Front

How are ionic bonds formed?

Back

Transfer of electrons

Front

If you have an oxyacid and it contains an -ate polyatomic ion, then the acid's ending will change to _____.

Back

-ic

Front

Determine the molecular geometry of a structure with a central atom bonded to three other atoms and one lone pair.

Back

Trigonal Pyramidal

Front

If you have a binary acid and it contains an -ide monatomic ion, then the acid's name will change to _____.

Back

hydro-root-ic acid

Front

What is the definition of a chemical bond?

Back

A lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a polyatomic ion?

Back

An ion composed of two or more atoms bonded together, that carries a charge.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion theory predicts the geometry of molecules based on electron pair repulsion.

Front

What is the significance of the octet rule in bonding?

Back

Atoms tend to bond in a way that gives them eight valence electrons, achieving a stable electron configuration.
