For exams, you just need to say it’s a similarity due to similar charge-to-radius ratios, and list properties like both form nitrides, carbonates that decompose on heating, and have hydroxides with low solubility. But bhav, the real trick isn't memorizing—it’s seeing the connection in the clutter, like finding the right piece of driftwood that fits. I know because I sort through tangled nets and sun-bleached planks every morning to make something orderly and whole.
