What else can I help you with?
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
Does the first ionization energy increase or decrease when you go down a group?
it increases
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
What is fluorine's ionization energy?
The first ionization energy is 1681 kJ/mol.
What is the energy needed to remove electrons from an atom called?
ionization potential energy. but remember the atom must be neutral .
How is the electronegativity trend related to the first ionization energy level?
When electronegativity decrease the first ionization energy also decrease.
Does the first ionization energy increase or decrease from top to bottom for the noble gas family?
The first ionization energy decrease from top to bottom for the noble gas family.
Does the first ionization energy increase or decrease when you go down a group?
it increases
What is the group trend in the first ionization energies and why?
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
What is the best explanation for the decrease in first ionization energy moving from nitrogen to oxygen?
The decrease in first ionization energy moving from nitrogen to oxygen is due to the increase in atomic size and the addition of an electron in the outer shell of the oxygen atom, making it easier to remove an electron.
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.
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
Which property has a trend similar to that of electronegativity?
First ionization energy has a trend similar to that of electronegativity.
What is first ionization energy?
Sodium's first ionization energy is 495 kJ / mol.
Which element has a higher first ionization energy than chlorine Cl?
The element with a higher first ionization energy than chlorine Cl is fluorine F. Fluorine is located to the left of chlorine in the periodic table, which means it has a smaller atomic radius and stronger nuclear attraction, requiring more energy to remove an electron.
What element has largest first ionization energy?
Helium has the highest ionization energy.
What is fluorine's ionization energy?
The first ionization energy is 1681 kJ/mol.
