Do alkali metals give or take electrons?
Alkali metals GIVE electrons (the only one electron that they do have) so that they may become balanced.
Why alkali metals give deep blue colour when react with ammonia liquid?
alkali metals give out electrons which is surrounded by ammonia. this is having blue colour
Why alkali metals and alkali earth metals can form cation?
The properties of alkali earth metals and alkaline metals want to give up or share their valence electrons when bonding with a non-metal or polyatomic ion. For example, Sodium (Na) has a single valence electron, and if it bonds with Chlorine (Cl) which has seven valence electrons, Sodium would give up and share it's electron with Chlorine. Because an electron is negatively charged, and a proton, inside the nucleus, is positively charged, the Sodium atom has one less negative charge, and one more positive charge, rendering the ionic charge no longer neutral but +1. This is why metals are able to form cations.
What are physical properties for alkali metals?
Alkali metals are powerful reducing agents, they give up one electron easily. They are extremely reactive.
What alkali metals give off the most electrons?
all alkali metals give off only one electrons. However cesium will give off electron easily. (Francium is not considered generally as it is radioactive with very short half life period).

Alkali metals give ionic hydrides?
yes
What does alkali plus metal give?
Alkalis and metals do not usually react.

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.
What makes alkali metals such good reducing agents?
Alkali metals have one valence electrons. If they will lose these electrons they will attain the electronic configuration of the nearest noble gas and hence form stable cations. Hence alkali metals are good reducing agents (tend to give off electrons).
Give the names of some of the families of elements in the periodic table?
They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.
Can you give an example of a combustion with no flame?
When alkali metals react with water it will explode. Potassium dissolved in water and rubidium and cesium very highly reactive metals dissolved in water will create combustion. Search brainiac alkali metals on youtube.com and see for your self.
Why are alkali metals more reactive than transitional metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
