What is ionization energy?

Back

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

Front

Which element has a higher ionization energy than Calcium (Ca)?

Back

Beryllium (Be) has a higher ionization energy than Calcium (Ca).

Front

What does the hypothesis of Continental Drift state?

Back

The hypothesis of Continental Drift states that continents once formed a single landmass, broke up, and drifted to their present locations.

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases have the smallest atomic radius.

Front

What happens to ionization energy as you move across the periodic table from left to right?

Back

Ionization energy increases as you move from left to right across the periodic table.

Front

What are Alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive.

Front

What are Halogens?

Back

Halogens are the elements in Group 17 of the periodic table, known for their reactivity and tendency to form salts.

Front

What is the significance of the atomic radius?

Back

The atomic radius is a measure of the size of an atom, which affects its reactivity and bonding.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius decreases, ionization energy increases.

Front

What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras.
