What element is in period 4 group 2A?
The element in period 4 group 2A is calcium (Ca).
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.
What type of ion is formed by group 2A elements?
Cat-ion
If X is an element in Group 2A and Y is an element in Group 7A what would be correct about the compound that would form between X and Y?
They would form an ionic compound.
What group is magnesia in?
Magnesia is not an element but magnesium is in group 2A
What electric charge is characteristic for an ion of Ba?
Barium (Ba) will typically have a +2 charge as it is a group 2A element.
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)
What is the symbol of the element is period 4 and group 2a?
The symbol of the element in period 4 and group 2A is Ca, which stands for Calcium. It is a reactive alkaline earth metal with atomic number 20.
Suppose an element x is in group 2a and an element y is in group 7a the empirical formula for the compound between x and y?
The empirical formula for the compound between x and y would be xy. Since x is in group 2a and y is in group 7a, their charges would be 2+ and 7-, respectively. To balance the charges, one x would combine with three y to form the compound with the formula XY3.
What s block element is not located in group 1A or group 2A in the periodic table?
One example of a block element that is not located in group 1A or group 2A in the periodic table is carbon, which is a p-block element. Carbon is located in group 4A (14) of the periodic table and is known for its diverse bonding properties, forming a wide range of compounds.
What element is in 2a period 3?
The element in the 3rd period and 2nd group of the periodic table is magnesium (Mg).
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
