A Cl⁻ anion has gained one electron compared to a neutral chlorine atom. A neutral chlorine atom has 7 valence electrons, with the electron configuration of [Ne] 3s² 3p⁵. Therefore, in the Cl⁻ anion, there are 6 electrons in the 3p subshell, as it now has a total of 8 valence electrons (3s² 3p⁶).
Sodium (Na+) with 1 electron in its outer shell, chlorine (Cl-) with 1 extra electron, potassium (K+) with 1 electron removed, calcium (Ca2+) with 2 electrons removed, and argon (Ar) with a full outer shell of electrons.
Al4Cl The compound name is Aluminum Chloride. Al=3- Cl=1+ Chlorine has 7 valence electrons and gains one to become stable making it a positive one charged ion. Aluminum has 3 valence electrons and loses three to become stable making it negative three charged ion.
The chemical formula for sodium chloride (NaCl) indicates that there is one sodium (Na) atom and one chlorine (Cl) atom in each molecule of NaCl. Therefore, the correct numbers of atoms in NaCl are Na1 Cl1.
They all have stable electron configurations, either full outer shells (Argon) or filled electron orbitals (Sodium, Chlorine, Potassium, Calcium). This stability makes them chemically unreactive or less likely to form compounds under normal conditions.
The crossover method for chemistry balances formula units... it's simple once you know how to do it. Here are the steps for the cross over method: Step 1 - In the ionic compounds to be learnt in junior science, there are two parts to the ionic compound - the first is a positive ion (usually a metal e.g. Na1+) and the second is a negative ion (e.g. Cl1-). Step 2 - Using the valency table, write the two ions and their valencies. Step 3 - Now ignore the positive and negative signs. Cross-over the top valency number to the bottom of the other ion symbol. Do this for both. Step 4 - Write the completed formulae with those same numbers at the bottom. Step 5 - If the numbers on each part are the same (e.g. Na1 Cl1 or Mg2 O2), ignore them and rewrite the formulae without them (e.g. Na Cl or Mg O). Step 6 - Brackets may be used around radicals (groups of atoms that are charged e.g CO3). For more information, see Related Links, below.
Chlorine is a non metal element. There are 17 electrons in a single atom.
CaCl2 is an ionic compound. It is formed by the transfer of electrons from calcium (with a +2 charge) to chlorine (with a -1 charge), resulting in the formation of Ca2+ and Cl- ions, which are held together by electrostatic forces.
what is the electron configuration for Cl 1-
An ion with 18 electrons and a charge of -3 would be a chlorine ion (Cl^-). Chlorine normally has 17 electrons, but gaining one electron to form a chloride ion would give it a total of 18 electrons and a charge of -1. To have a charge of -3, two more electrons would need to be gained, resulting in a chloride ion with 18 electrons and a charge of -3.
Na1+ Cl1- + H+1 OH1- = NaOH + HCl
Ionic bonds are formed due to electrostatic force of attraction and Ionic compounds exist as the crystal lattice, (combination of billions of ions), so ionic bond is very strong bond and requires high amount of heat for decomposition.But in water ionic bonds are weak and easily decompose into ions.Example.NaCl ------------ 801 0C----------> Na1+ + Cl1-NaCl--- water + room temp.---->Na1+ + Cl1-
Sodium (Na+) with 1 electron in its outer shell, chlorine (Cl-) with 1 extra electron, potassium (K+) with 1 electron removed, calcium (Ca2+) with 2 electrons removed, and argon (Ar) with a full outer shell of electrons.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
Ionic bonds are bonds formed between one anion and one cation, or in other terms, one metal and one non-metal. One example is NaCl, Sodium Chloride (the common table salt) that is formed between the Na1+ ion and the Cl1- ion. Together they combine and form what is called the ionic compound, bonded together ionically.
They have the same electron configuration as argon, which means they are isoelectronic with argon.
An ion is a charged particle that is formed when an atom gains or loses electrons. The correct ion out of the options you provided is 4. Cl1, which represents a chloride ion that has gained one electron to acquire a negative charge.
CL RATING EX. CL2 is better than CL3 and Cl1 would be the best
