Which series lists particles in order from smallest to greatest mass?

proton, electron, nucleus, atom

electron, proton, nucleus, atom

electron, nucleus, proton, atom

nucleus, electron, proton, atom

The correct answer is B.

The atom is made out of two parts that have the opposite charges, the positively charged nucleus (or the core) made out of protons and the negatively charged electrons that orbit the core.

The electrons, even though they posses the equal amount of electric charge as the protons are significantly smaller than the protons.

Therefore, the smallest particle in this line is the proton, followed by the proton, the nucleus, and in the end, buy the atom, the largest of them.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
