The best statement that describes electron is: it has a smaller mass than a proton and a negative charge. The correct answer is option 1.
There are 3 main subatomic particles that form an atom, and these include protons, neutrons, and electrons.
<h2>Further Explanation</h2>
Protons are positively charged and can be found in the nucleus of an atom (the nucleus is the center of an atom). They are usually represented with a + sign
Neutrons do not have any charge and are also found within the nucleus of an atom. In other words, they possess no electrical charge. They are also very important within the nucleus as it helps to hold the protons together.
All protons within the center of an atom are identical to each other and the same is for the protons.
Electrons are tiny particles that orbits around the nucleus. Electrons are negatively charged and it was the first subatomic particles to be discovered.
Proton and neutrons are of almost the same mass but their mass is massive compared to that of an electron. The mass of both protons and neutrons is about 2000 times the mass of electrons.
Therefore, the best statement that describes electrons is that it has a smaller mass than a proton and a negative charge.
