Questions about the Group 1 poster

What’s on the Group 1 poster?

A 5-row table: Element · With water. Reactivity with water increases down the group. Lithium — Fizzes steadily; Sodium — Melts into a ball, moves rapidly; Potassium — Ignites with a lilac flame; Rubidium — Violent; Caesium — Explosive. All form M⁺ ions and produce hydroxides plus hydrogen: 2M + 2H₂O → 2MOH + H₂.

Who is the Group 1 poster for?

Group 1 belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning inorganic can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Group 1 poster?

One outer electron, further from the nucleus each row, so more easily lost. A wall chart earns its place by being glanceable from where the work is happening, so Group 1 belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Group 1?

Flame Tests, Catalysts and Complex Ions sit alongside Group 1 in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Flame TestsCatalystsComplex Ions

Is the Group 1 poster free to download and print?

Yes. Group 1 downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. 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 Group 1 poster print at?

Group 1 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 Group 1 loses nothing.Printing guide
