Atoms that gain or lose [...] will become electrically charged. | Atoms that gain or lose electrons will become electrically charged. |
An electrically [...] atom has the same number of positive and negative charges. | An electrically neutral atom has the same number of positive and negative charges. |
An atom that carries a charge, either negative or positive, is called an [...]; not an atom. | An atom that carries a charge, either negative or positive, is called an ion; not an atom. |
If an atom has a charge, it's not an atom; it's an [...]. | If an atom has a charge, it's not an atom; it's an ion. |
All atoms have a charge of [...]; otherwise, they'd be called ions. | All atoms have a charge of 0; otherwise, they'd be called ions. |
Positively charged ions are called [?-ions]. | Positively charged ions are called cations. |
Negatively charged ions are called [?-ions]. | Negatively charged ions are called anions. |
Electrons have a charge of [...] each. | Electrons have a charge of -1 each. |
Protons have a charge of [...] each. | Protons have a charge of +1 each. |
Neutrons have a charge of [...] each. | Neutrons have a charge of 0 each. |
An atom that loses one electron has a net electrical charge of [...]. | An atom that loses one electron has a net electrical charge of +1. |
When an atom loses electrons, the net charge goes [...]. | When an atom loses electrons, the net charge goes up. |
When an atom gains electrons, the net charge goes [...]. | When an atom gains electrons, the net charge goes down. |
Subtracting a negative is like adding a [...]. | Subtracting a negative is like adding a positive. |
losing a negative charge is similar to gaining a [...] charge. | losing a negative charge is similar to gaining a positive charge. |
If an atom [...] electrons, it becomes an anion. | If an atom gains electrons, it becomes an anion. |
If an atom [...] electrons, it becomes a cation. | If an atom loses electrons, it becomes a cation. |
Mass number is the number of protons plus the number of neutrons; it has nothing to do with [...]. | Mass number is the number of protons plus the number of neutrons; it has nothing to do with electrons. |
The net charge is the number of [...] minus the number of electrons. | The net charge is the number of protons minus the number of electrons. |
The atomic number is the number of [...]. | The atomic number is the number of protons. |
Mass number minus the number of protons gives you the number of [...]. | Mass number minus the number of protons gives you the number of neutrons. |
Mass number minus the [?-ic] number gives you the number of neutrons. | Mass number minus the atomic number gives you the number of neutrons. |
The atoms of some elements can gain or lose different numbers of [...]. | The atoms of some elements can gain or lose different numbers of electrons. |
Some ions are monatomic ions. Others are [?-atomic] ions. | Some ions are monatomic ions. Others are polyatomic ions. |
Monoatomic ions are [...]-atom ions with a net charge. | Monoatomic ions are single-atom ions with a net charge. |
[...] ions are compounds (or groups of atoms bonded together) that have a net overall charge. | Polyatomic ions are compounds (or groups of atoms bonded together) that have a net overall charge. |
