Periodic Table Properties

Front

What is ionization energy?

Back

Ionization energy is the amount of energy required to remove an electron from an atom in its gaseous state.

Front

Which element has a higher ionization energy than arsenic (As)?

Back

Neon (Ne) has a higher ionization energy than arsenic (As).

Front

How does ionization energy change as you move down a group in the periodic table?

Back

Ionization energy decreases as you go down a group in the periodic table.

Front

What group in the periodic table contains inert (unreactive) elements?

Back

Group 18 contains inert (unreactive) elements.

Front

What are the two classifications of matter?

Back

Matter can be classified as either a Pure Substance or a Mixture.

Front

What type of element is Silicon?

Back

Silicon is classified as a metalloid.

Front

What is the general 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 are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of Group 18 elements in the periodic table?

Back

Group 18 elements are known as noble gases and are characterized by having a full valence shell, making them very stable and unreactive.

Front

What is a pure substance?

Back

A pure substance is a material that has a constant composition and consistent properties throughout.
