Isoelectronic species are those which contains same no of electron Ar=18 e– Cl- also contains 18 e S-² K+ Ca+² Students (upto class 10+2) preparing for All Government Exams, CBSE Board Exam, ICSE Board Exam, State Board Exam, JEE (Mains+Advance) and NEET can ask questions from any subject and get quick answers by subject teachers/ … Options (a) CIO₃⁻,CO₃²⁻ (b) SO₃²⁻,NO₃⁻ (c) CIO₃⁻,SO₃²⁻ (d) CO₃²⁻,SO₃²⁻ Correct Answer: CIO₃⁻,SO₃²⁻ Explanation: ClO₃⁻ and SO₃⁻ ² both have same number of electrons (42) and central atom in each being sp³ hybridised. Threshold frequency, ν 0 is the minimum frequency which a photon must possess to eject an electron from a metal. See more. It is different for different metals. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. (a) F, cr (6) K, Ar Cselect) isoelectronic. Which of the following atoms and ions are iso electronic(i.e have the same number of electrons) with a neon atom: C , O 2 − , N − , F + , Na + , Al 3 + A . P 3-, S 2-, Cl-, Ar, K +, Ca 2+, Sc 3+ This series each have 18 electrons. Draw a complete line-bond or electron-dot formula for acetic acid and then decide which statement is incorrect. Isoelectronic Series. For example : Isoelectronic Ions: Let us consider ions "A" which has the same number of electrons as ions "B", then the two ions are said to be Isolectronic ions. Q:-In a reaction A + B2 → AB2 Identify the limiting reagent, if any, in the following reaction mixtures. (e) 11 lone pairs, no bonds, and 5 bonds. Isoelectronicity is an effect observed when distinct molecular entities have identical electron configurations. Write the general outer electronic configuration of s-, p-, d- and f- block elements. A positive charge means the shortage of an electron. Isoelectronic are the species having same number of electrons. The first one IS NOT isoelectronic since these atoms are in different periods. Which of the following pairs of ions are isoelectronic and isostructural . Answer the following questions and then press 'Submit' to get your score. Isostructural chemical compounds have similar chemical structures.Isoelectronic terms refer to two atom, ions or molecules that have the same number of valence electrons.ClO3- = SO32- Number of electronsCO32- = 6+2+24 =32SO32- = 16+2+24 = 32ClO32- = 17+24+1 = 42NO32- = 7+2+24 = 33Hence ClO32- and SO32- are isoelectronic and are pyramidal in shape. For example : Two or more molecular entities (atoms, molecules, ions) are described as being isoelectronic[1] with each other if they have the same number of valence electrons and the same structure (number and connectivity of atoms), regardless of the nature of the elements involvedN and the O+ ion are isoelectronic because each has one atom and 5 electrons in the outer electronic shell.
