The atom, the basic unit of matter, contains even smaller particles. At the center of the atom is a tiny “nucleus”, a core made up of protons and neutrons. Moving around the nucleus in a cloud of possible positions are electrons. Different atoms, and therefore elements, contain different amounts of protons, neutrons and electrons, but retain the same basic structure.

Nov 15, 2014 · An atom contains subatomic particles called protons, neutrons, and electrons. The basic structure of an atom includes a tiny, relatively massive nucleus, containing at least one proton and usually one or more neutrons. Outside of the nucleus are energy levels (also called shells), which contain one or more electrons.

Jun 6, 2018 · There are five basic atomic models which have contributed the structure of the atom itself.

Nov 13, 2015 · What are the names, charges, and locations of the three types of subatomic particles that make up an atom?

Mar 5, 2017 · An atom contains a nucleus in its center with electrons orbiting around it.The nucleus contains protons and neutrons. There is always the same number of protons and electrons in an atom unless its an ion which would contain more electrons or more protons.

Sep 23, 2016 · Up to GCSE it is a very small positive nucleus which has protons and neutrons, surrounded by negative electrons in shells or energy levels around it. Protons have a charge of +1 and a relative mass of 1 Neutrons are neutral (have no charge) and also have a mass of 1 Electrons are negative (have a charge of -1) and have a negligibly small relative mass …

Jun 10, 2017 · An atom of potassium contains PRECISELY 19 protons, 19 massive, positively charged nucular particles. And thus Z, the atomic number, = 19, which specifies the element to be potassium.

Jan 28, 2016 · The massive core of the atom has an opposite electric charge to the electrons, which orbit the atom. The massive nuclear core, the nucleus, contains charged particles, protons, conceived to have a positive charge, and neutrons, conceived to have a neutral charge.

Aug 23, 2017 · There are basically three subatomic particles inside an atom Subatomic particles are those which make up an atom.They are: color (blue) ("Neutron" "It is the neutral part of an atom" "It means that it has no charge.

May 10, 2016 · Atoms are neutral because they have an equal number of protons (+) and electrons (-). Ions are charged particles which are formed when atoms either gain or lose electrons. When atoms gain or lose electrons they become more stable. Here is a review of what happens when ions form.
