Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Atoms are mostly filled with?
A
electrons
B
empty space
C
protons
D
None of the above
Explanation: 

Detailed explanation-1: -Because atoms contain electrons with minimal mass, most of the space in an atom is vacant. As a result of containing both neutrons and protons, the nucleus contains all of the atom’s mass. Atoms also have a lot of shells or orbits in which electrons rotate. As a result, the majority of the space in an atom is vacant.

Detailed explanation-2: -Although, by volume, an atom is mostly empty space, dominated by the electron cloud, the dense atomic nucleus, responsible for only 1 part in 10^15 of an atom’s volume, contains  99.95% of an atom’s mass.

Detailed explanation-3: -The electrons are tiny – about 1800 times smaller than the proton, which will represent a pinprick-sized particle buzzing around the grandstand. This is a rough approximation of the distance between the nucleus and electrons and why atoms and therefore everything is mostly empty space.

Detailed explanation-4: -Rutherford carried out a fairly simple calculation to find the size of the nucleus, and found it to be only about 1/100, 000 the size of the atom. The atom was mostly empty space.

Detailed explanation-5: -A hydrogen atom is about 99.9999999999996% empty space. Put another way, if a hydrogen atom were the size of the earth, the proton at its center would be about 200 meters (600 feet) across. While I wouldn’t want something that big landing on my head, it’s tiny compared to the size of the earth.
