What to do? Design a PowerPoint presentation on Nuclear Radiation

 

With each slide

  • include images
  • highlight the important terms/ phrases in each dot point 

You may copy and paste the points from this page!

 

Slide1: Title: Nuclear Radiation

 

Slide 2: Describe the nuclear model of the atom?

  • Atoms are made up of a positively charged nucleus.
  • The nucleus is the centre of an atom and contains most of the mass.
  • The nucleus consists of protons and neutrons. (Highlighted to stand out. You do the rest)
  • Negatively charged electrons orbit the nucleus of an atom.
  • Atoms are made up of mostly empty space.

 

Slide 3: Describe the role of three sub atomic particles found in an atom

  • The number of protons determines the identity of an element. This is called Atomic Number
  • Neutrons help stablise the nucleus.
  • Electrons are involved in chemical reactions

 

Slide 4: What are isotopes?

Isotopes are atoms of an element that have a different number of neutrons.

 

Slide 5: Describe the isotopes of the element Carbon

  • All Carbon atoms have 6 protons.
  • Isotopes have a different number of neutrons.
  • Carbon-12 has 6 neutrons
  • Carbon-13 has 7 neutrons
  • Carbon-14 has 8 neutrons

 

Slide 6. What are radioisotopes?

  • Radioisotopes are atoms of elements that emit nuclear radiation.
  • Radioisotopes have an unstable nucleus. 
  • Radioisotopes have too few or too many neutrons in the nucleus or the nucleus is just too big.
  • Carbon-14 has an unstable nucleus. It emits radiation and is called a radioisotope.

 

Slide 7: How can nuclear radiation be detected?

Nuclear radiation can be detected by

  • a Geiger Muller tube attached to a counter
  • photographic film
  • a cloud chamber

 

Slide 8: What are three types of nuclear radiation?

Alpha decay

Beta decay

Gamma decay

 

Slide 9: What is an alpha particle?

An alpha particle is a postively charged particle that is emited from the nucleus of an atom.

 

Slide 10: What is a beta particle?

A beta particle is a high energy electron that is emiited from the nucleus of an atom

 

Slide 11: What is gamma radiation

Gamma radiation is high energy electromagnetic radiation.
