Ions having same number of electrons are called isoelectronic ions.
Give example of 2 cations and 2 anions which are isoelectronic with argon.

Ions having same number of electrons are called isoelectronic ions. Out of Na^+ and Ne which has higher ionisation enthalpy. Explain why?

K^+ and Ca^(2+) are isoelectronic with Argon. Out of Na^+ and Na which has smaller size and why?

The ions of NaF and MgO have the same number of electrons and internuclear distances are also about the same ( 235 pm and 215 pm ). Then why the melting points of NaF and MgO are different ( 992^circ C. and 2642^circ C resp.)

K^+ and Ca^(2+) are isoelectronic with Argon. Explain what is isoelectronic ions.

Write the electronic configuraiton of Mg 2+ ion

Which of the following statements regarding the movement of ions in a cell is/are correct? (1) Cations move towards cathode and anions towards anode in both galvanic and electroytic cells. (2) Cations move towards cathode and anions towards anode in an electroytic cell and the reverse is true for a galavanic cell (3) Cations move towards cathode and anions towards anode in a galvanic cell and the reverse-is true for an electrolytic cell (4) Cations move towards anode and anions towards cathode in a galvanic cell and the reverse is true 'for an electrolytic cell

Predict the number of unpaired electrons in the squar planar [Pt(CN)_4]^(2-) ion.

Assertion: The ionic size of O^(2-) is bigger than that of F^(-) ion. Reason: The O^(2-) and F^(-) are isoelectronic ions.
