Periodic Trends

Question 1

Moving left 🡢 Right across the periodic table (atomic radius)

Answer 1

Decreases because Adding e- pulls electrons in tighter

Question 2

Moving down 🡣 the periodic table (atomic radius)

Answer 2

Increases because it gains energy levels

Question 3

Ionization Energy

Answer 3

The amount of energy required to remove an e-

Question 4

From left 🡢 Right (Ionization Energy)

Answer 4

Increases, because adding protons increases the e- attraction to the nucleus making it harder to remove e-

Question 5

Moving down 🡣 (Ionization energy)

Answer 5

Decrease, Ve- move farther from the nucleus as energy levels are added making it easier to remove e-

Question 6

The most reactive metal

Answer 6

Fr, the bigger the atomic radius the easier it will be to remove an e-

Question 7

The most reactive nonmetal

Answer 7

F, it is easier to gain an e- with a small atom
