C1 Lessons 1-12

What is an atom?

• The smallest part of an element that can still be recognised as that element

• A substance made of only one type of atom

• A substance made of two or more different atoms chemically bonded together

• A substance made of more than one atom chemically bonded together (can be atoms of the same type!)

What is an element?

• The smallest part of an element that can still be recognised as that element

• A substance made of only one type of atom

• A substance made of two or more different atoms chemically bonded together

• A substance made of more than one atom chemically bonded together (can be atoms of the same type!)

What is a compound?

• A substance made of only one type of atom

• A substance made of two or more different atoms chemically bonded together

• A substance made of more than one atom chemically bonded together (can be atoms of the same type!)

• A substance made of more than one thing not chemically bonded together

What is a molecule?

• A substance made of only one type of atom

• A substance made of two or more different atoms chemically bonded together

• A substance made of more than one atom chemically bonded together (can be atoms of the same type!)

• A substance made of more than one thing not chemically bonded together

What is a mixture?

• A substance made of only one type of atom

• A substance made of two or more different atoms chemically bonded together

Name the three subatomic particles

• Protons, quarks, electrons

• Protons, neutrons, electrons

• Borons, neutrons, electrons

• Protein, neutral, electricity

State the masses of the subatomic particles

• Protons: 1, neutrons: 0, electrons: 1

• Protons: 0, neutrons: 1, electrons: 0

• Protons: 1, neutrons: 1, electrons: 1

• Protons: 1, neutrons: 1, electrons: 0

How are the subatomic particles arranged in an atom?

• Protons and neutrons in the nucleus, electrons orbiting in shells

• Neutrons and electrons in the nucleus, protons orbiting in shells

• Electrons and neutrons in the nucleus, protons orbiting in shells

• Protons in the nucleus, electrons orbiting in shells

What is the plum pudding model of the atom?

• A ball, similar to a snooker ball.

• A ball of negative charge with positive protons embedded into it.

• A central mass of positive charge with negative electrons orbiting in shells.

• A ball of positive charge with negative electrons embedded into it

What did the gold foil experiment prove?

• That atoms have a dense nucleus with a neutral charge.

• That atoms have a dense nucleus with a positive charge.

• That atoms have a do not have a nucleus.

• That atoms have a dense nucleus with a positive and negative charge.
