Electron configurations indicate that from Be to B there are electrons in the 2p subshell, which has more energy than 2s. These 2p electrons are not as strongly attached to the nucleus as they contain more energy, therefore they are more easily removed.

In moving from Mg to Al there are electrons in 3p - the same logic as above applies.

Is magnesium's ionization energy higher or lower than chlorine?

ionization energies of mg is less than chlorine because chlorine requires only one electron to complete its octet so it will not prefer to loose its electron morover its electronegativity is also higher and it is of smaller size than mg so electtron removal is difficult


Which element has a lower first ionization energy than aluminum (Al)?

The element that has a lower first ionization energy than aluminum (Al) is magnesium (Mg). Magnesium is one period above aluminum on the periodic table, and as you move down a group or family, the ionization energy tends to decrease.

What atom has smaller ionization energy Be or Mg?

Beryllium (Be) has a smaller ionization energy than magnesium (Mg) because beryllium has a smaller atomic size and therefore the electrons are held less tightly, making it easier to remove an electron from a beryllium atom compared to a magnesium atom.


Which atom or ion in each pair has the larger ionization energy Mg or S?

Ionization Energy is the energy required to remove an electron from an atom. In general, ionization energy increases as one approaches the upper right-hand corner of the periodic table.Sulfur is quite close to the upper right-hand corner, so it has a higher ionization energy. It is a non-metal, so it wants to accept electrons to fill its outer shell to the magic number of 8. Therefore, it is very difficult to remove one of its electrons.Magnesium, however, is a metal with two eletrons in its outer shell. Metals like to donate their electrons to reach an empty outer shell -- it doesn't even want the two electrons it has -- so it is quite easy to remove one.

Why the 1st ionization energy of Na is greter than mg?

Because Be contains more protons and thus has greater nuclear positivity which exerts a stronger attraction for its electrons which requires more energy to remove one of the electrons leading to a higher ionization potential.

What is the magnitude of the energy change in the process of Mg and Mg plus?

The magnitude of the energy change in the process of Mg turning into Mg+ is the ionization energy, which is the amount of energy required to remove an electron from a neutral atom to form a singly charged ion (Mg+). This process is endothermic, meaning it requires energy input.

Is 43mg greater than or less than 5g?

43 mg is less than 5 g. To compare the two, you can convert grams to milligrams: 5 g equals 5000 mg. Since 43 mg is much smaller than 5000 mg, it is clear that 43 mg is less than 5 g.
