Final Jeopardy

$100 Question from Scientist

Who were the first to discover the atom?

$100 Answer from Scientist

Greek Philosophers

$200 Question from Scientist

Which scientist stated that the atom was a hard sphere with positive and negative particles spread evenly throughout the surface?

$200 Answer from Scientist

Dalton

$300 Question from Scientist

Use Thomson’s cathode ray experiments to explain why the neutron was the last of the three main subatomic particles to be discovered.

$300 Answer from Scientist

Use the CRT Thomson determined that there the cathode rays were negative but he knew that not all matter was negative so then he determined that there must be a positive charge.

$400 Question from Scientist

Explain the differences between the assumptions that the Greek’s used compares to the assumption Dalton used.

$400 Answer from Scientist

Greek’s did not conduct experiments they used their logic whereas, Dalton used scientific research to further study what the Greek’s proposed.

$500 Question from Scientist

How did Thomson know that the glow in the CRT was from a stream of charged particles?

$500 Answer from Scientist

He knew this because when he placed a magnet near the tube the rays deflected.

$100 Question from Model of the Atom

Why did Rutherford infer that the presence of a tiny nucleus?

$100 Answer from Model of the Atom

When he conducted the experiment some of the particles bouced back from the foil.

$200 Question from Model of the Atom

What particles are in the nucleus of the nuclear atom?

$200 Answer from Doing Science

Protons and neutrons.

$300 Question from Model of the Atom

Which particle found in the atom would not be deflected by a magnet?

$300 Answer from Model of the Atom

A neutron because it does not have a charge.

$400 Question from Model of the Atom

What is difference between atomic number, atomic mass, and mass number?

$400 Answer from Model of the Atom

Atomic number – the number of protons in an atomAtomic Mass – the mass of the protons and neutronsMass Number – the number of protons and neutrons

$500 Question from Model of the Atom

Describe why a neutral atom has the same number of protons and neutrons?

$500 Answer from Model of the Atom

The protons are positive and the elcetrons are negative so in order for an atom to be neutral the atom must have the same number of each.

$100 Question from Nucleus

What are atoms of the same element that have different numbers of neutrons called?

$100 Answer from Nucleus

Isotopes

$200 Question from Nucleus

Which particle have almost the same mass?

$200 Answer from Nucleus

Protons and neutrons

$300 Question from Nucleus

For a radioactive substance , half-life is determined by what?

$300 Answer from Nucleus

The mass of the given substance.

$400 Question from Nucleus

During beta-particle emisson, a neutron splits into what?

$400 Answer from Nucleus

The neutron becomes unstable and splits into an electron and a proton.

$500 Question from Nucleus

Why is iodine-131 a good choice for a trace element?

$500 Answer from Nucleus

Iodine-131 is good as a tracer because it is absorbed easily by cells in the thyroid which transfer through the body.

$200 Answer from Isotopes

2

$300 Question from Isotopes

$300 Answer from Isotopes

1

$400 Question from Isotopes

What is the best description of Dalton’s representation of an atom?

$400 Answer from Isotopes
