Which statement about the mass of subatomic particles is false?
a)A proton has a mass of 1 amu.
b)A neutron has slightly more mass
than a proton.
C)An electron has slightly less mass
than a proton.
d)none of the above

C

Explanation:

Both proton and neutron have a mass of 1 atomic unit. ( proton positive but neutron no charge) .

even though they both has a mass of 1 amu , they slightly differ in mass. neutron has slightly greater mass than proton .

but electrons are very smaller than protons and neutrons. electron has 1/1840 mass of proton. so they are very smaller than protons.

answer is C

your picture is not part of the scientific method.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
