Periodic Table

Front

What is ionization energy?

Back

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

Front

Which element is the most reactive among Potassium, Sodium, Cesium, and Lithium?

Back

Cesium is the most reactive element.

Front

What color on the periodic table corresponds with the transition metals?

Back

Blue corresponds with the transition metals.

Front

Which family of elements does not combine with other elements unless under special conditions?

Back

Noble Gases do not combine with other elements unless under special conditions.

Front

What happens to atomic radius as you move across the periodic table from left to right?

Back

The atomic radius decreases because the number of protons increases, leading to a stronger attraction to electrons.

Front

What are the main groups of the periodic table?

Back

The main groups are Alkali Metals, Alkaline Earth Metals, Transition Metals, Halogens, and Noble Gases.

Front

What is the significance of the atomic number?

Back

The atomic number indicates the number of protons in an atom and determines the element's identity.

Front

What is the difference between metals and nonmetals?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.
