John Dalton believed that atoms were the fundamental building blocks of matter, and that they could not be created, destroyed or split. However he was wrong, because atoms are made out of subatomic particles such as Protons, Neutrons and Electrons - and later still, it was discovered Protons and Neutrons too are made of even smaller particles.

What is the number of protons neutrons and electrons of carbon 12?
Carbon-12 has 6 protons, neutrons, and electrons.
How many neutrons and electrons are present in 19 fluorine and 16 Oxygen?
electrons in O16 is 16 while neutrons is 32
How many protons neutrons and electrons are there in sulfur?
There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons

How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons?
Ernest Rutherford discovered protons in the nuclei of atoms in 1918, and James Chadwick discovered neutrons in 1932.
What shows up electrons?

Why is the periodic table of elements an important tool for scientists?
It tells the amount of protons neutrons and electrons are in an atom.
Do neutrons and electrons form a chemical bond?
Electrons do but neutrons do not
How where atoms discovered to be made of electrons?
1. Atoms are made from the atomic nucleus (protons plus neutrons) and electrons.2. For the discovery of electrons is credited J. J. Thomson in 1897.

18 protons 18 electrons 22 neutrons
How has the idea of the atom developed and changed over time?
At first we didn't now that the atom existed. It was Einstein who discovered that pollen grains were moving in a glass of water. Why? It was because as he later confirmed that the water particles were pushing it in an unbalanced way. Other scientists later discovered that there are protons, neutrons and electrons in an atom.
How many neutrons are in electrons?
Zero. Electrons are not made up of neutrons.
