How is the positive charge of a nucleus related to protons?
It is a whole number of equal positive charges, each associated with a proton.
What is a neutron?
An uncharged particle within the nucleus.
Whose experimental work provided evidence for neutrons?
James Chadwick’s.
When did evidence for neutrons appear relative to the acceptance of the nucleus?
About 20 years after the nucleus became an accepted scientific idea.
What are the size, charge and position of an atom’s nucleus?
It is small and positively charged, at the centre of the atom.
How are electrons arranged around the nucleus in the Bohr model?
