What are the parts of an atom?
Structure of an atom
Nucleus - center or core which contains protons and neutrons
Proton is a positively (+) charged particle in the nucleus
Neutron is neutral. It has no charge.
Electrons are very tiny particle that surround the nucleus and is negatively (-) charged
Thomson's model - first scientist to suggest an atom contains smaller particles. He discovered the negatively charged electrons.
Rutherford's model - discovered that the atom is mostly empty space and the protons are in the nucleus
Bohr's model - discovered that the electrons are arranged in different energy levels.
Modern model is based on the finding of Thomson, Rutherford, and Bohr. It states that the location of the electrons cannot be known because they form a cloud around the nucleus

Most atoms are composed of three types of subatomic particles which govern their external properties:
electrons, which have a negative charge and are the least massive of the three;
protons, which have a positive charge and are about 1836 times more massive than electrons; and
neutrons, which have no charge and are about 1839 times more massive than electrons.
Protons and neutrons make up a dense, massive atomic nucleus, and are collectively called nucleons. The electrons form the much larger electron cloud surrounding the nucleus.

Everyone is right, proton neutron electron.
around the nucleus at a ratio of 2:8:8.
2 protons nearest nucleus
up to 8 neutrons
up to 8 electrons
i.e. 1 proton only in the atom is H (hydrogen).
you can work out what the structure is from the atomic number on a periodic table.

Protons and Neutron are found inside the nucleus of an atom. Electrons orbit the outside of a nucleus.
Get all three together, along with the nucleus and you have an atom.
Hope this helps.

Are we doing your homework for you? Why not google this?
In any event, the answer you seek is proton, neutron and electron. But of course these break down into smaller sub atomic particle. I think quarks.

Proton, neutron, and electron. Although those are actually made up of subatomic particles themselves. Maybe they are made up of forces....

protons, which are positively charged
electrons-which are negatively charged
neutrons-which are neutral and have no charge
an atom always has the same number of protons as electrons, if it looses or gains an electron it becomes a charged ion, and if it changes it's proton number it becomes a different substance

A proton, electron ,and neutron. A neutron and proton are inside the nucleus , and and electron is outside of it
