What does group 6A elements have compared to group 2A?
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)
When group 2a elements form ions what happens?
Group 2A elements (alkaline earth metals) tend to lose two electrons to form 2+ ions. This is because they have two valence electrons and tend to achieve a stable electron configuration similar to noble gases by losing those two electrons.
Compared with Group 2A elements Group 6A elements have?
Group 6A elements have a higher electronegativity and a greater tendency to gain electrons to achieve a stable octet configuration. In contrast, Group 2A elements have a lower electronegativity and typically lose electrons to form cations.
How group 3A-7A differ from other group A elements?
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.
What elements are in group 2a?
Beryllium, magnesium, calcium, strontium, barium and radium are the group IIA elements.
How many electrons will group 2a lose?
Group 2A elements typically lose 2 electrons when forming ions.
What does group 6A elements have compared to group 2A?

Does group 2A elements lose or gain protons or electrons?
Group 2A elements tend to GAIN electrons!!
How do 1A and 2A differ from the other group A elements?

Does group 2a elements lose two electrons?
