Chlorine has an atomic number of 17 (Z = 17). … We say that that the chloride ion is isoelectronic with
the argon atom
. It is also possible for cations, positively charged ions, to be isoelectronic with the argon atom in its ground state.
Is F isoelectronic with Cl?
Atoms and ions that have
the same electron configuration
are said to be isoelectronic. Examples of isoelectronic species are N

Are Na+ and Cl isoelectronic?
Answer: These species have same number of electrons.
Na+ is isoelectronic with Mg2+
,Ne ,Al3+ no of electrons are 10. An Na+ ion is smaller than an Na atom while a Cl-ion is bigger than a Cl atom.
Is Cl negative isoelectronic?
ClO− is isoelectronic to ClF
. Also, both species contain 26 electrons in all as shown. ClF acts like a Lewis base as it accepts electrons from F to form ClF3.
Are Cl and S2 isoelectronic?
K^ + , Cl^ – , Ca^2 + and S^2 – ions are
isoelectronic
.
Are Al3+ and Cl isoelectronic?
so,
all are isoelectronic species
.
Are K+ and Ca2+ isoelectronic?
Example, sulphide ion (S2− ), chloride ion (Cl−), argon (Ar), and potassium ion (K+ ) are
isoelectronic species
. … The nuclear charge of the Ca2+ion is 20 because calcium ion has a +2 charge. So, the calcium ion has the most charge, hence it will be the smallest and Argon has the least charge so it will be the largest.
Which is isoelectronic with Cl −?
Answer: Some of its isoelectronic species are
S2
– ion (16 + 2 = 18 electrons), Cl– ion (17 + 1 = 18 electrons), K+ ion (19 – 1 = 18 electrons), and Ca2+ ion (20 – 2 = 18 electrons).
Is Na+ isoelectronic with Mg2+?
Na+
, Mg2+, Al3+ and Si4+ are isoelectronic.
Why Na+ is smaller than na?
Na
+
is smaller than Na atom because:
Cations of a given element have a smaller radius than the neutral atom so that
Na
+
will decrease in size compared with the Na atom
. Sodium atoms and sodium ions have the same number of protons. … Sodium-ion has 10 electrons as sodium atom loses one electron to form sodium ion.
Which is isoelectronic with CL negative Mcq?
ClO−
is isoelectronic to ClF.
What neutral molecule is Cl minus isoelectronic?
ClO
–
is isoelectronic to
ClF
. Also, both species contain 26 electrons in all as shown. ClF acts like a Lewis base as it accepts electrons from F to form ClF
3
.
Are K and Cl isoelectronic but their ions radii are not the same?
The two ions have the same electron configuration, which means that they are isoelectronic. … Both ions have their outermost electrons located on the same energy level, but they
do not have the same ionic radius
. That happens because the number of protons each species has in its nucleus varies.
Which of the following is largest in size CL S2 Na+ F?
S
2 –
is the largest in size. S
2 –
and Cl
–
have an extra shell than the other two and thus the two largest ions of the four.
Which is larger k or k+?
When at neutral, the potassium ion in the form of K has an electronic configuration of: … The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence,
K is larger than K+
.
Which is larger Li+ or Mg2+?
Despite the Mg atom having a slightly larger size, the
Mg2+
ion is marginally smaller in size than the Li+ ion because of its higher nuclear charge.
