because ionization energy increases from left to right on the Periodic Table. Ionization energy is the amount of energy needed to take an electron away from the atom, or the energy needed to ionize it. Since Sodium is more likely to give up an ion to complete the octet rule, it has a higher ionization energy.
What else can I help you with?
Why is it easier to remove an electron from a sodium atom than from a magnesium atom?
Phosphorus has a higher energy level so it pulls harder on its electrons.
Sodium is more or less active than magnesium?
Sodium is less active than magnesium. Magnesium is located higher in the reactivity series of metals than sodium, indicating that magnesium is more reactive and likely to form compounds with other elements compared to sodium.
Why is the first ionisation energy of magnesium higher than that if sodium?
It has to do with the VSEPR model for electron shell configurations. Zinc being the final transition metal in the 4th row of the periodic table has a full "D" shell of valance electrons. Gallium being the following element in the 4th row now has one valence electron in the "P" shell which is not full. An element with a full valence shell of whatever type will have a higher first ionization energy then an element with a shell that is not full.
Why Magnesium metal is a better conductor than Sodium metal?
Magnesium metal is a better conductor than Sodium metal because it has more free electrons to carry electric charge due to its atomic structure. Magnesium has two electrons in its outer shell, compared to Sodium's one, making it a more efficient conductor of electricity. Additionally, the higher atomic mass of Magnesium allows for better mobility of electrons, resulting in higher conductivity.
What happens in the reaction between sodium hydroxide and magnesium sulphate?
When sodium hydroxide reacts with magnesium sulfate, a double displacement reaction occurs where the sodium ions from sodium hydroxide switch places with the magnesium ions from magnesium sulfate to form sodium sulfate and magnesium hydroxide. The products of this reaction are aqueous sodium sulfate and a white precipitate of magnesium hydroxide.
Which substance sodium oxide or magnesium oxide has higher melting point?
sodium oxide: 1132oC magnesium oxide: 2852oC

Why second ionization energy of sodium is greater than that of magnesium?
The second ionization energy of sodium is greater than that of magnesium because, after the removal of one electron, sodium achieves a stable noble gas configuration (Neon) with its remaining electrons, making it more stable and requiring more energy to remove the second electron. In contrast, magnesium, which has a higher nuclear charge and a full outer shell of electrons, experiences less effective nuclear attraction on the second electron due to its configuration. Consequently, the energy needed to remove the second electron from magnesium is lower than that for sodium.
Will sodium react with magnesium?
Yes, sodium will react with magnesium to form a compound called sodium magnesium alloy. This reaction typically involves the transfer of electrons from the sodium atoms to magnesium atoms. It is a highly exothermic reaction that can result in the release of significant amounts of energy.
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 happens when magnesium is added to sodium hydrogensulphate?
When magnesium is added to sodium hydrogensulphate, a reaction occurs where magnesium displaces sodium due to its higher reactivity. This results in the formation of magnesium sulfate and sodium metal. The reaction can be exothermic, producing heat and potentially leading to the ignition of hydrogen gas released during the process. Overall, this displacement reaction showcases the reactivity differences between these metals.
Which ionic compound would be expected to have the highest lattice energy?
Lattice energy is influenced by the charges of the ions and the distance between them. Among ionic compounds, those with higher charges and smaller ionic radii typically exhibit higher lattice energies. For example, magnesium oxide (MgO) has a higher lattice energy than sodium chloride (NaCl) due to the +2 charge of magnesium compared to the +1 charge of sodium, as well as the smaller size of the Mg²⁺ ion compared to Na⁺. Thus, MgO would be expected to have the highest lattice energy among common ionic compounds.
