Which of the following happens when an ionic bond is formed?(1 point)

Responses

One atom pulls an electron from another atom.

One atom becomes more electronegative than another atom.

Two atoms share an electron.

Two atoms attain equal electronegativities.

When an ionic bond is formed, one atom pulls an electron from another atom.

To understand this, we need to know what an ionic bond is. An ionic bond is a type of chemical bond that occurs between atoms when there is a large difference in electronegativities. Electronegativity is a measure of an atom's ability to attract electrons towards itself.

In an ionic bond, one atom has a significantly higher electronegativity than the other atom. As a result, this atom, known as the "more electronegative" atom, pulls an electron away from the other atom, known as the "less electronegative" atom. This transfer of electrons creates charged particles called ions.

The atom that loses an electron becomes positively charged and is called a cation. The atom that gains an electron becomes negatively charged and is called an anion. The opposite charges of the ions attract each other, creating the ionic bond.

So, when an ionic bond is formed, one atom pulls an electron from another atom to achieve a more stable electronic configuration.
