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
Br
yap
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
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Chlorine has a higher ionization energy. Chlorine's tendency is to gain electrons, not lose them as metals usually do.
Ionization energy decrease down the group.So in halogens,Fluorine has highest 1st ionization energy.
Argon. As you go across (left to right) on the periodic table the energy of an atom increases. Argon is farthest left of chlorine therefore making Argon have a higher ionization energy level.

The second ionization energy of sodium is so much greater than the first because the first electron is removed from the valence shell, while the second electron is removed from the core orbitals. Additionally, the sodium atom has a positive charge after the first ionization, which thus attracts the remaining electrons more strongly. Both of these factors lead to a much higher second ionization energy compared to the first.
The energy required to remove electron from atom are called ionization energy. Larger atom or molecule have lower ionization energy and molecule have higher ionization energy.
Potassium has a higher ionization energy than cesium.

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 first ionization energy of neon is higher: 2 080,7 kJ/mol.
Bromine has because the ionization energy increases as you move across and decreases as you move down.
The relationship between atomic numbers and first ionization energies is that within the same period, as atomic number increases so does first ionization because as nuclear charge increases and atomic radius decreases, electrons become harder to remove. However, within the same group, the first ionization energy decreases as atomic number increases because of the added energy level, the electrons are farther from the nucleus and easier to remove.
