FAC- Ionic Bonding

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

What happens to valence electrons in ionic bonding?

Back

In ionic bonding, metals lose valence electrons to form positive ions (cations), while nonmetals gain valence electrons to form negative ions (anions).

Front

What charge do alkali metals (Group 1A) have when they form ions?

Back

Alkali metals form ions with a charge of 1+.

Front

What charge do halogens (Group 7A) have when they form ions?

Back

Halogens form ions with a charge of 1-.

Front

How many valence electrons does sulfur (S) gain when forming an ionic bond?

Back

Sulfur gains 2 valence electrons when forming an ionic bond.

Front

How many valence electrons does beryllium (Be) lose when forming an ionic bond?

Back

Beryllium loses 2 valence electrons when forming an ionic bond.

Front

What is the role of electronegativity in ionic bonding?

Back

Electronegativity is the tendency of an atom to attract electrons. In ionic bonding, a metal with low electronegativity transfers electrons to a nonmetal with high electronegativity.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.
