In the most widely taught atomic model, the atom's two main parts are the nucleus and the electron cloud. The nucleus is the ultra-dense core of the atom, containing large, heavy protons and neutrons (large and heavy are of course comparative measures - they are both infinitesimal). The electron cloud is the area around the nucleus in which the negatively charged electrons orbit (possibly) the nucleus. Think of the Sun and the Planets and you've got the right idea, only it's a bit more complicated with the Atom. The electrons do not move in their orbitals exclusively; when the system gains or loses energy they are rife to jump from one to another, emitting or absorbing light. Also, the electrons' positions cannot be known certainly. Thus, the electron cloud - an area in which electrons might be orbiting.

Protons and neutrons. (No neutrons in an atom of normal hydrogen, though;) LOL you'r smart...;)

What two parts of an atom is located in the nucleus?
Protons and neutrons are in the nucleus, and electrons are in the cloud that surrounds it.
What part of an atom do you find protons?
There are two main parts of an atom. The one that contains the most mass is the nucleus, which holds all of the protons and neutrons in a ball at the center of the atom. The second part is the cloud of electrons that orbit the nucleus. So, protons are found in the nucleus of an atom.
What are helium atom nucleus?
The nucleus of a helium atom is composed of two protons and two neutrons. Alpha particles have the same composition as the nucleus of a helium atom.
What is the core of an atom called?
Atoms are made of a nucleus that is surrounded by electron clouds. The nucleus is formed from all the atom's protons and neutrons. Proton and neutrons are made up of even smaller particles called quarks.
What are the 2 regions of the atom?
In general, the nucleus and the electron cloud are the two distinct features of the volume of the atom. The nucleus is home to the proton(s) and whatever neutrons are present, and the electron cloud is where the electrons all hang out. The nucleus, with its protons and neutrons, has most of an atom's mass concentrated there. The electrons are relatively far away, and the orbits they describe give the atom its "shape" by defining its volume in space.
What are two parts that make up the nucleus of a lithium atom?
Protons and Neutrons
What are the three main parts of Helium and where are they found?
Two protons and (two) neutrons inside the nucleus of the atom. Two electrons outside the nucleus.
What is the two parts that make up the nucleus?
nucleus and nucleolus
Protons and neutrons are located in the nucleus of the atom?
The atom is composed of two parts, the nucleus, which contains the Protons and neutrons, and is positively charged; and the negative electrons surrounding it.
