Ion Definition Chemistry Glossary Definition of Ion. An ion is a chemical species that has a greater or lesser number of electrons compared to the number of protons. In other words, it has an electrical charge imbalance.

Ion A cation (+) (/ ˈ k æ t. aɪ. ən /), from the Greek word κάτω (káto), meaning down, is an ion with fewer electrons than protons, giving it a positive charge. There are additional names used for ions with multiple charges. For example, an ion with a −2 charge is known as a dianion and an ion with a +2 charge is known as a dication.

Technology What are Negative Ions? An ion is an electrically charged atom or molecule. Atoms are everywhere and they can be positively or negatively charged – which means they can be positive or negative ions. Positive and negative ions are present in the air all around us.

- Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. When an ion is formed, the number of protons does not change. Neutral atoms can be turned into positively charged ions by removing one or more electrons. A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na + ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.

What is the difference between an atom and an ion? If an atom has the same number of protons and electrons, it is said to be 'neutrally charged' and so has a net charge of zero. An ion, on the other hand, is an atom that has either a negative or a positive charge, and so, has a different number of protons to electrons.

Ion Heating the atom breaks it into two parts (1) a positively charged hydrogen ion, H+ (2) a negatively charged electron. A liquid with ions is called an electrolyte. A gas with lots of ions is called a plasma. When ions move, it is called electricity.

What is the difference between an atom and an ion? If an atom loses an electron, it has one more proton than electron, giving it a net positive charge. An ion with a net positive charge is called a cation. If an atom gains an electron, then it has one more electron than proton, giving it a net negative charge. An ion with a net negative charge is called an anion. Learn more about Atoms & Molecules

Atom If the number of protons and electrons are equal, that atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively, and it is called an ion. The electrons of an atom are attracted to the protons in an atomic nucleus by this electromagnetic force.

- An ion is an atom with an electric charge (positive or negative). A polyatomic ion is a group of atoms with an electric charge. (Even though it is a group of atoms it acts like it were a single atom.). The names of nearly all polyatomic ions end with the letters ate or ite.

What are the differences between ions and isotopes? (December 2007). An ion (/ˈaɪən, -ɒn/) is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization.

- Monatomic Ions. Ions are atoms that have either lost or gained electrons. While atoms are neutral, ions are. charged particles. ø A loss of electrons results in a positive ion or cation (pronounced “cat-eye-on”). ø A gain of electrons results in a negative ion or anion (pronounced “an-eye-on”). Although ions and elements have similar chemical symbols, they are entirely different. substances with different physical properties. A. Monatomic Ions.
