What is the shape of a trigonal planar molecule?

Back

A trigonal planar molecule has a flat, triangular shape with bond angles of 120 degrees.

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 electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals.

Front

What is the significance of bond strength in chemistry?

Back
