Imagine you're in a science quiz with Scarlett, Luna, and Mason. The quizmaster asks: 'What do you call a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns?'

• periodic table

• science table

• dinner table

• similar table

Round the mass and subtract the atomic number is how we calculate

• protons

• neutrons

• electrons

• valence electrons
