Which family of elements should have the lowest first ionization enegies?
the alkaline metals
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
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.
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 the energy needed to remove electrons from an atom called?
ionization potential energy. but remember the atom must be neutral .
Both Groups IA and IIA have what ionization?
They both have alkaline ionization energies.
Which family of elements should have the lowest first ionization enegies?
the alkaline metals
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
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 water in a water made up of?
Alkaline water has smaller water molecules, which can hydrate the body better than tap water. Alkaline water simply has less H+ and more OH's. This is accomplished through electrolysis or ionization. Waters with more H+ is acidic while water with more OH is alkaline. In nature this ionization happens naturally.
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.
Why ionization energies of alkaline earth metals decrease from Be to Ba?
as we know that there are 7 periods and 18 groups ,as we go down a group the size of the atom decreases therefore there is a decrease in ionization energy for
Why alkaline metals not exist naturally in free state?
Akaline metal do not exist in free state due to high level of ionization energy in them.
What accounts for the general trend in the first ionuization energy of the elements within a period?
As you go from right to left in a period in the periodic table the ionization energy increases. While going from top to bottom in a group in the periodic table the ionization energy decreases .
Why metales have similar molar heat capacity?
because they have free electrons in their outer most shell
Least reactive alkaline earth metal?
All alkali (not alkaline-earth) metals are extremely reactive with water, but within the group, lithium is the least reactive.
Reduce 51 136 to lowest term?
51/136 = 3/8 in its lowsest terms
