When does an atom become an ion with a charge of 2 plus?
Barium has two electrons in its outermost shell, electrons carrying a negative charge. When the Barium atom becomes an ion, these two electrons are lost. Now the Barium atom has more protons than electrons, meaning a net positive charge of 2.
What is the charge on a single atom that has not gained or lost electrons?
Such an atom would be neutral - no electric charge.
What is an atom that has gained or lost electrons and carries an electrical charge?
an ion
Are electrons in group 2 lost or gained?
They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
How is the table of anions and cations?
I didn't understand your question but here I go...An ion is an atom that has lost or gained electrons, and now has a positive or negative charge, respectively.A cation is an ion with a positive charge. An atom that lost electrons and now has less electrons than protons.ANDAn anion is an ion with a negative charge. An atom that gained electrons and now has more electrons than protons.

What is the charge on the tin atom if four electrons have been removed?
The charge on a tin atom that has lost four electrons is 4+.
What is the charge on a single atom that has not gained or lost electrons?
Such an atom would be neutral - no electric charge.
What is the charge on an atom that has lost four electrons?
It will be +4 relative to a proton's charge.
What is an atom that has an electric charge because it lost or gained electrons?
An atom that carries an electrical charge because it has gained or lost electrons is called an "ion". An atom that has gained one or more electrons, and has a negative electrical charge, is called an "anion". An atom that has lost one or more electrons, and has a positive electrical charge, is called a "cation". The term "ion" is used to refer to both cations and anions collectively or non-specifically.

What is it called when a atom that has gained or lost and electron and now has a net electric charge?
When atoms (elements) gain or loose electrons, they become Ions. If an atom looses electrons it becomes +1 charge, whereas if an atom gains electrons it becomes -1 charge.
What are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
What is the charge on an atom of copper that has lost two electrons and how is this ion represented?
+2 is the charge represented Cu2+
