Elements in Group 2 of the Periodic Table form ions with a charge of 2. This group includes elements such as calcium, magnesium, and barium. When these elements lose two electrons, they form ions with a +2 charge.
Elements having 2 valence electrons form ion with a charge of 2.
and the elements which need two electrons to complete its octet form ion with -2 charge.
Oxygen forms oxide, also sulfur, selenium and tellurium form 2 minus charge ions

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-
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 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 for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
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?
Calcium forms an ion with the same charge as the sulfate ion, which is 2-. This ion is written as Ca2+.
What charge would an ion have based on its group?
An ion's charge can be determined by its group number on the periodic table. Group 1 elements form ions with a +1 charge, group 2 elements form ions with a +2 charge, group 13 elements can have a +3 charge, and so on. Group 17 elements typically form ions with a -1 charge.
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-.
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.
Which group on the periodic table loses 2 electrons to create an ion?
Group 2 metals typically lose 2 electrons to form ions with a +2 charge. This group includes elements such as magnesium (Mg) and calcium (Ca).
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 charge does Sr form when it forms and ion?
strontium is a metal, therefore it must form only positive ions.
What is the ion charge on sulphate?
The ion charge on sulfate is 2-. This means that the sulfate ion carries a charge of -2.
Indicate the number of electrons lost or gained by calcium and give the charge of the ion it forms?
Calcium loses 2 electrons to achieve a full octet, forming a Ca2+ ion with a 2+ charge.
What is the charge of chromate ion?
The chromate ion has a charge of 2-.
What possible charge can lead acquire as an ion?
Lead can form ions with a charge of +2 or +4.
