Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third, all the atoms were different from all the other atoms. Fourth, atoms of different elements combined together in equal numbers to form compounds. Fifth and final

Chromium is part of the periodic table this element has the atomic number of 24 which means that it has 24 protons and 24 electrons. Its atomic mass is 51.996, but when reduced it will be 52. The density of the element is 7.19, and the temperature for it is 20 Celsius. And the melting point of the element is going to be 1907 Celsius. This information gives you the idea of what my element has. The history of the element is very interesting, because it came from a Greek word. But it was discovered

I am doing a project about the element neon, which has an atomic mass of 20.1797g/mol, which is from how many protons and neutrons there are a melting point of – 248.6C; a boiling point of -246.1C and to top it of is classified as a noble gas how does it get that cold it has never even reached. You may know neon from the open sign at your local gas station. It actually has very few uses and that is the main one. The thing is neon glows when electrically simulated. The name neon comes from the

Figure 1 is the number of protons in the model. The number of protons corresponds to the atomic number, which can be found on the Periodic Table. Chlorine has a total of 17 protons, so there are 17 protons drawn on the Bohr model. From the inside out, the number of electrons drawn on each shell are 2, 8 and 7. The third piece of information taken from Figure 1 is that Chlorine has a total of 18 electrons. This means that there is one more electron than there is protons. Because of this, chlorine

Everything is made up of atoms. Atoms are made of electrons, protons, and neutrons. Electrons shape pairs with the magnetism from the two paired electrons exactly cancelling, in almost all materials. Magnets are not paired up like they are in other materials. The electrons then line up, and scatter around the protons, that develop a magnetic field. Therefore, those atoms are microscopic magnets. Then atoms form a line called crystals. A group of these magnetic crystals form a realm of magnetic fields

Although difficult to imagine, there existed a point in time where people lived in an environment where everything was visually there, but what it was made up of remained a thoughtless mystery. Today, this is why atomic theory is an important basis for the foundation of chemistry, physics, and various other scientific discoveries. Without atomic theory, the basic building blocks of the world would remain unclear, which would make understanding the study of science almost impossible. Atomic theory

Dear Mrs. H, I am now currently in the year of 1897, and I feel as if I need to write you a letter because I haven’t seen you in ages and you’ve taught me so much so I need your advice. The atomic structure in my point of view is completely different to John Dalton’s. His model influenced me to create mine; Dalton’s claim was that matter consists of atoms, which are indestructible, atoms of the same element were identical in mass and some properties, but atoms from different elements don’t have similar

History In 1898, a Scottish chemist by the name Sir William Ramsay and an English chemist named Morris M. Travers discovered Neon. Named after the Greek word neos meaning new, it was discovered by the chemists after attempting to identify the tiny amount of liquid left over from oxygen, nitrogen, carbon dioxide, and argon after being extracted from liquid air, also known as distillation. ("Neon," 2000) After the extraction was complete they found three new sets of spectral lines. This led to the

Introduction: All materials with which we work are made up of atoms. Though atoms are neutral, the atoms themselves are made up of charged particles: Protons which are positively charged, neutrons which have no charge, and electrons which are negatively charged. Even though atoms are neutral, charge can still be transferred through the fact that not all atoms or molecules hold on to their electrons with the same strength, and when two substances are in contact the transfer of charge can occur.
