What’s on the Covalent Bonding poster
A definition and 5 facts worth remembering.
In a covalent bond, two non-metal atoms share a pair of electrons so that both effectively have a full outer shell.
- Each shared pair counts for both atoms.
- Single, double and triple bonds share one, two or three pairs.
- Simple molecular substances have low melting points.
- The bonds inside molecules are strong; the forces between them are weak.
- Most do not conduct electricity — there are no free charges.
- Between — non-metal + non-metal
- Electrons — shared
- Two hydrogen atoms each share one electron, giving both a full first shell.
Melting a covalent substance breaks the weak forces between molecules, not the bonds inside them.

- Who is the Covalent Bonding poster for?
- Covalent Bonding is filed under 10th Grade (ages 15–16), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Covalent Bonding poster?
- Non-metal plus non-metal. Count the electrons each atom needs to fill its shell. A wall chart earns its place by being glanceable from where the work is happening, so Covalent Bonding belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Covalent Bonding?
- Acids and Bases, Balancing Equations and Electron Configuration sit alongside Covalent Bonding in the 10th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Acids and BasesBalancing EquationsElectron Configuration
- Is the Covalent Bonding poster free to download and print?
- Yes. Covalent Bonding downloads as a free PDF with no account, no email and no watermark, like everything else in the 10th Grade set. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Covalent Bonding poster print at?
- Covalent Bonding is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Covalent Bonding loses nothing.Printing guide
