Explanation / Answer

True all matters are made up of atom

True The nucleus is the center of an atomIt is made up of nucleons (protons and neutrons) and is surrounded by the electron cloud.

True Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus. The electron cloud has a radius 10,000 times greater than the nucleus.

True The nucleus of an atom consists of protons and neutrons (no electrons)

False A fundamental particle - also known as an elementary particle - is one that cannot be broken into smaller pieces. An atom is not a fundamental particle, because it consists of protons and neutrons in its nucleus and has a cloud of electrons orbiting the nucleus. Protons and neutrons are also not fundamental particles, because they consist of quarks. However, quarks and electrons cannot be broken apart and are fundamental particles.

True Protons and neutrons have almost the same mass, while the electron is approximately 2000 times lighter.

False Protons and neutrons are in the center (nucleus) of the atom.Proton—positive; electron—negative;neutron—no charge
