yes, they can attract each other when one of them is very very large than the other. then, the electrostatic force acting on the two is not due to their initial charges but will be due to the charges produced due to induction and hence attraction takes place.

Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell. Cells can achieve this charge separation by allowing charged ions to flow in and out through the membrane.

Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

When two neutral objects come into contact–especially in a dry environment–electrons can be knocked loose from one object and picked up by the other. Rubbed together in a dry environment, some items have lost electrons and become positively charged, while others have gained electrons and become negatively charged.

In the induction process, a charged object is brought near but not touched to a neutral conducting object. The presence of a charged object near a neutral conductor will force (or induce) electrons within the conductor to move. The flow of electrons results in a permanent charge being left upon the object.

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. Objects with like charge repel each other.

There are two types of electric charge: positive and negative (commonly carried by protons and electrons respectively). Like charges repel each other and unlike charges attract each other. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms.

If a positive number is a deposit to a bank account, then a negative number is a withdrawal from that bank account. If a positive number is a quantity of minutes in the future, then a negative number is a quantity of minutes in the past.

Neutrons

An anion has more electrons than protons, consequently giving it a net negative charge. For an anion to form, one or more electrons must be gained, typically pulled away from other atoms with a weaker affinity for them.

Since the Anode is positively doped, it will attract electrons from the cathode, and this will cause the formation of Anions in its side of the depletion region. The anode is not always the positive lead. It is the electrode through which electric current flows into a polarized electrical device.

An anion is an ion that is negatively charged, and is attracted to the anode (positive electrode) in electrolysis. A cation has a net positive charge, and is attracted to the cathode (negative electrode) during electrolysis.

Key Points

1. The electronic configuration of many ions is that of the closest noble gas to them in the periodic table.
2. An anion is an ion that has gained one or more electrons, acquiring a negative charge.
3. A cation is an ion that has lost one or more electrons, gaining a positive charge.

These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel. When many ions attract each other, they form large, ordered, crystal lattices in which each ion is surrounded by ions of the opposite charge.

Tests for anions

1. dissolve a small sample of the solid salt you are testing in water.
2. place approximately 10cm 3 of the solution into a test tube.
3. add four drops of nitric acid.
4. add silver nitrate solution, dropwise.
5. if a precipitate is produced, observe the colour.

Cations are positive ions that are formed by losing electrons. Negative ions are formed by gaining electrons and are called anions. Anions are designated by their elemental name being altered to end in “-ide”: the anion of chlorine is called chloride, and the anion of sulfur is called sulfide, for example.

Chloride is a halide anion formed when chlorine picks up an electron to form an an anion. It has a role as a human metabolite, an Escherichia coli metabolite and a cofactor. It is a halide anion and a monoatomic chlorine….4.3Related Element.

Please visit the Chlorine element page for information specific to the chemical element of the periodic table….Chlorine cation.

A cation is a positively charged ion with fewer electrons than protons while an anion is negatively charged with more electrons than protons, because of their opposite electric charges; cations and anions attract each other and readily form ionic compounds.

Organic Chemistry The oxygen atom is slightly negatively charged, and the carbon and hydrogen atoms are slightly positively charged. The polar bonds of the hydroxyl group are responsible for the major reaction characteristics of alcohols and phenols.

: the ion in an electrolyzed solution that migrates to the anode broadly : a negatively charged ion.

To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.

Nitrate, chemical formula NO3, has a chemical charge of -1. Ion nitrates have a negative one formal charge.

Anions are negatively charged ions. They are formed when non-metal gains the electrons. They gain one or more than one electron and do not lose any protons. Therefore, they possess a net negative charge. Some examples of anions are Iodide (I–), chlorine (Cl–), hydroxide (OH–).
