Atoms become positive ions when they lose an electron in a reaction. An electron is negative and a proton is positive, so when the atom loses an electron it will have more positive than negative, and the atom will be a positive ion. The atoms at the left of the Periodic Table usually lose electrons in reactions.
That's correct! When atoms gain or lose electrons, they become ions with an overall positive or negative charge. Positive ions are called cations, and negative ions are called anions.
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
Atoms that are neutral in charge have the same quantity of protons and electrons. Negative ions have extra electrons, and positive ions are missing electrons.
Positively charged ions, or cations, are atoms that have lost electrons, resulting in a net positive charge. Negatively charged ions, or anions, are atoms that have gained electrons, leading to a net negative charge. These charged ions are formed through the process of ionization.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Positive ions (or cations) are formed when atoms lose electrons
Positive ions
That's correct! When atoms gain or lose electrons, they become ions with an overall positive or negative charge. Positive ions are called cations, and negative ions are called anions.
A polyatomic ion is a group of atoms with a charge.
Positive ions form when an atom or group of atoms loses one or more electrons.
Yes, if they are ions
have lost electrons
metals
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
Metals form positive ions because they lose electrons.
Because they want to.
Atoms are neutral. Ions can be charged, either positive or negative.
