an ionized state for long.
