What is an example of a negative ion?
A positive ion is an ion with no negative charges.
Is size of fluorine is smaller than chlorine?
yes F is smaller than Cl due to their electronic configuration. electronic configuration of F is 1s2, 2s2, 2p5 electronic configuration of Cl is 1s2, 2s2, 2p6, 3s2, 3p5
What symbol represents a chlorine ion that has to have a stable electron configuration?
Cl-
Why does ionisation result in a decrease in size for potassium but an increase in chlorine?
Ionization of potassium (K) results in a positive ion, K+, which has the electronic configuration of Ar. The ionization of chlorine (Cl) results in a negative ion (Cl-), also with the electronic configuration of Ar. Adding an electron always increases the size of an atom, and removing one always decreases its size.Note that both K+ and Cl- have the same number of electrons, but Cl- is larger than K+, because they are not as tightly held to the nucleus in Cl- because it has 2 less protons than potassium does. The size of the electron cloud determines the size of the atom and with fewer positively charged protons to pull the same number of electrons in close to the nucleus the electron cloud is larger for Cl-.
Which ion has the same electron configuration as argon?
Cl-, K+, Ca2+ all have [Ar] configuration with 18 electrons (1s2, 2s2 2p6, 3s2 3p6)
What is the electronic structure for a chloride ion 'Cl-'?
The electron configuration of the chloride ion is: [Ne] 1s2.2s2.2p6.3s2.3p6.
Does Cl-1 have a noble gas configuration?
Yes- Cl- has the electronic configuration of argon.
Does element cl have a noble gas electronic configuration?
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
Is Cl a positively charged ion?
No. Chlorine forms a negative ion, Cl-
What is positive ion and negative ion in NACl?
Na is positive ion,Cl is negative ion
Does chlorine form a positive or a negative ion?
Negative ion. Cl-
What is the chloride ion and chlorine atom electron configuration?
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
How does a bond form between sodium and chlorine?
na + cl- na - electronic configuration 2,8,1 cl - electronic configuration 2,8,7 na -e --> na + cl +e -->cl - so they formed a ironic bond between them

What is a noble-gas electron configuration and what is an example of an ion that has this type of configuration?
A noble gas electronic configuration has an outer shell of ns2, np6. Examles of ions with this configuration are O2- [He], 2s2 2p6 (the neon configuartion) Cl- [Ne] 3s2 3p6 (the argon configuration)
What symbol represents a chlorine ion that has to have a stable electron configuration?
Cl-
