Lithium, Sodium, Potassium, Rubidium, Caesium, Francium. Some of their properties are they have a low density, are silverish in color, they react with halogens.

They have low density and most of them are in silver colors. They react very well with halogens. Some examples are sodium, potassium, and lithium.

WEll alkali metals are metals in the periodic table. They are lithium, sodium, potassium, rubidium, caesium, francium. The alkali metals react with halogens. And usually have a low density and silver color.

They are different things called Lithium, Potassium, Sodium, Ruvidium, Casesium and Francium. They have some small or low desity, they react with the different hallogens and they have a pretty plain color of silver.

The alkali metals are Lithium, Sodium, Potassium, Runudium, Cesium, and Francium. They do not occur freely in nature. They only have 1 electron in their outer shell. They are softer than most other metals. These alkali metals can explode if they are exposed to water.

Some alkali metals are ithium, sodium, potassium, and rubisium. They have low density and most are silver colors. Alkali metals react well with halogens.

There are 6 alkali metals. They are Lithuim, Sodium, Potassium, Rubidium, Caesium, and Francium. Some of their properties are that they have low density, and are a silverish color, and they also react with halogens.

It has sodium and lithium and they both have some others that are also potassium and francium and they all have a low density and they react with halogens.

The alkila metals are lithium, sodium, potassium, rubidium, caesium, francium. Some of the properties of them are they all have a low density, they are all silverish, and they react well with halogens.

Brandon Erdmann said...

some are low desity they react differently the properities are lithium, sodium, potassium, rubidium, caesium, fracium. they will react with halogens

Alkali Metals are metals like the Alkali Earth Metals but are slightly different in the atomic make up. The Alkali Metals consist of many useful metals that we use everyday but alkali earth metals are rarer and less frequently used in day-to-day life.

Some alkali metals are Lithium, Rubidium, andFrancium. They have a low denisity. The also react with halogens.

*Traci K.* said...

They are found in group 1. They are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, Francium. They have lower densities than other metals. They usually react with nonmetals, especially halogens.

Mal said...

Lithium, sodium, potassium, rubidium, caesium, francium and sometimes Hydrogen are all found in Group 1. They are highly reactive, cant be found in its element stage in natural nature, and tarnish easily. They have a low melting point and a low density. They have an extreme reaction with water.
