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.
