MULTIPLE SELECT QUESTION
45 sec • 1 pt
Which two particles are the largest?
Proton
Neutron
Electron
Answer explanation
The two largest particles among the given options are the proton and the neutron. Both of these particles are found in the nucleus of an atom and are collectively known as nucleons. Electrons, on the other hand, are much smaller and lighter, orbiting the nucleus in electron shells.

Which particle is so small that it's considered massless?
proton
neutron
electron
Answer explanation
The electron is considered massless because it is significantly smaller and lighter than the other particles, such as protons and neutrons. Although electrons do have a small mass, it is so negligible that they are often treated as massless in many calculations and models.

What are the 3 subatomic particles that make up an atom?
Proton
Neutron
Electron
Particles
Answer explanation
The three subatomic particles that make up an atom are protons, neutrons, and electrons. Protons carry a positive charge, neutrons carry no charge, and electrons carry a negative charge. These particles are the fundamental building blocks of atoms, which are the smallest units of a chemical element that retains the properties of that element.

The positive particles of an atom are
electrons
positrons
neutrons
protons
Answer explanation
The question asks about the positive particles in an atom. The correct answer is protons. Protons are positively charged particles located in the nucleus of an atom. Electrons are negatively charged, while neutrons have no charge. Positrons are not typically found in atoms, they are anti-particles of electrons.

The central (middle) region of an atom, where neutrons and protons are located:
Nucleus
Electron cloud
Core
Center
Answer explanation
The central region of an atom, where its neutrons and protons are located, is known as the nucleus. The other options, such as the electron cloud, core, and center, do not accurately describe this specific region of an atom. Therefore, the correct answer to the question is 'Nucleus'.

Particles in an atom that are neutral and have no charge are:
Negatrons
Electrons
Neutrons
Protons
Answer explanation
The question asks about the particles in an atom that are neutral and have no charge. The correct answer is Neutrons. Neutrons are located in the nucleus of an atom and they do not carry any charge, hence they are neutral. Other options like Electrons and Protons carry negative and positive charges respectively, while Negatrons is not a recognized term in atomic structure.

A particle is located outside the nucleus and is the only one that can move around freely...
Proton
Neutron
Electron
Quark
Answer explanation
The question asks about a particle that moves around the nucleus. The correct answer is Electron. Electrons are subatomic particles that orbit the nucleus of an atom. They carry a negative charge and are located in the electron cloud, which is an area surrounding the nucleus. Protons and neutrons, on the other hand, are located inside the nucleus. Quarks are fundamental particles that make up protons and neutrons, but they do not orbit the nucleus.
