it neets to loose 2 electrons to have a full outer shell.
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.
When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
Such an atom would be neutral - no electric charge.
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.
An atom that has lost valence electrons is called a cation. This causes the atom to have a positive charge due to having more protons than electrons.

When an atom is no longer neutral and has gained or lost electrons, it is called an ion. An atom that has gained electrons will have a negative charge (an anion), while an atom that has lost electrons will have a positive charge (a cation).
Such an atom would be neutral - no electric charge.
It will be +4 relative to a proton's charge.
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.
An atom that has lost valence electrons is called a cation. This causes the atom to have a positive charge due to having more protons than 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.
Yes, an ion is an atom that has gained or lost electrons, resulting in a net positive or negative charge. This charge is due to the imbalance between the number of protons and electrons in the atom.
This atom become a cation with the electrical charge +2.
an ion
Knowing the charge of an atom only provides information on the number of electrons it has gained or lost. Different types of atoms can have the same charge if they have gained or lost electrons in the same proportion. Therefore, the charge alone is not sufficient to determine the type of atom.
