When an atom loses an electron, the atom has a [...] charge and is called a cation. | When an atom loses an electron, the atom has a positive charge and is called a cation. |
A positively charged ion is called a [...]. | A positively charged ion is called a cation. |
You can remember that a cation is positive because the [...]. | You can remember that a cation is positive because the 't' in 'cation' looks like the + sign. |
In an atom, the valence electrons are those in the [...-most] orbitals. | In an atom, the valence electrons are those in the outermost orbitals. |
[...] electrons are the ones that participate in forming ions. | Valence electrons are the ones that participate in forming ions. |
When an atom gains an electron, the atom has a [...] charge and is called an anion. | When an atom gains an electron, the atom has a negative charge and is called an anion. |
A negatively charged ion is called an [...]. | A negatively charged ion is called an anion. |
An ion formed from a single atom is called a [...-atomic] ion. | An ion formed from a single atom is called a monoatomic ion. |
For most metals, the charge of an ion will be the same as the [...] number in a periodic table labeled 1A, 2A, etc. | For most metals, the charge of an ion will be the same as the group (column) number in a periodic table labeled 1A, 2A, etc. |
Charges on [...] metal ions are harder to predict. | Charges on transition metal ions are harder to predict. |
