How are Alkaline metals compared to alkali metals?
alkali metals are the "mad" elements who explode when exposed to a certain element. for example, sodium cannot be exposed to hydrogen, or it will explode. on the other hand, alkaline earth metals are good conductors, but they do not explode. they also come only from the earth and its crust.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
Explain why alkali metals have a greater affinity for electrons than alkaline earth metals?
They don't, they actually have a greater tendency to lose electrons. This is for a number of reasons. First of all, the alkali metals form a stable cation by losing one electron, while the alkaline-earth metals need to lose two to form a stable ion. It takes more energy to remove one electron from an atom than it does to remove two. Additionally an alkaline earth metal has a greater positive charge on its nucleus and a smaller atomic radius than an alkali metal in the same row of the periodic table. This make it even harder to remove valence electrons. ------------ ?? WRONG: Alkali metals have a valence electron configuration of ns1 so they can accept another electron in the ns orbital. On the other hand, alkaline earth metals have a valence electron configuration of ns2. Alkaline earth metals have little tendency to accept another electron, as it woudl have to go into a higher energy p orbital.
How many valance electrons do rare earth metals have?
16.546 valence electrons are located in all rare earth elements.
Where are alkali-earth metals located on the periodic table?
Alkali-earth metals are located in Group 2 of the periodic table. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium. They have two valence electrons and exhibit similar chemical properties.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
What are the valece electrons of alkali earth metals?
The alkaline earth metals have 2 valence electrons.
What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
What term describes the reactive nonmetals that have seven valence electrons?
alkali earth metals
What is a family of elements in group 2 with 2 valence electrons?
Alkali-earth metals
How are alkaline earth metals different from alkali metals in terms of their properties and reactivity?
Alkaline earth metals have higher melting points and densities compared to alkali metals. They are less reactive and have two valence electrons, while alkali metals have one valence electron and are more reactive.
How do the alkali metals differ from the alkaline earth metals?
Alkali metals are found in Group 1 of the periodic table and are highly reactive metals with one electron in their outer shell. On the other hand, alkaline earth metals are found in Group 2 and are also reactive but less so than alkali metals, with two electrons in their outer shell. Alkaline earth metals also have higher melting and boiling points compared to alkali 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
Why do the alkaline earth metals react similarly?
All alkali earth metals have two valence electrons and they all form ions in +II oxidation state.
