TED-ED: How atoms bond - George Zaidan and Charles Morton

The video tutorial explains how atoms bond with each other, forming either ionic or covalent bonds. Ionic bonds occur when one atom transfers electrons to another, resulting in charged ions that attract each other, as seen in sodium chloride. Covalent bonds involve the sharing of electrons between atoms, forming molecules like proteins and DNA. The arrangement of electrons in an atom determines its bonding capacity, with elements like carbon, nitrogen, and oxygen forming multiple bonds. The video also highlights the varying sizes of molecules, from small oxygen gas molecules to large human chromosomes.

What type of bond is formed when one atom donates an electron to another, resulting in oppositely charged ions?

• Ionic bond

• Hydrogen bond

• Metallic bond

• Covalent bond

Which of the following best describes a covalent bond?

• Atoms share electrons unequally

• Atoms share electrons equally

• Atoms transfer electrons completely

What determines the number of bonds an atom can form?

• The size of the atom

• The arrangement of its electrons

• The number of neutrons in the nucleus

• The number of protons in the nucleus

Which element is most likely to form four covalent bonds?

• Carbon

• Hydrogen

• Nitrogen

• Oxygen

What is a molecule?

• A single atom

• A group of atoms bonded ionically

• A mixture of different elements
