Group of elements with the same number of valence electrons?
Group I (alkali metals) and group II (earth-alkali metals)
Asked in Chemistry, Periodic Table
Why are Group 1 metals more reactive than Group 2 metals?
Group I metals only have one valence electron, as opposed to the two that Group II has. This means it takes less energy for the alkali metals to release their electron than for the alkaline earth metals to release their two. ...
Asked in Chemical Bonding, Alkali Metals
Why do Alkali metals bond easily?
Alkali metals (Group I) readily lose 1 electron to form positive ions. Compared to alkali earth metals (Group II), alkali metals are more reactive because they only need to lose 1 valence electron to achieve stable electronic configuration. Unlike the metals in Group II, which need to lose 2 electrons. As such, they need to overcome the force exerted by the proton nucleus on 2 electrons instead of just one (for alkali metals). As such, Group II metals have a higher activation...

What group on the periodic table interacts with group 17?
Group 2 of the periodic table interacts with group 17. Group 17 refers to halogen which are highly reactive. Group 2 refers to alkali earth metals which interacts with halogen well enough. ...
Asked in Elements and Compounds
What element would be more reactive than magnesium?
In the context of metals, any element ranked higher in the reactivity series than magnesium would be more reactive. Thus, this includes all other group II metals and all group I metals in the periodic table of elements. Magnesium is the least reactive group II metal. ...
If an atom in group 18 is placed near an atom of group 2 what will usually happen?
Nothing. Group II metals are reactive, but the group 18 or inert gases are not. ...

Asked in Chemistry
Which trend decreases for metals down a group atomic radiusreactivity or melting point?
Melting points generally decrease as you go down a group for group I and group II metals. This does not apply to the transition metals. Reactivity of metals increases down a group due to a larger size and less effective charge between the nucleus and valence electrons. Atomic radius increases due to a higher principle number of electrons. ...
What are the most reactive groups in the periodic table?
The most reactive group in the periodic table is none other than Group 1. Group 1 refers to alkali metals. ...
What is the difference between the alkali metals and the alkaline earth metals?
1.Both are differ in valency shell electrons 2.I-A are monovalent and II-A are divalent 3.I-A is more reactive then the II-A group . 4.I-A have more electro positive character and II-A have less electro positive character than the I-A group . 5.I-A have less ionization energy and II-A have high ionization energy than the I-A . 6.I-A have very less electro negativity than the II-A group elements. 7.I-A is soluble in water and II-A is insoluble in water . 8.I-A metals are does not react directly...
