If you want to find out whether an atom contains positive ions or negative ions, you will generally need to look it up. However, there are some general rules that can help you figure it out without research.
First of all, there are 3 types of elements on the periodic table: metals, nonmetals, and metalloids. The majority of elements are metallic. Atoms tend to form ions based on whether they gain or give away electrons (e-) when bonding with other elements.
Nonmetals tend to form anions (negative ions), meaning that they gain 1 or more electrons when forming a bond. Metals, on the other hand, tend to lose electrons when bonding, so they are most likely to form cations (positive ions).
You can tell if an atom will form a positive or negative ion if the number of electrons (which have a negative charge) is greater then the number of protons (which have a positive charge), or visa versa.
If there are more electrons, the atom will form a negative ion, but if the atom has more protons, the atom will form a positive ion.
ions with a negative charge have more electrons. and ions with positive ions have less ions than originally had.
If the atom loses its electrons , then it possesses a positive charge and form a cation.
It is a positive ion. Its' charge is 3+.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
Negative charge: electrons Positive charge: protons

An ion may have either a positive charge or a negative charge. So there term "positive ion" simply tells which of the two general types it belongs to.
It depends on what ion it is. If it is a cation, then the ion has a positive charge and an anion has a negative charge.
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
An ion is an atom with a positive or negative charge.
It is a positive ion. Its' charge is 3+.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
Zinc ion (cation) is positive.
An ion is either a positive charged or a negative charged atom. Negative ions have one or more extra electrons, and positive ones have one or more electrons not there.
A negative charge attracts a positive charge and repels a negative charge. OPPOSITES ATTRACT ;)
An Ion.
either negative or positive charge always
It is a positive ion. Its' charge is 3+.
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
