no it does not
Yes
Potassium has a low ionization energy.
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.
The group one elements have the lowest ionization energies because of their large atomic size which makes the outermost electron only weekly held by the nucleus.
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.
Francium has the lowest ionization energy. Think of it this way, France - Francium. France has never won a war and is considered to be weak. Francium is weak!
electronegativity
Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. Ignoring the noble gases, however, group 7 halogens (F, Cl, Br, I, etc.) have the highest first ionization energy. That's because these elements have seven valence electrons, and they don't want to give up any electrons - they want another one!
Low
high
Potassium has a low ionization energy.
low
AcidicThe properties that identify the non metals are poor conductors, low densities and high ionization energies.
large atomic radii and low ionization energies
No. Nonmetals have a high first ionization energy.
1. relatively nonreactive 2. little tendency to gain or lose electrons 3. high ionization energies and negligible electronegativities 4. have low boiling points
They have low melting points and high reactivity.
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.
