What leads to the formation of an ionic bond with Hg22+? the attraction of a noble gas the attraction of an NH4+ ion the attraction of a group 1 element the attraction of an SO42– ion

The attraction of an SO42- ion leads to the formation of an ionic bond with Hg²+

Explanation:

Ionic bond is formed when there is an electrostatic action in a chemical compound between oppositely charged ions. It is also known as electrovalent bond.

When the outtermost electrons of an atom are transferred to another atom, an ionic bonding is said to have taken place.

In this question, the ionic bonding is formed by the 2 ions ( Hg²+ and SO42). Here, the SO42 ion receive 2 electrons while the Hg²+ ion donates 2 electrons both to achieve the octet rule making ionic bonding to take place.

what leads to the formation of an ionic bond with Hg22+?

the attraction of a noble gas

the attraction of an NH4+ ion

the attraction of a group 1 element

the attraction of an SO42- ion

the attraction of an SO42- ion

Explanation:

Ionic bonding occurs when atoms of element transfer electrons. In ionic bonding, cations and anions are present. One atom lose electrons to form cations in ionic bonding while the other atom(s) gain electrons to form anions in ionic bonding. Ionic bonding usually takes place between a non metal usually the anions and a metal(cations).

In the case of the question the mercury ion, Hg²+ is the cation .The mercury ion has lose 2 electrons while the sulfate ions which is the anion has gain 2 electron . The 2 ions forms ionic bonding easily as Hg²+ donate 2 electron to attain octet rule while the sulfate ion receive 2 electrons also to eventually fulfill the octet rule.
