Ionization energy is the energy needed to remove an electron. Elements other than transition metals gain or lose electrons from the s and p orbitals in order gain the more stable electron configuration of a Noble gas. Metals lose electrons to become isoelectronic (that is have the same electron configuration) to a noble gas (previous to them in the Periodic Table), while nonmetals tend to gain electrons in order to become isoelectronic to a Noble gas (next highest on the periodic table). Since ionization energy is the energy needed to REMOVE an electron, it is low for metals which form positive ions by losing electrons to become more stable, but very high for nonmetals that tend to gain, NOT LOSE, electrons. Most transition metals tend to lose electrons as well (other than Rhenium). Transition metals lose electrons from the d orbital, but still form positive ions, so their ionization energy is also usually lower than nonmetals.
What else can I help you with?
Is alkali metal more reactive than transition metal?
Yes, alkali metals are more reactive than transition metals. This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.
How does metallic character relate to first ionization energies?
Metallic character increases down a group and from right to left across periods on the periodic table. A decrease in first ionization energy corresponds to an increase in metallic character, as it becomes easier for metals to lose electrons and form cations. Metamorphic metals have lower first ionization energies than nonmetals.
Why is ionization energy important when discussing metal behavior in a chemical reaction?
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.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
Based on the periodic table which element would be expected to have the lowest ionization energy?
Francium would be expected to have the lowest ionization energy, as it is located in the alkali metal group at the bottom left of the periodic table. Alkali metals typically have the lowest ionization energies due to their large atomic size and low effective nuclear charge.

This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.

Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
Why do the alkali metal have lower ionization energies than the alkaline earth metals?
Alkali gases only have 1 electron needing to be removed to reach a stable noble gas configuration. Alkaline earths have two electrons. Alkali metals thus have the lower ionization energy of the two groups.
How can an element that has a low first ionization energy and good conductivity of heat and electricity be classified?
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.
How does the reactivity of an alkaline earth metal compare with that of alkali metal in the same period?
Alkaline earth metals are less reactive than alkali metals in the same period because they have higher ionization energies and are less likely to lose electrons. Alkali metals readily lose their outermost electron to form a +1 charge, whereas alkaline earth metals require more energy to lose their outermost two electrons to form a +2 charge.
Why do metals tend to loose electrons?
Metals tend to lose electrons because they have low ionization energies, meaning it requires less energy to remove an electron from a metal atom compared to non-metal atoms. This allows metals to easily form positive ions by losing electrons, which helps them achieve a more stable electronic configuration.
Chemical properties of metal?
•They have low ionization energies •Tend to form complexes •Good conductors of heat and electricity

Why does copper conduct heat faster then steel or brass?
Copper's conductivity properties are based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
