BTEC Chemistry Fundamentals Worksheet
Help the science team investigate an unknown substance. Read each clue carefully, choose or write your answers, and use your knowledge of particles to support your explanations. Follow laboratory safety rules throughout.
Atoms and elements
Use what you know about particles and the periodic table.
1.A science team models a carbon atom. Which particles are found in its nucleus?
- Protons and neutrons
- Protons and electrons
- Neutrons and electrons
- Electrons only
2.A neutral atom has 11 protons. How many electrons does it have, and what is its atomic number?
3.Most metals are found on which part of the periodic table?
- The left and centre
- The far right only
- The top row only
- Outside the periodic table
Substances and reactions
