There are six elements in group 2A
A group is a vertical column. The group consists of Be , Mg, Ca ,Sr, Ba , and Ra.
Group 2A elements form compounds that are less soluble in water. Group 2A elements are harder. Group 2A elements have an additional valence electron. Group 2A elements are less reactive.
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
Do you own CA work!!
Beryllium, magnesium, calcium, strontium, barium and radium are the group IIA elements.
Group 2A * Known as Alkaline earth elements * All are metals * Occur only in compounds * React with oxygen in the general formula EO (where O is oxygen and E is Group 2A element)
Group 2A elements tend to GAIN electrons!!
