The Arrangement of Electrons and Atomic Bonding

The video tutorial explains the structure of atoms, focusing on the arrangement of electrons in energy levels. It details how electrons are organized in these levels and the capacity of each level. The tutorial also highlights the importance of valence electrons in determining how atoms bond with each other to achieve stability.

What are the three main components of an atom?

• Protons, neutrons, and positrons

• Neutrons, electrons, and quarks

• Protons, electrons, and photons

• Protons, neutrons, and electrons

How many electrons can the first energy level hold?

• Two

• Thirty-two

• Eight

• Eighteen

What is the maximum number of electrons the second energy level can accommodate?

• Eight

• Ten

• Eighteen

• Two

What are electrons in the outermost energy level called?

• Valence electrons

• Free electrons

• Core electrons

• Bonding electrons

Why do atoms tend to bond with other atoms?

• To decrease their energy levels

• To change their atomic number

• To complete their outermost energy levels

• To increase their mass
