Electrons allow for chemical bonds to form.
Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
Explanation:
- Ionization energies evidence for the quantization of energy levels in atoms, as described by the Schrodinger wave mechanical model of the atom because it takes a specific amount of energy to remove the definite one electron from an atom.
- There is an approximate amount of energy which is needed to overcome the attractive force between the electrons and nucleus.
- If you put less than the required ionization energy, then the electrons can not be removed.
First off, With a hypothesis
Answer:
selenium, fluorine and neon
Explanation:
the less valence electrons an element has, the more reactive.
selenium has 6 valence electrons
fluorine has 7 valence electrons
neon has 8 valence electrons
So, it is ordered from the least number of valence electrons to the most
