An adult rhino xan have a mass of 1400 kg the mass of a small egret is about 0.76kg. what is the radio of these two masses? how does this ratio compare to the ratio of the mass of a proton ti the mass of an electron?

The ratio of the mass of an adult rhino to the mass of a small egret is

(1400 kg)/(0.76 kg) = 1842.11

The ratio of the mass of a proton to the mass of an electron is

1836.15

The two ratios are very similar, the ratio of the masses of the proton to the electron being slightly smaller.

the answer is c.the valence of the atoms combine .
