A tiny piece of something.
1/60 of a minute is a second.
Density doesn't tell you the mass or the volume. It only tells you what answer you'll get if you divide the mass by the volume. But whether you have a tiny speck of the substance or a super tanker full of it, the density will be the same.
a small or tiny part, amount, or proportion of something
A cubit is a foot and a half.A cubic foot is ... not something that you can compare to a length. It could be a mile square and a tiny fraction of an inch high; it could be miles high and a tiny fraction of an inch square.
A very, very tiny fraction of the two surfaces are eroded.
Ozone layer is the layer. It contains tiny fraction of atmospheric mass.
Yes the thermosphere only contains a tiny fraction of atmospheric mass.
A soap bubble, for example.
No, it is only a tiny fraction. The sun's mass is roughly 330,000 times greater than the Earth.
Yes. If you mean Sagittarius A*, its mass, and even more so its diameter, is only a tiny fraction of the mass, or diameter, of the Milky Way.
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.

The mass of an electron is almost entirely negligible compared to the mass of an atom. I'm not sure if that's the question you were asking, but you can essentially ignore electron mass when calculating the mass of an atom; an electron's mass is only about 0.0005 amu, so even for the heaviest elements the total mass of the electrons is still a tiny fraction of an amu.

No. The galaxy is held together by the mutual gravity of every object in the galaxy. The central black hole accounts for only a tiny fraction of that mass.
No. While the concentration of oxygen in a cloud on Earth is much higher than it is in the sun, the total amount is much lower. A single cloud contains only a tiny portion of Earth's atmosphere, which is itself a tiny fraction of Earth's mass. The sun is about 330,000 times the mass of Earth and is about 1% oxygen, so even at such a low concentration, the mass of oxygen in the sun is about 3,300 times the total mass of Earth.
Most of the mass of the Earth is in the mantle, most of the rest in the core; the part we inhabit is a tiny fraction of the whole
