Atoms are made up of three basic parts, which are -

• Protons, neutrons, electrons
• neutrinos, protons, neutrons
• quarks, protons, electrons
• electrons, neutrons, and quarks

Where are the electrons found in an atom?

• In specific orbitals, like planets around the sun
• In a cloud around the nucleus
• in the nucleus
• in a blob of positive matter

We use a model to learn about the atom - Why?

• It is too small to be seen
• Atoms are rare and hard to find
• All atoms are dangerous to work with 
• All of the above

• Thomson
• Dalton

• Rutherford

Which scientist explained that electrons were moving in fixed shells or orbits around the nucleus?

• Dalton
• Thomson
• Rutherford
• Bohr

Which scientist saw the atom as a solid sphere?

• Dalton
• Thomson
• Rutherford
• Bohr

Which scientist saw the atom as mostly empty space with electrons moving around the nucleus? He was the first to find the nucleus.

Scientist of the model of the atom in which the individual atoms are tiny solids like marbles

• Dalton
• Thomson
• Rutherford
• Bohr

One of Dalton's conclusions of his atomic theory was that all atoms of the same element are - 

• Reactive
• different
• combined
• the same
