- Stored under oil because they react with air.
- Sodium and potassium fizz and burn in water.
- They form ions with a +1 charge.

- Who is the Alkali Metals poster for?
- Alkali Metals is filed under 8th Grade (ages 13–14), 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 Alkali Metals poster?
- Find the group on the table. Everything in the column behaves this way. A wall chart earns its place by being glanceable from where the work is happening, so Alkali Metals belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Alkali Metals?
- Alkaline Earth Metals, Halogens and Noble Gases sit alongside Alkali Metals in the 8th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Alkaline Earth MetalsHalogensNoble Gases
- Is the Alkali Metals poster free to download and print?
- Yes. Alkali Metals downloads as a free PDF with no account, no email and no watermark, like everything else in the 8th 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 Alkali Metals poster print at?
- Alkali Metals 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 Alkali Metals loses nothing.Printing guide
