Both Mg and Na have the same outer energy level (shell). Mg has one proton more than NA and one electron more. The charge on th eouter shell the effective nuclear charge is reduced by the inner core electrons, which are the ame in both cases So the pull experienced by the valence electrons towards the nucleus is more in the case of Mg than Na. Hence Mg has slightly smaller size (radius) than Na.

What element has the same electrons as sodium?
The element that has the same number of electrons as sodium (which has 11 electrons) is neon. Neon is a noble gas with an atomic number of 10, meaning it has 10 electrons, while sodium has 11 electrons. The closest element with the same electron configuration as sodium would be magnesium, which has 12 electrons. However, magnesium and sodium differ by one electron.
What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?
You would observe precipitation of magnesium hydroxide.
What would be observed and why when you mix magnesium chloride and sodium hydroxide?
Magnesium hydroxide, a precipitate, is formed.
Why is it extremely unlikely that a new element will be discovered that fits between sodium and magnesium on the periodic table?
What makes each element unique is the number of protons in the nucleus. Sodium has 11 protons and Magnesium has 12 protons. The periodic table is arranged with the number of protons of each element increasing to the right and down the table. For an element to fit between sodium and magnesium it would have to have fewer than 12 protons but more than 11, which is simply not possible.
What is the atomic number of 12?
An atomic mass of 12 means carbon, and its atomic number is 6.
Why would sodium never have 12 protons?
Sodium has an atomic number of 11, which indicates the number of protons in its nucleus. Thus, sodium would never have 12 protons since that would change its identity to argon, which has an atomic number of 18.
What element has the same electrons as sodium?
The element that has the same number of electrons as sodium (which has 11 electrons) is neon. Neon is a noble gas with an atomic number of 10, meaning it has 10 electrons, while sodium has 11 electrons. The closest element with the same electron configuration as sodium would be magnesium, which has 12 electrons. However, magnesium and sodium differ by one electron.
What kind of bond would sodium have with magnesium?
Sodium and magnesium would form an ionic bond. Sodium has one electron to lose, while magnesium has two electrons to gain. So, sodium will donate its electron to magnesium to form a stable bond, resulting in the formation of an ionic compound.
What metal can displace sodium metal from sodium chloride?
You could use potassium, rubidium or caesium. However, there is no practical reason why you would do this. You'd have to do it in the melt, which would be hazardous, as all these metals react with water.
Which of these pairs of elements would bond ionically with chlorine?
Elements from Group 1 (such as sodium) and Group 2 (such as magnesium) would bond ionically with chlorine. Sodium would form NaCl (sodium chloride) and magnesium would form MgCl2 (magnesium chloride) through ionic bonds with chlorine.
What would be observed from an aqueous mixture of magnesium chloride and sodium hydroxide?
You would observe precipitation of magnesium hydroxide.
What would be observed and why when you mix magnesium chloride and sodium hydroxide?
Magnesium hydroxide, a precipitate, is formed.
What element has 12 protons and 12 neutrons?
Atomic mass is the number of protons added to number of neutrons. Number of protons is element's atomic number, and you can count neutrons by subtracting atomic number from atomic mass. So, it can be any substance which has a atomic number 12 lower than atomic mass. Basically, i would say that it is Magnesium 24 isotope [most common Magnesium isotope], because it has 12 protons and 12 neutrons [12 + 12 = 24] Sodium 23 isotope [also most common] fits perfectly too. However, it can be any other material's isotope. For example Aluminum 25 [13+12=25] Neon 22 [10+12=22]
Would beryllium or sodium have properties like to magnesium?
Sodium would have properties more similar to magnesium than beryllium. This is because sodium and magnesium are both in the same group/family (group 2) of the periodic table, known as the alkaline earth metals, whereas beryllium is in group 2. Sodium and magnesium share similar chemical behavior, such as forming similar types of compounds and reactions.
How would you explain the fact that the first ionization enthalpy of sodium is lower than that of magnesium but its second ionization enthalpy is higher than that of magnesium?
Sodium has only one valence electron, and when that is donated to some other atom, the remaining ion has a noble gas configuration that is highly stable. Disrupting that by another ionization requires much energy. Magnesium has two valence electrons; therefore the second is almost as easy to donate as the first. The third ionization enthalpy of magnesium would be very high.
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^+.
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
