Electronegativity of negatively charged atom Simply put, negative charges prefer to rest on more electronegative elements (see here for more on electronegativity) than on more electropositive elements (like carbon). That's why water is more acidic than ammonia (NH 3), because oxygen is more electronegative than nitrogen. If the charge in an organic ion is formally centred on a carbon, it is termed a carbocation (if positively charged) or carbanion (if negatively charged). Formation Formation of monatomic ions. Monatomic ions are formed by the gain or loss of electrons to the valence shell (the outer-most electron shell) in an atom.
An ion is an atom or group of atoms where the number of electrons is not equal to the number of protons. Electrons have a negative charge, whereas protons have a positive charge. When an atom gains electrons, this results in a negative charge. This type of ion is called an anion. When an atom loses electrons, this results in a positive charge. A positively charged ion is called a cation. Let's explore several ion examples of both types.
Examples of Positive Ions
Positive ions are typically metals or act like metals. Many common materials contain these ions. Mercury is found in thermometers, for instance, and aluminum is a metal that is found in a surprising amount of things. It's even an ingredient in baking soda and in certain other food products!
The positive charge (more protons versus electrons) for a cation is shown by a number and plus sign after the formula. If there's just a plus sign, it means the charge is plus 1. Some examples of cations, or positive ions, include the following:
- Aluminum - Al+3
- Barium - Ba+2
- Bismuth - Bi+3
- Cadmium - Cd+2
- Calcium - Ca+2
- Cesium - Cs+
- Chromium (III) - Cr+3
- Cobalt - Co+2
- Copper (I) - Cu+
- Copper (II) - Cu+2
- Hydrogen - H+
- Iron (II) - Fe+2
- Iron (III) - Fe+3
- Lead (II) - Pb+2
- Lithium - Li+
- Magnesium - Mg+2
- Mercury (I) - Hg2+2
- Mercury (II) - Hg+2
- Nickel - Ni+2
- Potassium - K+
- Rubidium - Rb+
- Silver - Ag+
- Sodium - Na+
- Strontium - Sr+2
- Tin (II) - Sn+2
- Zinc - Zn+2
Examples of Negative Ions
Just as atoms can lose electrons to become cations, some can gain electrons and become negatively charged anions. Again, you may be familiar with some of these ions. Fluoride is sometimes added to community water supplies. Your dentist may also give you a flouride treatment.
The negative charge (fewer protons than electrons) for an anion is shown by a number and minus sign after the formula. If there's just a minus sign, it means the charge is minus 1. Here are several examples of anions:
- Bromide - Br-
- Chloride - Cl-
- Fluoride - F-
- Iodide - I-
- Nitride - N3-
- Oxide - O2-
- Sulfide - S2-
Polyatomic Cations and Anions
If an ion consists of two or more atoms it is called a polyatomic ion. Just like their single-atom counterparts, they too can gain and lose electrons.
Polyatomic Cations
Ions with multiple atoms that lose electrons, and are thus positively charged, are called polyatomic cations.
- Ammonium - NH+4
- Hydronium - H3O+
Polyatomic Anions
Ions with multiple atoms that gain electrons, and are thus negatively charged, are called polyatomic anions. In the list below, the charge has been put in parentheses for ease of legibility, but standard notation calls for the charge to be written as a superscript instead.
- Acetate - CH3COO- or C2H3O2-
- Arsenate - AsO43-
- Bicarbonate or hydrogen carbonate - HCO3-

Fully Charged Reaction
When you study chemistry, you will encounter many examples of ions, as well as the different types of ions and how they interact and relate to each other. For more on the topic, be sure to explore some examples of chemical bonds and examples of chemical properties. Perhaps they'll be the catalyst for positive change in your learning experience!
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Most of an atom’s mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. Although the nucleus is heavy, it is quite small compared with the overall size of an atom.
The radius of a typical atom is around 1 to 2.5 angstroms (Å), whereas the radius of a nucleus is about 10-5 Å. If an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium. The nucleus of an atom contains protons and neutrons. Protons and neutrons have nearly equal masses, but they differ in charge. A neutron has no charge, whereas a proton has a positive charge that exactly balances the negative charge on an electron. Table (PageIndex{1}) lists the charges of these three fundamental particles, and gives their masses expressed in atomic mass units.
Negatively Charged Atoms Are Called
Particle | Charge | Mass (amu) |
---|---|---|
Electrons | -1 | 0.000549 |
Protons | +1 | 1.00782 |
Neutrons | 0 | 1.00867 |
The atomic mass unit (amu) is defined as exactly one-twelfth the mass of a carbon atom that has six protons and six neutrons in its nucleus. With this scale, protons and neutrons have masses that are close to, but not precisely, 1 u each (there are 6.022 x 1023 u in 1 gram This number is known as Avogadro’s number, N, and one of the ways this number can be calculated is discussed below). The number of protons in the nucleus of an atom is known as the atomic number, Z. It is equal to the number of electrons around the nucleus, because an atom is electrically neutral. The mass number of an atom is equal to the total number of heavy particles: protons and neutrons.
When two atoms are close enough to combine chemically--to form chemical bonds with one another—each atom primarily “sees” the outermost electrons of the other atom. These outer electrons are therefore the most important factors in the chemical behavior of atoms. Neutrons in the nucleus have little effect on chemical behavior, and the protons are significant only because they determine how many electrons surround the nucleus in a neutral atom.
All atoms with the same atomic number behave in much the same way chemically, and are classified as the same chemical element. Each element has its own name and a one- or two-letter symbol (usually derived from the element’s English or Latin name). For example, the symbol for carbon is C, and the symbol for calcium is Ca. The symbol for sodium is Na-the first two letters of its Latin (and German) name, natrium,to distinguish it from nitrogen, N, and sulfur, S.
Example (PageIndex{1}): Bromine

Solution
Positively Or Negatively Charged Atom
Bromine’s atomic number is 35, and its symbol is Br; B is the symbol for boron
