All About The Differences Between Acid and Base with Example

Have you ever tried lemon? How does it taste? Sour right? Yep, it’s because lemon contains citric acid. Lemon itself, is an example from various fruits that has a sour taste. How about the base taste? Have you ever accidentally swallowed soap bubbles and tasted it? If you ever experienced that, it tastes bitter isn’t […]

Drawbacks of Democritus Atomic Theory – Origins and Impacts

Democritus (c. 460 BCE – c. 370 BCE) was a pre-Socratic Ancient Greek philosopher who explained about composition of matter. He also pioneered the concept of atoms which spurred the evolution of atomic theories. As a result, more and more atomic theories came up from different scientists from time to time until the proposal of […]

7 Advantages and Disadvantages of Dalton’s Atomic Theory

Atom is a part of particle of a substance which is gas, liquid or solid (metal). The word of atom firstly punctuated by a philosopher named Democritus. Atom model is an illustration of atom based on theoretical studies that is supported by experiment. The weaknesses of Democritus atom model is it is not supported by […]

Atomic Theory by Rutherford – Model, Experiment, and Limitations

Atomic theory by Rutherford is the next atomic theory after the J.J. Thomson theory. We know that after the discovery of Dalton, the scientist were able to develop some great theories and experiments to help us understand the chemical models of atom. After Thompson’s atomic theory, Ernest Rutherford, and many more the experiment is held by […]

Atomic Theory by JJ Thomson – Structure – Model – Experiment

Atomic theory is one of the most basic study in chemistry. This theory opened the possibility to discover other new theories which then will be very useful in the chemistry study in general. One of the early scientist who discovered chemistry model of atoms was J.J. Thomson. He conducted the experiment to find out the new […]

5 Democritus Theory of Atoms – Structure – Model – Development

Democritus is one of the most influential people in the chemistry. He was the first person who discovered the theory of atom. We know his discovery as Democritus theory of atoms. This theory is one of the most important theory in the atomic theory and organic chemistry in general. His theory has effectively given the great foundation […]

Atomic theory is one of the most basic and important study in the chemistry. Atomic theory gives the basic understanding about atomic structure which also presents the properties of chemical element and matter. There many atomic theory which are very influential not only for chemistry theory, bu also to other studies like biology, physics, mechanical […]

5 Postulates of John Dalton – Atomic Theory – Studies – Drawbacks

Atomic theory is one of the great discovery in the chemistry study. This is the basic concept which gives the better understanding about many branches of chemistry, both in Branches of Organic Chemistry and Branches of Inorganic Chemistry. One of the popular name in atomic studies is John Dalton. He released the postulates of john dalton to describe […]

5 Chemistry Models of Atoms – Theory – Scientists – Definition

The concept of atom, especially the chemistry models of atoms, is really important in chemistry study. Atom is the tiniest of an element. Atom consists of three main parts which are proton, electron and neutron. Knowing the basic concept of proton, electron, neutron is helpful to understand the chemistry models of atoms. This article will cover […]
