Beryllium is in Group 2, Period 2 of the Periodic Table of the Elements. And because it is in Period 1, Beryllium has one electron on its outermost shell. It also means that, because it is in the first group, it only has one shell (or energy level) around the nucleus, which we call the outermost shell of the atom. This means that Hydrogen is the smallest and lightest atom in the Periodic Table. Hydrogen is the first atom found in the top left corner of the Periodic Table of Elements. For instance, the most basic atom is Hydrogen. This allows children to understand how scientists have organized the elements into a series of groups and periods within a matrix. By offering to work with both the atomic structure and the Periodic Table of Elements, we are reconciling two scientific components that are often studied separately, and yet, that need to be learned together. Because everything is made of matter, atoms, and elements understanding how atoms are composed and how they bond is fundamental. Learning about atoms is a key component that will lead to understanding all other chemistry concepts as well as physical science. That said, the Bohr Atomic Model isn’t inaccurate in its structure. Atoms do have variable electrons circulating around a nucleus with observable parts (protons and neutrons) of which its mass is known. Therefore, the Bohr Model can serve as a way to build each atom in its most simplistic fixed form. It is an excellent hands-on tool that helps young learners understand the concept of the smallest particles of matter and learn how scientists have classified atoms in the Periodic Table of Elements, which we will discuss in this post. This theory has been revised and replaced with more realistic theories which suggest that electrons travel within energy levels (shells) under the influence of various factors. The Bohr Model was presented by physicist Niel Bohr in 1913 as a theoretical atomic model. It resembles a solar system with electrons orbiting a nucleus in a predictable pattern. The Bohr Model does not claim to be the most accurate model, but it is still the preferred introductory model for young learners. Bohr’s Atomic Model – Command Cards Bohr’s Atomic Model – Command Cards Atoms are still represented through many models aiming to replicate the probabilistic laws of quantum mechanics, with electrons unpredictably moving in a circular motion within the perimeter of a nucleus. We are pleased to introduce our brand new chemistry material, the Bohr’s Atomic Model – Complete Set! Chemistry begins with the study of the smallest building blocks of life, atoms. ![]()
