Is lithium behaves different from the other alkali metals true or false?
True. Although lithium is an alkali metal it is quite different from the other alkali metals. In fact it can generally behave more like an alkaline earth metal, such as Magnesium (Mg), Calcium (Ca) Strontium (Sr) and Barium (Ba). One of the major characteristics of the alkali metals is their low ionization energy, which is why lithium can easily be present in its ionic form of Li+. However, lithium posses the highest ionization energy of the alkali metals
Sodium an alkali metal and chlorine a halogen are both in Period 3 of the periodic table Which element has a higher ionization energy?
Chlorine has a higher ionization energy. Chlorine's tendency is to gain electrons, not lose them as metals usually do.
Alkali metals cannot be used in voltaic cells?
Lithium is an alkali metal and is used in the highest energy capacity cells made.
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
It decreases as the atom radius gets larger, so it decreases from top to bottom.
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 is ionization suppressor?
An ionization suppressor is a salt of an alkali metal added to suppress ionization of an analyte. The alkali metal is easily ionized resulting in a flux of electrons which shift the ionization equilibrium of analyte towards formation of atoms.
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
What is the energy released during ionization of a non metal?
ionization energy
Sodium an alkali metal and chlorine a halogen are both in Period 3 of the periodic table Which element has a higher ionization energy?
Chlorine has a higher ionization energy. Chlorine's tendency is to gain electrons, not lose them as metals usually do.
Alkali metals cannot be used in voltaic cells?
Lithium is an alkali metal and is used in the highest energy capacity cells made.
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.
The energy released during the ionization of a non-metal is called the?
ionization energy
What happens to the ionization energy as you go down the periodic table in the nonmetal side?
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
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
It decreases as the atom radius gets larger, so it decreases from top to bottom.
Why alkali metal have low ionization energy?
Ionization energy is the energy required to remove an electron from an atom or ion. Low ionization energy indicates that it takes less energy to remove an electron from the atom. The alkali metals are in Group I on the Periodic Table. This indicates that their atoms have only one electron (out of a possible eight) in their outermost energy level. Therefore it takes less energy to remove the single outermost electron. Moving across a period on the Periodic Table, ionization energies increase because there are more and more electrons in the outermost energy level, requiring more energy to remove an 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.
