Answer:

a.Cathode rays have mass.

b.They are subatomic size particles in an atom.

d. Matter contains negative charge and by inference positive charge.

e. Particles of the cathode rays are fundamental to all matter.

Explanation:

The statements above reflect the Thompson model of the atom. Electrons were first known as cathode rays. The Thompson's model viewed the atom as a sphere of negative charges into which positive charges were embedded. This is the plum pudding model of the atom.

What is the radius of a hydrogen atom whose electron is bound by 0.544 ev? express your answer with the appropriate units?
insens350 [35]
First, we need to calculate the principal quantum number n for this electron, using the equation:
E = (-13.60 eV) / (n x n)
where E is the energy that is used to bound the electron (here, E = - 0.544 eV).
- 0.544 eV = (-13.60 eV) / (n x n)
n x n = (- 13.60 eV) / (- 0.544 eV)
n x n = 25
n = 5

The orbital radius that is equal to the radius of a hydrogen atom is calculated using the equation:
r = 0.053 nm x n x n
r = 0.053 nm x 5 x 5
r = 0.053 nm x 25
r = 1.325 nm
