How does the size of a magnesium ion with a 2 plus charge compare with that of a sodium ion with a single plus charge?
The Na+ will have a larger size (atomic radius) while Mg2+ will have relatively smaller size. Both elements have lost their valence (outermost) electrons and achieve a stable octet state as ions. what makes a difference is the effective nuclear charge. because Mg has a higher nuclear charge, the valence electrons are pulled more towards the nucleus thereby reducing the atomic radius.
How do you precipitate magnesium ion out of 50-mL of 21 M solution of magnesium nitrate?
To precipitate magnesium ion, you can add a precipitating agent such as sodium hydroxide (NaOH) to the magnesium nitrate solution. This will cause magnesium hydroxide (Mg(OH)2) to form as a precipitate. You can then filter the solution to separate the precipitate from the liquid.
What are 2 likely reasons a Cl ion cannot pass through a sodium ion channel?
The size of the Cl ion is larger than the pore size of the sodium ion channel, preventing it from passing through. The charge on the Cl ion (-1) is different from that of the sodium ion channel (+1), causing repulsion and prohibiting the Cl ion from passing through.
Describe the structure of sodium chloride and magnesium oxide as solids?
Sodium chloride has a crystalline structure where each sodium ion is surrounded by six chloride ions and vice versa. Magnesium oxide has a three-dimensional lattice structure in which magnesium ions are surrounded by oxygen ions and vice versa.
Would you expect a chlorine ion to be smaller than a magnesium ion?
No, I would expect a chlorine ion to be slightly larger than a magnesium ion. Chlorine gains an electron to form a chloride ion, which increases its electron cloud size, while magnesium loses electrons to form a magnesium ion, making it slightly smaller due to the loss of electron shielding.
Infer Magnesium and sodium atoms are about the same size How does the size of a magnesium ion with a 2 charge compare with that of a sodium ion with a single charge?
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
How does the size of a magnesium ion with a 2 positive charge compare with that of a sodium ion with a single positive charge?
The magnesium ion (Mg2+) is smaller than the sodium ion (Na+) because as atoms lose electrons and become positively charged ions, they lose electron shells, making them smaller. The higher charge of the magnesium ion also pulls the electrons closer to the nucleus, further reducing its size compared to the sodium ion.

Does sodium and magnesium form an ionic compound?
Yes, sodium and magnesium can form an ionic compound. When sodium (Na) reacts with magnesium (Mg), they can form an ionic compound called sodium magnesium oxide (Na2MgO2) where sodium donates its electron to magnesium to form a stable compound.
What is the metal that is found in your body in ion form?
Examples: sodium, potassium, calcium, magnesium etc.

What does magnesium ion do in the human body?
Magnesium is very important ion inside the cell after potassium. Out side the cell you have sodium with calcium. It will be interesting to note the position of these metals in periodic table.

Sodium chloride has a crystalline structure where each sodium ion is surrounded by six chloride ions and vice versa. Magnesium oxide has a three-dimensional lattice structure in which magnesium ions are surrounded by oxygen ions and vice versa.
Which products would result from double replacement between MgCl2 and Na2CO3?
The products of a double replacement reaction between MgCl2 and Na2CO3 would be MgCO3 (magnesium carbonate) and 2NaCl (sodium chloride). This reaction occurs because the magnesium ion (Mg2+) in MgCl2 replaces the sodium ion (Na+) in Na2CO3 to form magnesium carbonate and sodium chloride.
Would you expect a chlorine ion to be smaller than a magnesium ion?
No, I would expect a chlorine ion to be slightly larger than a magnesium ion. Chlorine gains an electron to form a chloride ion, which increases its electron cloud size, while magnesium loses electrons to form a magnesium ion, making it slightly smaller due to the loss of electron shielding.
What is the equation for the reaction of magnesium ions and sodium stearate?
The reaction between magnesium ions and sodium stearate would involve the magnesium ion (Mg^2+) displacing sodium (Na^+) in sodium stearate to form magnesium stearate and sodium ions. The equation can be represented as Mg^2+ + 2(C_17H_35COO^−) → Mg(C_17H_35COO)_2 + 2Na^+.
