Q
What is the structure of the atom?
A
Elements are made of tiny particles of matter called atoms
Each atom is made of subatomic particles called protons, neutrons and electrons
Their size is so tiny that we can’t really compare their masses in conventional units such as kilograms or grams, so a unit called the relative atomic mass is used
