What metals react violently with acid?
All alkali metals (group 1) and most earth-alkali metals (group 2)
Which set of elements make up the reactive group of all metals?
The alkali metals in column 1 of most wide-form periodic tables.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
What side of a periodic table of elements has metallic properties?
the groups of alkali metals, alkaline earth metals, transition metals, and other metal are all metals and some of the metalloids have metallic properties and the alkali, alkaline are on the left, transition metals are in the middle, other metals are located directly next to the transition metals and the metalloids are next to the other metals, and then you have halogens and Nobel gases, Lanthanides and Actinides which are all gases and rare earth.
What order of reactivity NOT activity are the metals Barium Lithium Radium and Sodium in?
The metals listed are all alkali metals or alkali-earth metals. The periodic trend for these groups is: as you move down the group/family, reactivity increases. The alkali metals will be more reactive than the respective alkali-earth metals.Sodium and lithium are alkali metals, so you can organize them first. Sodium is further down in the family than lithium, so we can say that sodium is the most reactive out of the group, followed by lithium. Then we have barium and radium left. Radium is slightly more reactive than barium due to its position, so it is third and barium is fourth.
What metals react violently with acid?
All alkali metals (group 1) and most earth-alkali metals (group 2)
Are alkali earth metals liquids?
no, the alkali metals make up the first period and all of them are highly reactive.
What characteristics are shared by all alkali metals and alkaline earth metals?
They are highly- reactive metals
What is the metal that reacts explosively with acids?
All alkali metals and alkali earth metals below calcium react vigorously with acids.
Metals that are less reactive than alkali metals and alkaline-earth metals are?
Almost all the rest of the metals.
What important characteristics do the alkali metals and earth metals have in common?
They all have at least one electron.
Why alkali metals are more reactive than alkaline earth metals?
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.

Are all types of metals good conductors?
Yes, but alkali and alkaline earth metals have less conductance.
List all the alkali metals?
Lithium Sodium Potassium Rubidium Cesium Francium
Which all metals have low melting and boiling points?
Mercury, all alkali metals (like Sodium) and alkaline-earth metals (like Calcium).
Are oxides soluble?
All oxides are generally insoluble except for oxides of group I metals (alkali earth metals).
