Typically, a negative ion is formed by gaining electrons. This is because electrons hvae a negative charge. An example of a case where a positive ion can be formed by gaining an electron is when an ion with a charge of +2 can gain 1 electron and become +1. Technically in this case, a positive ion was formed when an electron was gained but the trend was that the ion became more negative not positive.
A positive ion is formed when an atom loses one or more then electrons.
The ion hydronium is (H3O)+.
The positive ion lost an electron.
A negative ion (anion) is formed after gain of electrons in the atom.A positive ion (cation) is formed after loss of electrons from the atom.
If the atom has lost electrons then it would have formed a positive ion, if it has gained electrons it would be a negative ion.
To make an atom into a positive or negative ion, it loses or gains any number of electrons.Positive ions or cations are formed when atoms lose electronsNegative ion or anions are formed when atoms gain electrons
If an atom gives one or more electrons as a result positive ion is formed. The reason is that an electron is negatively charged and normally an atom is neutral. if it gives electrons then positive ion is formed which is more likely to take electron to become neutral.
It would be a SALT
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
A cation i.e positive ion is formed when atoms loses an electron. As no. of proton and electron are equal in neutral atom. As electron is removed the proton becomes greater in no. So a positive ion is formed.
Either positive or negative for an ion, or neutral for a "free radical" or other molecule.
A negative ion (anion) is the result of gaining electrons. A positive ion (cation) is the result of losing electrons.
An ion is formed when an atom gains or loses an electron in bonding with another atom, causing the atom to become a positive or negative ion.
no it forms a positive ion
When a neutral atom loses electrons, it forms an ion with a positive charge. The atom has more protons than electrons which causes the positive charge. A cation is an ion with a positive charge.
There are ionic compounds which is a compound formed by a positive metal ion and a negative nonmetal ion. And there are convalent compounds which is a compound formed in which atoms share electrons.
A positive ion with a single charge and a "free" electron are formed.
An ion with missing electrons, and thus a positive charge, is a cation.
a negative ion
An ion is formed. A positive ion if there are fewer electrons than protons. A negative ion if there are more electrons than protons.
An ionic bond. The ions form a lattice of positive and negative ions which is overall charge neutral, the charges balance out.
