Front

What is the difference between metals and nonmetals?

Back

Metals are shiny and good conductors of heat and electricity, while nonmetals are dull and generally poor conductors.

Front

Order the following elements by increasing ionization energy: Strontium, Aluminum, Indium.

Back

Strontium < Indium < Aluminum

Front

What is a cation?

Back

A cation is any atom or group of atoms with a positive charge.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from a gaseous atom.

Front

Which element has a larger ionization energy: K or Li?

Back

Li has a larger ionization energy than K.

Front

What are the general properties of metals?

Back

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity.

Front

What are the general properties of nonmetals?

Back

Nonmetals are usually dull, brittle, and poor conductors of heat and electricity.

Front

What is the trend of ionization energy across a period in the periodic table?

Back

Ionization energy generally increases across a period from left to right.

Front

What is the trend of ionization energy down a group in the periodic table?

Back

Ionization energy generally decreases down a group.

Front

Define electronegativity.

Back

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