Periodic Table Trends

Question 1

What is electronegativity?

Answer 1

Attraction for electrons

Question 2

What is ionization energy

Answer 2

The amount of energy it takes to remove an electron

Question 3

What is atomic radius

Answer 3

The distance between nucleas and outer orbital

Question 4

Does atomic radius increase or decrease down a group?

Answer 4

Increases because there are more occupied energy levels, therefore the attraction between the nucleus and valence electrons is less due to more shielding.

Question 5

Does atomic radius increase or decrease across a period?

Answer 5

Decreases because there is more protons so it can pull the electrons closer to it. Making it a smaller atom (effective nuclear charge)

Question 6

Does ionization energy increase or decrease across a period?

Answer 6

Increases because there are more protons and a greater nuclear charge. Making it harder to remove.

Question 7

Does ionization energy increase or decrease down a group?

Answer 7

Decreases because they’re held on more loosely since they’re farther away from the nucleus.

Question 8

Does electronegativity increase or decrease across a period?

Answer 8

Increases because there are more protons and a greater nuclear charge. Making it harder to remove.

Question 9

Does electronegativity increase or decrease down a group?

Answer 9

Decreases because they’re held on more loosely since they’re farther away from
