Chemical Bonding: Ionic, Covalent and Metallic Bonds

Eight chapters and 49 lessons, from how ions form to the functional groups of organic molecules. You draw Lewis structures bond by bond on a board that checks every octet, work out the shape and polarity of a molecule from its structure, and mark functional groups on real structural formulas.

Every way to learn

Read, listen, test yourself, ask the AI about your own bench, or look up anything you've already covered. Every lesson meets you where you are.

What Everything Is Made Of
Audio

Everything around you is matter, and all matter is made of tiny particles called atoms.

A substance made of only one kind of atom is an element. There are 118 known elements.

The periodic table lists every element with its symbol: H for hydrogen, O for oxygen.

Why learn chemical bonding with Coddy

  • Lewis structures you draw yourself. Set each bond to single, double or triple and place the lone pairs; the board counts the electrons and names the atom that is short of an octet.
  • Shapes worked out, not memorized. Count the electron groups around the central atom, and the shape, the bond angle and the polarity follow from the structure you drew.
  • From bonds to properties. Electronegativity tells you how polar a bond is, polarity tells you which forces hold molecules together, and those forces explain boiling points and what dissolves in what.
  • Exam-style practice. The last chapter is problems shaped like exam questions, each one a challenge you solve on a board.

Frequently asked questions about chemical bonding

What does the Structure and Bonding section cover?

Ions and ionic compounds, covalent bonds and Lewis structures, the shapes of molecules (VSEPR), bond polarity and electronegativity, polar and non-polar molecules, London forces, dipole forces and hydrogen bonds, metallic bonding and giant covalent structures such as diamond and graphite, and functional groups in carbon compounds, with a final chapter of exam-style practice problems.

What is a chemical bond?

An attraction that holds atoms together. In an ionic bond a metal gives electrons to a non-metal and the ions attract each other; in a covalent bond two non-metal atoms share a pair of electrons; in a metal, positive ions sit in a sea of shared electrons.

How do you draw a Lewis structure?

Add up the valence electrons of every atom, join the atoms with single bonds, give the outer atoms lone pairs until each has eight electrons, and turn lone pairs into double or triple bonds if the central atom is still short. Water has 8 valence electrons: two O-H bonds and two lone pairs on the oxygen.

How long is the Structure and Bonding section?

Eight chapters and 49 lessons, each a few minutes long. Finishing it earns a free, verifiable certificate.

What's the fastest way to learn Structure and Bonding?

Write Structure and Bonding every day. Coddy's course is structured exactly for that: short interactive lessons, immediate exercises, and AI hints when you stall. You spend more time coding Structure and Bonding than waiting on long video lectures.

Do I get a Structure and Bonding certificate when I finish?

Yes. When you complete the Structure and Bonding course you receive a free certificate of completion that you can share on LinkedIn or add to your resume.
