As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals,
Lithium > Sodium > Potassium > Rubidium > Caesium > Francium

Which elements are more reactive with oxygen group 1 or group 11?
Elements in group 1 (alkali metals) are typically more reactive with oxygen compared to group 11 (coinage metals). This is because alkali metals have a lower ionization energy and are more likely to form ionic compounds with oxygen.
How do the reactivity of the alkali metals change in group 1?
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
What is the trend for first ionization energy for the alkali metals?
The trend for the first ionization energy of alkali metals decreases as you move down the group from the top. This is due to the increase in atomic size and shielding effect, which allows easier removal of the outermost electron.
Why do alkali metals have lower ionization potentials than alkaline earth metals?
Noble gases have the highest ionization energies of the elements because they don't "want" to lose any electrons. All atoms strive to have a full outer shell like the noble gases and once they reach their equilibrium, it takes a lot of energy to rip off another electron. Alkali metals, by comparison, have a large atomic radius in their period --> low electronegativity --> low ionization energy. Alkali metals have relatively large atomic radii, which means the nucleus is farther away from the electrons than in an atom with a small atomic radius. Because the electrons are far away, it is easier to rip an electron. If it is easy to take away an electron from an atom, then it has a low ionization energy. Alkali metals have lower first ionization energy than noble gases.
What ions would be most likely to form?
Atoms of alkaline metals: Rb, Cs, Fr, K, Na, Li. They have a low ionization potential. This potential is expressed in kJ/mol - molar ionization energy and is different for the first, second, third...n electron.
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 alkali metals become more reactive the farther you go down on the periodic table?
The ionization energy is lower down in the group.
Which elements are more reactive with oxygen group 1 or group 11?
Elements in group 1 (alkali metals) are typically more reactive with oxygen compared to group 11 (coinage metals). This is because alkali metals have a lower ionization energy and are more likely to form ionic compounds with oxygen.
What groups of metals is the most active?
The alkali metals (Group 1) are the most active metals because they have low ionization energies and readily lose their outer electron to form ions. This reactivity increases as you move down the group due to the decreasing ionization energy.
The Family of what is the most reactive group of metals in the periodic table?
The most reactive group of metals in the periodic table is Group 1, the alkali metals. These metals are highly reactive due to their low ionization energies, which means they readily lose their outermost electron to form positive ions. This reactivity increases as you move down the group due to the decreasing ionization energies.
What are the element within any giving periodic table would always have the lowest first ionization energy?
Elements in the alkali metal group (Group 1) have the lowest first ionization energy within any periodic table. This is because they have a single electron in their outermost shell, which is easier to remove compared to other elements. Sodium and potassium are examples of alkali metals.
How do the reactivity of the alkali metals change in group 1?
The reactivity of alkali metals increases as you move down Group 1 from lithium to francium. This trend is due to the decreasing ionization energy, which makes it easier for the alkali metals to lose their outermost electron and become more reactive.
Which two families in the periodic table have the most reactive metals?
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are the two families in the periodic table with the most reactive metals. Alkali metals are more reactive than alkaline earth metals due to their lower ionization energy and higher reactivity with water and air.
Which group or famil has the lowest ionization energy?
Alkali metals, located in Group 1 of the periodic table, typically have the lowest ionization energy among all the groups. This is because they have only one electron in their outer shell, which is easily removed.
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.
Which group of metals is the most reactive?
Alkali metals are the most reactive group of metals due to their low ionization energy, which allows them to readily lose their outermost electron to form cations. This reactivity increases down the group, with francium being the most reactive alkali metal.
What is the trend for first ionization energy for the alkali metals?
The trend for the first ionization energy of alkali metals decreases as you move down the group from the top. This is due to the increase in atomic size and shielding effect, which allows easier removal of the outermost electron.
