Which has a higher ionization energy: chlorine (Cl) or magnesium (Mg)? Why? Select the best answer
algol [13]

Removal of the loosely bounded electron is defined by the ionization energy. Chlorine needs less energy to add electrons and has higher ionization power. Thus, option A is correct.

<h3>What is ionization energy?</h3>

The ability of an electron to accept or give electrons to another element in a chemical reaction by forming and creating bonds and the positive and negative charges has been defined by the ionization energy.

Magnesium has lower ionization energy than chlorine due to its large size and smaller nuclear charge. On the other hand, chlorine can easily add electrons to the valence shell which is almost full.

Therefore, option A. chlorine has higher ionization energy and can add electrons with minimum energy.

Write equations to show whether the solubility of either of the following is affected by pH: (b) Hg₂(CN)₂.
nata0808 [166]

<u> Increasing pH will increase the solubility of the Hg2(CN)2 by shifting </u><u>equilibrium </u><u>to right side.</u>

What is the meaning of OH in chemistry?

The chemical group, ion, or radical OH that consists of one atom of hydrogen and one of oxygen and is neutral or negatively charged.

Hg2(CN)2 + 2OH-  ----> 2HgO(s) + 2HCN

adding OH- to the mercury(l) cyanide  will cause the formation of the solid HgO.

therefore increasing pH will increase the solubility of the Hg2(CN)2 by shifting equilibrium to right side.
