How are protons electrons and neutrons related to atoms?

Answer 1

Atoms all have a similar structure - they have a nucleus surrounded by one or more electrons. Each nucleus is made of protons and neutrons. All atoms of a particular element all have the same number of protons and electrons, and usually have the same number of neutrons too (although sometimes these differ) in all their atoms. Different elements have different amounts of these fundamental particles in their atoms. The first few elements (in terms of numbers of protons starting with 1, 2 3 etc) have numbers of protons, neutrons and electrons as follows: Hydrogen: 1 proton and 0 neutrons in the nucleus and 1 electron in orbit around it. Helium: 2 protons and 2 neutrons in the nucleus and 2 electrons in orbit around it. Lithium: 3 protons and 4 neutrons in the nucleus and 3 electrons in orbit around it. Beryllium: 4 protons and 5 neutrons in the nucleus and 4 electrons in orbit around it. Boron: 5 protons and 5 neutrons in the nucleus and 5 electrons in orbit around it. Carbon: 6 protons and 6 neutrons in the nucleus and 6 electrons in orbit around it. Nitrogen: 7 protons and 7 neutrons in the nucleus and 7 electrons in orbit around it. Oxygen: 8 protons and 8 neutrons in the nucleus and 8 electrons in orbit around it. So, the only difference between any of the elements e.g. oxygen and nitrogen is the number of particles in the atoms of each gas. Just as the words 'GOD' and 'DOG' represent totally different things despite being made of the same letters, all the elements in the universe from hydrogen to iron, from gold to tin are all different, look different, behave differently and so on, simply because, in their atoms they have different numbers of the fundamental particles, protons, neutrons and electrons.

Answer 2

The amount of protons an atom has is the atomic number.

ie Hydrogen is 1st as it has 1 proton.

So they are ordered going across from least protons to most protons.

The elements on the Periodic Table are neutral means that there are the same amount of protons as there are electrons.

Neutrons come from the Atomic Mass. You take the atomic mass, subtract the atomic number (amount of protons) and then you have the amount of neutrons.

Answer 3

All three make up an atom. Protons and neutrons are in the center of the atom which is called the nucleus. Electrons are on the outside of the nucleus spinning around at certain distances. Depending on the number of all three determines what type of atom you have.

Answer 4

Yes. Only protons and neutrons are found in the nucleus, electrons orbit the nucleus in energy levels. Only hydrogen does not have any neutrons in its nucleus.
