When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
What 2a elements pick up a 2 charge when they form an ion?
Yes: 2+ charge by loosing 2 electrons (when oxidized) Me --> Me2+ + 2e-
What period 3 diatomic elements will form ions with a negative 2 charge?
Only chlorine has a diatomic molecule biut any ion is 2-..
What is the electron charge of zinc?
the charge of zinc has only one charge which is 2+.
What is the charge of the element magnessium?
Elements have no charge. It is when an atom loses or gains electrons to complete its outer shell that it becomes an ionand has a charge. In Magnesium's case, its ion has a charge of 2+

The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
What 2a elements pick up a 2 charge when they form an ion?
Yes: 2+ charge by loosing 2 electrons (when oxidized) Me --> Me2+ + 2e-
Which element forms an ion with the same charge as the sulfate ion?
The sulfate ion is SO42-. Elements in group 16 form anions with a charge of 2-, for example oxygen forms the oxide, O2- anion.
How can you predict that oxygen will form an O2- ion and not an O3- ion?
All of the elements in column six of the periodic table have a 2- charge
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
When group 2a elements form ions what happens?
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
Indicate the number of electrons lost or gained by calcium and give the charge of the ion it forms?
loses 2 electrons to form a calcium ion with 2+ charge
What period 3 diatomic elements will form ions with a negative 2 charge?
Only chlorine has a diatomic molecule biut any ion is 2-..
What kind of ion does magnesium form?
Mg ^ 2+ :D
What the charge for Nickel atom?
Nickel has an atomic number of 28- so if there aare only 26 electrons - 2 are missing and the ion will have a harge of 2+.
What is the total charge of beryllium?
Beryllium the element (Be) has a zero charge. Beryllium the ion (Be^2+) as a plus 2 charge.
What is the charge of Mg?
Mg or the element magnesium has only one possible charge of +2. Just a hint but all elements in group 2 have a charge of +2 ie. Be, Ca, Sr...
