1     Describe the positions of nucleus of an atom.

• inside the central of atom

• outside the nucleus

• inside the neutrons

2. Describe the positions of electrons of an atom.

• inthe central of atom

• outside the nucleus

• inside the nucleus

3. What electrical charge does nucleus carry?

• positive charged (protons) and neutrons (which have no electrical charged)

• Just positive charged

• Electrons and protons

• protons, electrons and neutrons

4. What electrical charge do electrons carry?

• positive charged

• no electricity charged

• negative charged

The diagrams below show atoms losing or gaining electrons. If an atom loses an electron, it becomes smaller. If an atom gains electrons it gets bigger.

Tick one box to show whether electrons are being gained or lost

and show the overall charge it is carrying.

• neutral=> negative, gained

• positive => negative, lost

• negative=> positive, gained

• neutral=> positive, lost

9. What pattern is there in the way that metal atoms?

• gain electron

• lose electron

10. What pattern is there in the way non-metal atoms?
