Alkaline Earth Metals
Group 2A elements tend to GAIN electrons!!
The entire Group 2A has 2 valence electrons; this includes sodium and calcium.
Two valence electrons.
This group, as all groups, shares similar interaction dynamics with other elements because this group, group 2A, has two valance electrons in the outer shell.
Halogens
These are the alkaline-earth metals.
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!!
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.
There are six elements in group 2A A group is a vertical column. The group consists of Be , Mg, Ca ,Sr, Ba , and Ra.
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!!
Group 2A elements are commonly known as the alkaline earth metals, while groups 1A is called the alkali metals.
Beryllium, magnesium, calcium, strontium, barium and radium are the group IIA elements.
