What else can I help you with?
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.
What is the effect of heat energy on alkali metals?
The melting point of alkali metals is low.
How many electrons occupy the highest energy sublevel of alkali metals?
One electron occupies the highest energy sublevel of alkali metals. Alkali metals have one electron in their outermost energy level, making them highly reactive.
Why are alkaline earth metals harder than alkali metals?
i thought increase in size.
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 is the relationship between ionization energy and the alkali metals?
There is no relation ship. They have the lowest ionization energies.
Does alkali metals have a full outer energy level?
No, they don't.
Hydrogen is grouped with alkali metals because it?
Hydrogen is grouped with alkali metals because it has similar chemical properties, such as having one electron in its outer shell and being reactive. However, hydrogen is not a true alkali metal as it does not readily form a cation with a 1+ charge like the alkali metals do.
Which group metals are very reactive with one electron in the outer energy level?
Alkali metals
What is the name of metals with two electrons in the outer energy level?
You think probable to alkali earth metals.
Why do alkali metals have lower ionization energies than the alkali 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.
What is the group trend for the ionization energy for the alkali metals?
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
