what are the two components which make up an atom ?

The atom consists of three particles:
Protons (with a positive charge), neutrons, (with no charge), and electrons, with a negative charge.
The protons and neutrons are together and form the nucleous. Because the protons are +ve and the neutrons are neutral, the nucelous has an overall positive charge. This means that the negatively charged electrons are attracted to it. The electrons spin around the nucleous, held in place by the attractive forces.
There are usually the same numbers of electrons and protons in atoms, to balance out the charge.
If an atom looses or gains an electron, it becomes charged, (+vely charged if it looses electrons, or -vely charged if it gains electrons). These charged particles are known as ions, and when an atom becomes an ion it is said to be ionised.

The atom is made up of a central nucleus and this is surrounded by a cloud of moving elecetron. But, inside the nucleus there are protons and neutrons. To be honest all questions about atomic structure ask about the 3 particles inside an atom. protons, neutrons and electrons.

The nucleus of an atom is made up of protons and neutrons. The outer shell of an atom is electrons.
Protons and neutrons can also each be broken down into 3 quarks

The nucleus and the electron cloud. The Nucleus is composed of proton and nuetrons.

nucleus and electron cloud
in the nucleus there are protons and neutrons
