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.
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
The enthalpy of an ideal gas increases with temperature. As the temperature rises, the kinetic energy of the gas molecules also increases, leading to higher enthalpy.
There are two main elements that do not follow the trend for ionization energy. Those two elements are both Boron and Oxygen.
yes because ionization energy increases up and to the left on the periodic table. and fluorine has the highest ionization energy because it is so close to becoming a noble gas it tears off electrons from everything to complete the octete
The electronegativity trend and the first ionization energy trend both increase as you move from left to right across a period in the periodic table due to the increasing effective nuclear charge. Higher electronegativity indicates a stronger pull on electrons, making it harder to remove an electron, thus increasing the first ionization energy.
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.

Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
First ionization energy of magnesium = 870/ kj/mol First ionization energy of phosphorous = 589 kj/mol So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?
The ionisation enthalpy of potassium is lower than that of sodium.
The enthalpy of an ideal gas increases with temperature. As the temperature rises, the kinetic energy of the gas molecules also increases, leading to higher enthalpy.

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.
Which has more ionization energy available-10.5volts ,8.5volts ,6.3volts ,12.6volts.

The first ionization energy of neon is higher: 2 080,7 kJ/mol.
