Chapter 6 Exam

Front

What is the definition of Ionization Energy (I.E)?

Back

Ionization Energy (I.E) is the amount of energy required to remove an electron from a gaseous atom.

Front

Which electron in Magnesium requires the most energy to remove?

Back

The 3rd electron.

Front

What trend occurs in ionization energy as you move down a group in the periodic table?

Back

Ionization energy decreases.

Front

Which elements belong to the same group in the periodic table: He, Ne, Ar or H, Li, Na?

Back

He, Ne, Ar belong to the same group.

Front

What is an anion?

Back

An anion is a negatively charged ion that forms when an atom gains one or more electrons.

Front

What happens to the size of an ion when it gains electrons?

Back

The ion becomes larger.

Front

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

Back

Ionization energy increases across a period.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy generally decreases.

Front

What is the significance of the periodic table in understanding ionization energy?

Back

The periodic table helps predict trends in ionization energy based on an element's position.

Front

How does the removal of electrons affect the charge of an atom?

Back

Removing electrons results in a positive charge, forming a cation.
