This question is about atomic structure.

a.

Atoms contain subatomic particles. Table 1 shows properties of two subatomic particles. Complete Table 1:

  • electron: Relative mass = [ ], Relative charge = [ ]
  • [ missing name ]: Relative mass = 1, Relative charge = +1
[2]
b.

Define atomic number.

[1]
c.

An element YYY has two isotopes. Why do these isotopes have the same chemical properties?

[1]
d.

The model of the atom changed as new evidence was discovered. Describe the differences between the nuclear model of the atom and the plum pudding model.
