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 electron configuration of Cl1?
what is the electron configuration for Cl 1-
What is calcium's electron configurations?
The element calcium, or Ca, is located in group 2, period 4 of the Periodic Table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
What is the ground-state electron configuration of the chloride ion Cl?
Chloride anion Cl- has the same electron configuration as Argon (its succeding noble gas) so:Cl- has 18 electrons configured like: 1s2, 2s2 2p6, 3s23p6
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 ions has the same electron configuration of a noble gas ca or ci?
Cl- and Ca2+ has the electronic configuration of the noble gas, Ar, with 18 electrons.
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 electron configuration of Cl1?
what is the electron configuration for Cl 1-
Does F and Cl elements have the same valence electron configuration?
yes
What is the electron configuration for cl?
2,8,7
When an ion and an atom are isoelectronic?
Answering by example: Cl- ion, Ar atom, K+ and Ca2+ ions are all 'iso-electronic' to each other, because they all have the same 20 electrons in the same (noble gas) electron configuration (structure) as argon has: [Ar] = [1s2, 2s2 2p6, 3s2 3p6]
What is calcium's electron configurations?
The element calcium, or Ca, is located in group 2, period 4 of the Periodic Table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
What the correct electron configuration for chlorine?
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
What is the ground-state electron configuration of the chloride ion Cl?
Chloride anion Cl- has the same electron configuration as Argon (its succeding noble gas) so:Cl- has 18 electrons configured like: 1s2, 2s2 2p6, 3s23p6
What is the noble gas electron configuration of sodium chloride?
In NaCl, there exists Na+ and Cl- ions and with the electron configuration of [He]2s22p6 (for Na+) and [Ne]3s23p6 (for Cl-)

Electron Configuration of Chlorine-35 the same or different as Chlorine-37?
They're the same, they both have 17 protons and 17 electrons. The only difference is that Cl-35 has 18 neutrons, whereas Cl-37 has 20. Both have the electron configuration of [Ne] 2s2 3p5
