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 3 – , O 2 – , F – , Ne, Na + , Mg 2 + , and Al 3 + (1s 2 2s 2 2p 6 ). Another isoelectronic series is P 3 – , S 2 – , Cl – , Ar, K + , Ca 2 + , and Sc 3 + ([Ne]3s 2 3p 6 ).
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.
