You probably already took this but if anyone wanted to know the answer it's D. "A system where matter and energy cannot enter or leave the system".

<u>Both given statements are true.</u> An atom has a nucleus, an electron cloud, and subatomic particles.
There are two main parts of an atom i.e. nucleus (protons + neutrons) and the electron cloud which is composed of three subatomic particles: electrons, protons, and neutrons.
An electron is a subatomic particle having a negative charge on it.
While protons are positively charged particles and are found in the nucleus of an atom due to strong nuclear forces.
On the other hand, a neutron, as the name suggests, is a neutral subatomic particle having no charge at all.
