Sep 30, 2019Atomic Theory. John Dalton (1766-1844) is the scientist credited for proposing the atomic theory. This theory explains several concepts that are relevant in the observable world: the composition of a pure gold necklace, what makes the pure gold necklace different than a pure silver necklace, and what occurs when pure gold is mixed with pure copper.

The atomic number of an atom is the same as the number of protons it has. For example, hydrogen has one proton and is atomic number 1. For example, hydrogen has one proton and is atomic number 1. Each helium atom has two protons, so the element is atomic number 2.Author: Anne Marie Helmenstine, Ph.D.People also askWhat is the basic atomic structure?What is the basic atomic structure?The basics of atomic structure are as follows: Protons are positively charged particles,weighing 1 atomic mass unit (10-24 grams) and located in the nucleus.
