Difference Between Chlorine Atom and Chloride Ion

(i) Chlorine atom has 7 electrons in its M shell while Chloride ion has 8 electrons in the same shell. (ii) Chlorine atom is neutral while chloride ion is negatively charged. (iii) Chlorine atom is highly reactive while its ion is inert. iv) Chlorine gas is poisonous while chloride ion is non-poisonous.

Why chlorine atom is different from chloride ion?

Every atom needs 8 electrons in its outermost shell except for a few like hydrogen, helium etc. Here, chlorine needs one more electron to complete its last shell and become stable. ... When this happens chlorine will become a chloride ion because now it has some charge on it.

Is chlorine an ion or atom?

Since it has 1 more electron than protons, chlorine has a charge of −1, making it a negative ion. When ions form, atoms gain or lose electrons until their outer energy level is full.

Is chloride ion bigger than chlorine atom?

Chlorine has a proton number of 17. ... Hence, we can deduce that the forces of attraction exerted on the outermost electron in chloride ion is lesser than chlorine atom, since there are more electrons. Conclusion, chloride ion has a bigger atomic radius due to an increase in number of electrons.

What happens to make a chlorine atom become a chloride ion?

For a chlorine atom to become a chloride ion, it must gain an electron. The chloride ion has a negative charge and is written as Cl-. Chlorine gains an electron because it has seven valence electrons, and to be a full octet, it gains an electron. A chloride ion is called an anion.

Is chloride a salt?

The chloride ion is the most common form of chlorine and is one of the two elements that make up table salt, a.k.a. sodium chloride (NaCl). We use table salt to make food taste better and as a preservative. NaCl and other chloride-containing salts (MgCl2, CaCl2, etc.)

What is difference between atom and ion?

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.

Why does an atom become an ion?

When a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they become ions and form NaCl.

What must be true if an atom is ionized?

A stable atom has a net charge of 0. In other words, it has an equal number of protons and electrons. The positive protons cancel out the negative electrons. When the number of electrons does not equal the number of protons, the atom is ionized.

Why potassium ion is smaller than chloride ion?

In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.

Is potassium bigger than chlorine?

The potassium atom (K) is larger than the chlorine atom (Cl), but the potassium ion (K+) is smaller than the chlorine ion (Cl-).

Is Br or Br bigger?

Br - will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
