Positive ions form when an atom or group of atoms loses one or more electrons.
they are ions
metals
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.
They become cations, positive ions.
Non-metals typically become negative ions when they form ions because they gain electrons to achieve a full outer electron shell. This results in a negative charge due to the extra electrons present in the ion.
That is called a cation. They then have a positive charge.
A positive ion, also known as a cation, has a positive nuclear charge. For example, Na+1, Mg+2, and Al+3 are all positive ions, because they tend to give away electrons to have a full eight electrons in its last shell and become stable. O-2, F-1, and I-1 are all anions, negatively charged ions. They tend to gain electrons to have a full eight electrons in its last shell and become stable.
have lost electrons
Cations are electrically positive ions
Positive ions (or cations) - They are reducers.
if it is dipped the zinc electrode looses the electron in to the solution as zinc ions and it attains negative charge on th electrode and it absorb the positive ions in the solution.so w can see a bundle of positive ions just around the zinc electrode
No, metals do not form negative ions: Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals. Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals. A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms. A negative ion (anion) is formed by gaining electron(s) an atom or group of atoms.
