It is composed of nuetrons and protons. They are held together by a strong nuclear force which acts against the electron's repulsion force.

Is an atomic nucleus neutrally charged?
No, the atomic nucleus has a positive electrical charge, since it is composed of protons (+) and neutrons (neutral).
What is the atomic mass composed of?
Atomic mass is composed of the mass of protons, neutrons, and electrons within an atom. Protons and neutrons reside in the nucleus of the atom, while electrons orbit around the nucleus. The sum of the masses of protons and neutrons is the primary contributor to the atomic mass.
What are they made up of subatomic particles?
For example the atomic nucleus is composed from neutrons and protons.
What did Rutherford discover about the structure of atoms?
Rutherford discovered the atomic nucleus and the proton.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom.A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
What statement correctly describes part of the atomic model?
electrons are in a cloud outside the nucleus
Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
What Rutherford discovered?

What is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
Who is Rutherford in regards to atoms?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
Most of the mass of an atomic concentrated in the what?
Most of the mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. Electrons, which have a very small mass compared to protons and neutrons, orbit around the nucleus.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
Which atom did the scientist Rutherford discover?
Rutherford discovered the atomic nucleus and the proton. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
