ionization energy
The energy released during the ionization of a non-metal is called the ionization energy. It represents the energy required to remove an electron from a neutral atom to form a positively charged ion.
Ionization energy is the energy required to remove an electron from an atom. A lower ionization energy means it is easier to remove electrons, making the metal more reactive. This is because metals with low ionization energy are more likely to lose electrons and form positive ions in chemical reactions.
you can think of it like a magnet.A magnet with a peice of metal stuck to it.The harder it is to pull a peice of metal away from it (ionization energy), that means that it has more pull on the metal and will pull peices of metal with more force(electron affinity).
low ionization energy
Among the alkali metals, lithium has the highest ionization energy. This is because it is the smallest alkali metal, so the outermost electron is held more tightly due to increased nuclear charge and decreased atomic size.
An element with low first ionization energy and good conductivity of heat and electricity can be classified as a metal. Metals tend to have low ionization energies, meaning they easily lose electrons to form positive ions, and their delocalized electrons allow for efficient heat and electrical conductivity.
Ionization energy is important when discussing metal behavior in a chemical reaction because it determines how easily metal atoms can lose electrons to form positive ions. Metals with low ionization energies tend to readily lose electrons and exhibit metallic behavior, such as conducting electricity and thermal energy. Metals with high ionization energies are less likely to lose electrons and may exhibit nonmetallic properties.
top right is most nonmetallic with the highest ionization energy, so the lower or closer to the left you get the more it decreases. F is the most active non-metal
A low first ionization energy is most probable for a very reactive metal. This means that the metal can easily lose its outermost electron to form a positive ion, which is characteristic of highly reactive metals.
Aluminum has a higher first ionization energy than sodium. This is because aluminum is located further to the right in the periodic table, where elements generally have higher ionization energies due to increased nuclear charge and the effective nuclear attraction on electrons. Sodium, being an alkali metal, has a lower ionization energy as it has a single electron in its outer shell that is more easily removed.
the bottom of the Periodic Table. why? a metal looses electrons and at the bottom of the periodic table is the lowest amount of ionization energy (the energy needed to remove electrons) with low ionization energy, not much energy is needed to remove those electrons making it faster and easier to do so.
Akaline metal do not exist in free state due to high level of ionization energy in them.
