Chem 211 - Lesson 21: Ionic Bonding

Vocabulary flashcards covering key concepts associated with Ionic Bonding, including electronegativity, ion formation, and trends in the periodic table.

Electronegativity (EN)

The ability of an element to attract valence electrons.

Periodic Trends in Electronegativity

Electronegativity increases across a period and decreases down a group.

Cations

Positively charged ions that are named after the element.

Anions

Negatively charged ions where the ending is changed to 'ide'.

Isoelectronic

Having the same electron configuration as a noble gas.

Ionization Energy (IE)

The energy required to remove an electron from an atom.

Main Group Metals

Metals in Groups IA, IIA, and IIIA that tend to lose electrons to form positive ions.

Group IA

Alkali metals, known for easily forming +1 ions due to low ionization energy.

Group IIA

Alkaline earth metals, typically harder and less reactive compared to Group IA.

Group IIIA

Includes elements like Aluminum, which have slightly higher ionization energy than Groups IA and IIA.

Group VI A Nonmetals

Tend to gain electrons to form negatively charged ions.

Group VII A Nonmetals

Tend to gain electrons to achieve a noble gas configuration.

Transition Metals

Elements that can form more than one type of ion, commonly losing different numbers of electrons.
