What’s on the Alkaline Earth Metals poster
A definition and 5 facts worth remembering.
Reactive metals, but noticeably less so than group 1 — they hold their two outer electrons more tightly.
- Two electrons in the outer shell.
- Harder and denser than the alkali metals.
- Form ions with a +2 charge.
- Calcium is in bones; magnesium is in chlorophyll.
- Reactivity also increases going down.
- Group — Group 2
- Members — Be, Mg, Ca
- Be · Mg · Ca · Sr · Ba · Ra
Elements in the same group share outer-electron counts, which is why they behave alike.

- Who is the Alkaline Earth Metals poster for?
- Alkaline Earth 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 Alkaline Earth 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 Alkaline Earth Metals belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Alkaline Earth Metals?
- Alkali Metals, Halogens and Noble Gases sit alongside Alkaline Earth 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.Alkali MetalsHalogensNoble Gases
- Is the Alkaline Earth Metals poster free to download and print?
- Yes. Alkaline Earth 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 Alkaline Earth Metals poster print at?
- Alkaline Earth 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 Alkaline Earth Metals loses nothing.Printing guide
