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.
Potassium has a low ionization energy.
it is bigger..so it has more electron in orbit than smaller atom...so it keep simple
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
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.
The value is not so low: 499 kJ/mol.
Low
Potassium has a low ionization energy.
The ionization energy tells us about the energy required (and thus the ease) with which an atom/ion can give away an electron (in the outermost shell). So, atoms with low ionization energies ( lowest for Caesium) give away the electron with ease
it is bigger..so it has more electron in orbit than smaller atom...so it keep simple
high
It would not take a great deal of electronegativity to pull at least the first electron off this atom.
No. Nonmetals have a high first ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
low
a process where in positive ions are formed. Here, the electrons orbiting the outer-most shell of an atom are knocked out, resulting in the atom having more protons than electrons. This creates a positive ion.
low ionization energy
It is because an atom with low ionization energy would loose an electron easily and the high electronegative atom has the tendency to attract electrons. The high electronegative atom would easily be able to get the electron from such an atom which has very low ionization energy. This is the case with Alkali metals and and Halogens. Alkali metals are highly electropositive and have low ionization energy and hence loose electrons very easily whereas Halogens are highly electronegative and have the tendency to attract electrons towards themselves.
