They down in a verticle column. this is representing a family or group of chemicals lol

What do alkali metals have in common with electron shells?
They all have 0NE electron in their outer shell: called s-electron. That's why they belong to group 1
What is characteristic about the outer electron shells of alkali metals?
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
How does the strength of the reaction with water vary as you move down the group of alkali metals?
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
Why are transition metals not as reactive as alkali metals and akaline earth metals?
They are less reactive because they have 2 electrons in the outer shell of the atoms and they like to be full and the alkali metals only have 1 electron in the outer shell of the atom, and it is easyer to give away 1 electron than 2 so they are more reactive than other elements. The electronegativity (Pauling values) is lower for the alkali metals.
What are the families that can lose electrons only from the last shell?
With that wording, the answer would be all of them. If you meant the families that can only lose one electron from their shells, that would be the alkali metals (The left-most column).
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.

Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.

How does the arrangement of alkali earth metals make them very reactive?
Alkalis have one electron in their valency shells. They can "lose" this electron easily, forming a cation which is strongly reactive.
How does the strength of the reaction with water vary as you move down the group of alkali metals?
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
What are the elements called in the first group of the periodic table that have one outer shell electron and is extremely reactive?
The elements in the first group of the period table which have one electron in their outer shells and react extremely well are also known as the alkali metals. These elements are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
Group 1 elements of the periodic table?
Group 1 elements are called alkali metals and all have a single electron in their outer shell/valence shell. These alkali metals are: Lithium (Li) Sodium (Na) Potassium (K) Rb (Rubidium) Caesium (Cs) Francium (Fr)
Why are alkali metals active?
because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.

Group 1A elements have similar properties because they?
have the same number of valence electrons, need the same number of electrons to fill their valence shells
