Unit 3 Ionic Bonding Metallic Bonding

Front

What is ionic bonding?

Back

Ionic bonding is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of cations and anions that are held together by electrostatic forces.

Front

What are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What are anions?

Back

Anions are negatively charged ions that are formed when an atom gains one or more electrons.

Front

What is the role of opposite charges in ionic bonding?

Back

Opposite charges attract each other, which is the fundamental principle that brings cations and anions together in ionic bonding.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that represents the valence electrons of atoms within a molecule, showing how they are arranged and bonded.

Front

What is metallic bonding?

Back

Metallic bonding is a type of chemical bonding that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing metals to conduct electricity.

Front

What is the 'sea of electrons'?

Back

The 'sea of electrons' refers to the delocalized electrons in metallic bonding that are not bound to any specific atom, allowing for conductivity and malleability.

Front

How do you determine the number of atoms in a chemical formula?

Back

The number of atoms in a chemical formula is determined by the subscripts present in the formula; for example, in Al2O3, there are 2 aluminum (Al) atoms and 3 oxygen (O) atoms.

Front

What is the difference between ionic and covalent bonding?

Back

Ionic bonding involves the transfer of electrons and the formation of charged ions, while covalent bonding involves the sharing of electrons between atoms.

Front

What is a chemical formula?

Back

A chemical formula is a symbolic representation of a compound that shows the elements present and the ratio of their atoms.
