The atom is the smallest particle of a substance 1 of 16 Is it true that an atom can be split into simpler substances? Why or How? An atom cannot be split into simpler substances because it is the simplest particle 2 of 16 What is the center of an atom called? The center of an atom is called the nucleus. 3 of 16 Atoms consist of a nucleus however what does this nucleus contain? Atoms consist of a central nucleus containing protons and neutrons surrounded by orbiting electrons. 4 of 16 In a chemical reaction are atoms able to be rearranged? In a chemical reaction atoms can be rearranged 5 of 16 In a chemical reaction can new atoms be produced or can atoms be destroyed? In a chemical reaction new atoms cannot be produced nor can atoms be destroyed 6 of 16 Is it true that everything is built up from atoms or built up from compounds? Everything is built up from atoms 7 of 16 What are atoms made up of? Atoms are made up of protons, neutrons and electrons. 8 of 16 Atoms can combine to make a bigger particle. What is this called? Atoms can combine to make a bigger particle called a molecule. 9 of 16 What is the electrical charges of the proton in the atom? The electrical charges of the proton in the atom is +1 10 of 16 What is the electrical charges of the neutron in the atom? The electrical charges of the neutron in the atom is 0 11 of 16 What is the electrical charges of the electron in the atom? The electrical charges of the electron in the atom is -1 12 of 16 What does this tell us about the electrical charges? Atoms have no overall electrical charge 13 of 16 Why is this? Atoms have no overall electrical charge as the electric charges balances making it neutral overall 14 of 16 What happens when you remove an electron from an atom? When you remove an electron from an atom it makes positive ions 15 of 16 What happens when you add an electron to an atom? When you add electrons to an atom it creates negative ions 16 of 16
