Periodic Table Concepts and Ionization Energy

The video tutorial covers a chemistry practice test focusing on the periodic table. It discusses trends in ionization energy, identifying elements in Group 2 and the S block, and understanding electron configurations in the P block. The tutorial also explains how to calculate element properties and charges based on protons and electrons.

Which factor increases the difficulty of removing an electron as you move across a period in the periodic table?

• Increase in atomic radius

• Increase in ionization energy

• Decrease in electron affinity

• Decrease in atomic number

Which element is likely to have a higher first ionization energy, V or Y?

• Both have the same

• Neither

• Y

• V

What is the relationship between ionization energy and the position of an element in the periodic table?

• Ionization energy decreases across a period

• Ionization energy is constant across a period

• Ionization energy increases down a group

• Ionization energy increases across a period

Which element is most likely to be found in group two of the periodic table?

• Neon
