Nearly all the volume occupied by matter consists of __________________.?

Question

A. electrons
B. protons
C. neutrons
D. nothing

Answer 1

nothing
if you would scale the size of a core to the size of a tennisball
the radius with witch the electron rotates around the core would be 1 kilometer (2/3 miles)


most of the mass consists of
neutrons and protons
(the core of an atom)
an electron is like a 1000 times lighter then an proton or a neutron
so most matter consists of protons and neutrons
but most mass is found in the core

if you need to pick one
then i go for neutrons
u= 1 atomic mass until = 1.6602*10^-24g
proton: 0.007277u
neutron: 0.008665u
and electron: 0.000548u

so an neutron is heaviest
so neutrons take a little bit more room then protons :)

Answer 2

Well it definitely not D unless you ignore quantum mechanics.

In any meaningful sense it is A. The electron probability density is above zero almost everywhere in matter, so there are no empty spaces and most spaces are at least partly filled with electrons.

But I bet lots of people say D because they do not understand this.

Answer 3

D) nothing

The atom has a dimension of 10^-10m , the nucleus 10^-15m

Answer 4

D) Nothing (just empty space)

Answer 5

D. nothing

Answer 6

nothing
