When it gains an electron. It then becomes a negative ion.
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
It becomes an ion with a larger radius than the atom of chlorine
chlorine have 17 atom the eletron configuration 1s22s22p63s23p5
As the chlorine atom has 17 electrons, the chloride ion has 18.
The chlorine ion is in group 7 so it has a charge of -1.
A chlorine atom becomes a chloride ion when it gains an electron from a metal atom, such as sodium.
It becomes a negative ion.
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
The chloride ion has an electron in plus.
chlorine atom will first convert to the gaseous chlorine atom which will then add one electron to form chloride ion.
It becomes a chloride ion with a 1- charge.
A chlorine ion will have a charge of -1. A chlorine atom gains one electron to form the more stable chloride ion, thereby incurring a charge of -1. There is now one more electron than proton in the chloride ion, as compared to the chlorine atom which is electrically neutral.
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
It becomes a chloride ion with a 1- charge.
chlorine atom has 17 electrons when it accepts one more it becomes chloride ion so chloride has total 18 electrons, isoelectronic with Argon.
The chloride ion is an anion, having one more electron than the chlorine atom.
In the question, it should be either "chlorine atom" or "chloride ion". Chlorine atom has 7 valence electrons. Chloride ion has 8 valence electrons.
